The Force is a metaphysical and ubiquitous power in the Star Wars fictional universe . "Force-sensitive" characters use the Force throughout the franchise. Heroes like the Jedi seek to "become one with the Force", matching their personal wills with the will of the Force, while the Sith and other villains exploit the Force and try to bend it toward their own selfish and destructive desires. The Force has been compared to aspects of several world religions, and the phrase " May the Force be with you " has become part of pop culture vernacular .
180-619: George Lucas created the concept of the Force to address character and plot developments in Star Wars (1977). He also wanted to "awaken a certain kind of spirituality" in young audiences, suggesting a belief in God without endorsing any specific religion. He developed the Force as a nondenominational religious concept, "distill[ed from] the essence of all religions", premised on the existence of God and distinct ideas of good and evil . Lucas said there

These compartments or regions include the outer membrane, intermembrane space , inner membrane , cristae , and matrix . Although most of a eukaryotic cell's DNA is contained in the cell nucleus , the mitochondrion has its own genome ("mitogenome") that is substantially similar to bacterial genomes. This finding has led to general acceptance of

Abrams respected that Lucas had established midi-chlorians' effect on some characters' ability to use the Force. However, as a child, he interpreted Obi-Wan Kenobi 's explanation of the Force in Star Wars to mean that any character could use its power, and that the Force was more grounded in spirituality than science. Abrams retained

He also became good friends with fellow acclaimed student filmmaker and future Indiana Jones collaborator, Steven Spielberg and Martin Scorsese . A group of friends, which included Chris Lewis and Don Glut , started the Clean Cut Cinema Club. Lucas, Kleiser and Lewis then formed a short-lived production company called Sunrise Productions with offices on Sunset Boulevard. There they would make up stage names for themselves, Lucas calling himself Lucas Beaumont. Their only project would be
1800-482: A concept. Although Chris Taylor suggested fans want less detail, not more, in explaining the Force, Chris Bell argues that the introduction of midi-chlorians provided depth to the franchise and fomented engagement among fans and franchise writers. Religion expert John D. Caputo writes, "In the 'Gospel according to Lucas' a world is conjured up in which the intractable oppositions that have tormented religious thinkers for centuries are reconciled ... The gifts that

Mitochondria have long been recognized for their central role in the intrinsic pathway of apoptosis , a form of PCD. In recent decades, they have also been identified as a signalling hub for much of the innate immune system . The endosymbiotic origin of mitochondria distinguishes them from other cellular components, and
2700-401: A high enough midi-chlorian count to feel and use the Force. Midi-chlorians are sentient, and arguably were the first species to emerge in the Star Wars universe. The species was a foundation of all life, as some deemed life impossible without midi-chlorians, and ultimately resided in all living beings, connecting two aspects of the Force. The Living Force (also known as a spirit or life essence)

Mitochondrial matrix calcium levels can reach the tens of micromolar levels, which is necessary for the activation of isocitrate dehydrogenase , one of the key regulatory enzymes of the Krebs cycle . The relationship between cellular proliferation and mitochondria has been investigated. Tumor cells require ample ATP to synthesize bioactive compounds such as lipids , proteins , and nucleotides for rapid proliferation. The majority of ATP in tumor cells
4500-496: A religion based on the Force. Practitioners of Jediism pray to and express gratitude to the Force. Scientists are mostly skeptical about a "real world" explanation for the Force. Astrophysicist Jeanne Cavelos says in The Science of Star Wars that explaining the Force is particularly difficult because "it does so many different things". Force powers like precognition imply the time travel of information. Cavelos explores

Lucas then set his sights on adapting Flash Gordon , an adventure serial from his childhood that he fondly remembered. When he was unable to obtain the rights, he set out to write an original space adventure that would eventually become Star Wars . Despite his success with his previous film, all but one studio turned Star Wars down. It

In 1970s San Francisco , where Lucas lived when he wrote the drafts that became Star Wars , New Age ideas that incorporated the concept of qi and other notions of a mystical life-force were "in the air" and widely embraced. Lucas used the term the Force to "echo" its use by Canadian cinematographer Roman Kroitor in Arthur Lipsett 's 21-87 (1963),
6480-500: Is a significant interplay between the mitochondrion and ER with regard to calcium. The calcium is taken up into the matrix by the mitochondrial calcium uniporter on the inner mitochondrial membrane . It is primarily driven by the mitochondrial membrane potential . Release of this calcium back into the cell's interior can occur via a sodium-calcium exchange protein or via "calcium-induced-calcium-release" pathways. This can initiate calcium spikes or calcium waves with large changes in

Filoni credits the prequel films for better developing the concept of the Force, particularly the idea of a balance between the light and dark sides. Obi-Wan Kenobi describes the Force as "an energy field created by all living things" in Star Wars . In The Phantom Menace , Qui-Gon says microscopic lifeforms called midi-chlorians, which exist inside all living cells, allow some characters to be Force-sensitive; characters must have

Despite this, he has remained an independent filmmaker away from Hollywood for most of his career. After graduating from the University of Southern California in 1967, Lucas moved to San Francisco and co-founded American Zoetrope with filmmaker Francis Ford Coppola . He wrote and directed THX 1138 (1971), based on his student short Electronic Labyrinth: THX 1138 4EB , which

In humans, brown adipose tissue is present at birth and decreases with age. Mitochondrial fatty acid synthesis (mtFASII) is essential for cellular respiration and mitochondrial biogenesis. It is also thought to play a role as a mediator in intracellular signaling due to its influence on
8100-643: Is sometimes referred to in terms of "dark" and "light" sides, with villains like the Sith drawing on the dark side to act aggressively while the Jedi use the light side for defense and peace. According to Filoni, Lucas believed a character's intentions when using the Force—their "will to be selfless or selfish"—is what distinguishes light and dark sides. The Force is also used by characters who are neither Jedi nor Sith, such as Leia Organa and Kylo Ren . Characters throughout
8280-479: Is the energy generated by all living things. Through midi-chlorians, it is fed into the Cosmic Force, which bounds all things and communicates with living sentient beings. In 1981, Lucas compared using the Force to yoga , saying any character can use its power. Dave Filoni said in 2015 that all Star Wars characters are "Force intuitive": some characters, like Luke Skywalker , are aware of their connection to

After the success of American Graffiti and prior to the beginning of filming on Star Wars , Lucas was encouraged to renegotiate for a higher fee for writing and directing Star Wars than the US$ 150,000 agreed. He declined to do so, instead negotiating for advantage in some of the as-yet-unspecified parts of his contract with Fox, in particular, ownership of licensing and merchandising rights (for novelizations , clothing, toys, etc.) and contractual arrangements for sequels. Lucasfilm has earned hundreds of millions of dollars from licensed games, toys, and collectibles created for

This version trims "the Force of Others" to "the Force", makes a single reference to the Force's seductive " dark side ", distills an explanation of the Force to 28 words, and eliminates the Kyber Crystal. Producer Gary Kurtz , who studied comparative religion in college, had long discussions with Lucas about religion and philosophy throughout
12960-475: The CGI film Strange Magic , his first musical. The film was produced at Skywalker Ranch . Gary Rydstrom directed the movie. At the same time the sequel trilogy was announced, a fifth installment of the Indiana Jones series also entered pre-development phase with Harrison Ford and Steven Spielberg set to return. Lucas originally did not specify whether the selling of Lucasfilm would affect his involvement with
13140-835: The Chicago-based not-for-profit After School Matters, of which Hobson is the chair. On April 15, 2016, it was reported that Lucas had donated between $ 501,000 and $ 1 million through the Lucas Family Foundation (now the Hobson/Lucas Family Foundation) to the Obama Foundation , which is charged with overseeing the construction of the Barack Obama Presidential Center on Chicago's South Side . In 2021, Lucas and his wife Mellody Hobson made
13320-585: The Clones (2002) and Revenge of the Sith (2005). He last collaborated on the CGI-animated movie and television series of the same name, Star Wars: The Clone Wars (2008–2014, 2020), the war film Red Tails (2012) and the CGI film Strange Magic (2015). Lucas is also known for his collaboration with composer John Williams , who was recommended to him by Spielberg, and with whom he has worked for all
13500-406: The Clones . The final prequel, Episode III – Revenge of the Sith , began production in 2002 and was released in 2005. Numerous older fans and critics at the time considered the prequels more mixed compared to the original trilogy, though they were box office successes and popular with younger fans. In 2004, Lucas reflected that his transition from independent to corporate filmmaker mirrored
13680-474: The Clones and Revenge of the Sith , and featured the last Star Wars stories in which Lucas was involved in a major way. In 2012, Lucas self-funded and served as executive producer for Red Tails , a war film based on the exploits of the Tuskegee Airmen during World War II . He also took over directing of reshoots while director Anthony Hemingway worked on other projects. I'm moving away from
13860-535: The Crystal Skull (2008), and served as an executive producer, with a cursory involvement in pre and post-production, on The Dial of Destiny (2023). In 1997, Lucas re-released the original Star Wars trilogy as part of a Special Edition featuring several modifications; home media versions with further changes were released in 2004 and 2011. He returned to directing with a Star Wars prequel trilogy comprising The Phantom Menace (1999), Attack of
14040-528: The Emperor was later shifted to Return of the Jedi (1983), and the dark side of the Force was treated as The Empire Strikes Back ' s main villain. The Phantom Menace (1999) introduces midi-chlorians (or midichlorians ), microscopic creatures that connect characters to the Force. Lucas later requested a passage about midi-chlorians be retroactively added to notes written in August 1977 expanding on
14220-439: The Force "a mixture of what appears to be ESP and early Christian faith." It has been studied in a religious context from an academic perspective. The Magic of Myth compares the sharp distinction between the good "light side" and evil "dark side" of the Force to Zoroastrianism , which posits that "good and evil, like light and darkness, are contrary realities". The connectedness between the light and dark sides has been compared to
14400-472: The Force and how it works, the more it took away from its core meaning. Kotaku suggests Rian Johnson depicted more nuance in the Force in The Last Jedi than Lucas did in his films. According to Rob Weinert-Kendt, the "Force theme" in John Williams ' score represents the power and responsibility of wielding the Force. Paranormal abilities like the Force are a common device in science fiction, and
14580-483: The Force and science-fiction tropes . These Ewok films have been described as depicting "sorcery" that is distinct from the Force powers depicted in the first six Star Wars films. Drawing from the Star Wars roleplaying game sourcebook he co-authored in 1987, Bill Slavicsek says that "The Ewoks' mystical beliefs contain many references to the Force, though it is never named as such." In his 1977 review of Star Wars , Vincent Canby of The New York Times called
14760-458: The Force can do." Johnson observed that every Star Wars movie introduces new Force powers to meet that film's story needs. Star Wars Rebels producer Dave Filoni cites several influences on how the Force is used in the show. The character Bendu —named in homage to the term Lucas originally associated with the Jedi—does not align with the franchise's normal dark-or-light duality, and this role
14940-494: The Force has been compared to the role magic plays in the fantasy genre. The Star Wars films illustrate that characters not familiar with the particulars of the Force associate it with mysticism and magic, such as when an Imperial officer alludes to the "sorcerer's ways" of Darth Vader. The depiction of the Force in Star Wars has been compared to that of magic in Harry Potter , with the former being described as more of
15120-517: The Force, which is ... Lucas's tribute to something beyond science: imagination, the soul, God in man ... It appears in various contradictory and finally nonsensical guises, a facile and perfunctory bow to metaphysics. I wish that Lucas had had the courage of his materialistic convictions, instead dragging in a sop to a spiritual force the main thrust of the movie so cheerfully ignores. The introduction of midi-chlorians in The Phantom Menace
15300-498: The Force, while characters such as Han Solo draw upon the Force unconsciously. Filoni said the most potent Force users are characters whose midi-chlorian count provides a natural affinity for using the Force and who undertake intense training and discipline. Rogue One (2016) portrays the Force more as a religion "than simply a way to manipulate objects and people". In the years following the Great Jedi Purge depicted in
15480-419: The Force. It's depicted as ... something supernatural within this universe, but it's not the same thing as a personal god that Christians or Jews or Muslims might believe in. It's this impersonal force that is in some ways this neutral, impersonal energy that is out there to be used for good or for evil." At one point, Francis Ford Coppola suggested to George Lucas that they use their combined fortunes to start
15660-704: The Fourth be with you". The expression was intentionally similar to the Christian dominus vobiscum , "the Lord be with you". President Ronald Reagan in 1985 said "the Force is with us", referring to the United States , to create the Strategic Defense Initiative (itself often nicknamed Star Wars ) to protect against Soviet ballistic missiles . Some weeks earlier, Reagan had compared
15840-436: The Jedi masters enjoy have a perfectly plausible scientific basis, even if its ways are mysterious". Characters' faith in the Force reinforces Rogue One ' s message of hope. The A.V. Club said Rian Johnson's depiction of the Force in The Last Jedi goes "beyond George Lucas' original transcendental concept". Polygon said Johnson's film "democratize[s] the Force", depicting Force sensitivity in characters from outside
16020-571: The Jedi, Raiders of the Lost Ark , Indiana Jones and the Temple of Doom , and Indiana Jones and the Last Crusade ). After Lucas sold Lucasfilm to Disney, Williams stayed on board with the franchise, and continued to score the remaining three films of the " Skywalker Saga " ( The Force Awakens , The Last Jedi , and The Rise of Skywalker , for which he received a further three Oscar nominations), after which he announced his "retirement" from
16200-400: The Los Angeles staff go. By the same year, the corporate subsidiary had been discontinued and its business was absorbed into the various divisions of Lucasfilm. Lucas founded Industrial Light & Magic in 1975, he wanted his 1977 film Star Wars to include visual effects that had never been seen on film before. After discovering that the in-house effects department at 20th Century Fox
16380-565: The MAM provided insight into the mechanistic basis underlying such physiological processes as intrinsic apoptosis and the propagation of calcium signaling, but it also favors a more refined view of the mitochondria. Though often seen as static, isolated 'powerhouses' hijacked for cellular metabolism through an ancient endosymbiotic event, the evolution of the MAM underscores the extent to which mitochondria have been integrated into overall cellular physiology, with intimate physical and functional coupling to
16560-594: The MAM, which may comprise up to 20% of the mitochondrial outer membrane, the ER and mitochondria are separated by a mere 10–25 nm and held together by protein tethering complexes. Purified MAM from subcellular fractionation is enriched in enzymes involved in phospholipid exchange, in addition to channels associated with Ca signaling. These hints of a prominent role for the MAM in the regulation of cellular lipid stores and signal transduction have been borne out, with significant implications for mitochondrial-associated cellular phenomena, as discussed below. Not only has
16740-611: The Main Title Theme, the Force Theme (less commonly referred to as Obi Wan Kenobi's Theme), the Rebel Alliance Theme and Princess Leia's Theme (all introduced in this film) repeatedly. Subsequent films also added to the catalog of themes for different characters, factions, and locations. The score was released to critical acclaim and won Williams his third Academy Award for Best Original Score . The score
16920-454: The Whills, beings that "control the universe" and "feed off the Force." He elaborated that individuals function as "vehicles for the Whills to travel around in", and that midi-chlorians "communicate with the Whills [who] in a general sense ... are the Force." After selling Lucasfilm to Disney in 2012, Lucas said his biggest concern about the franchise's future was the Force being "muddled into
17100-586: The [ Star Wars ] blessing is precisely a request for hope for others (" May the Force be with you"), whereas Reagan's claim sounds like a possessive assertion ("The Force is with us"). George Lucas George Walton Lucas Jr. (born May 14, 1944) is an American filmmaker and philanthropist. He created the Star Wars and Indiana Jones franchises and founded Lucasfilm , LucasArts , Industrial Light & Magic and THX . He served as chairman of Lucasfilm before selling it to The Walt Disney Company in 2012. Nominated for four Academy Awards , he
17280-510: The area of the inner membrane is about five times as large as that of the outer membrane. This ratio is variable and mitochondria from cells that have a greater demand for ATP, such as muscle cells, contain even more cristae. Mitochondria within the same cell can have substantially different crista-density, with the ones that are required to produce more energy having much more crista-membrane surface. These folds are studded with small round bodies known as F 1 particles or oxysomes. The matrix
17460-417: The blood. Here, the addition of oxaloacetate to the mitochondrion does not have a net anaplerotic effect, as another citric acid cycle intermediate (malate) is immediately removed from the mitochondrion to be converted to cytosolic oxaloacetate, and ultimately to glucose, in a process that is almost the reverse of glycolysis . The enzymes of the citric acid cycle are located in the mitochondrial matrix, with
17640-404: The business ... From the company, from all this kind of stuff. —George Lucas on his future career plans In January 2012, Lucas announced his retirement from producing large blockbuster films, and instead re-focusing his career on smaller, independently budgeted features. In June 2012, it was announced that producer Kathleen Kennedy , a long-term collaborator with Steven Spielberg and
17820-410: The cell can regulate an array of reactions and is important for signal transduction in the cell. Mitochondria can transiently store calcium , a contributing process for the cell's homeostasis of calcium. Their ability to rapidly take in calcium for later release makes them good "cytosolic buffers" for calcium. The endoplasmic reticulum (ER) is the most significant storage site of calcium, and there
18000-440: The cell cycle suggesting that there is a relationship between the abundance of ATP and the cell's ability to enter a new cell cycle. ATP's role in the basic functions of the cell make the cell cycle sensitive to changes in the availability of mitochondrial derived ATP. The variation in ATP levels at different stages of the cell cycle support the hypothesis that mitochondria play an important role in cell cycle regulation. Although
18180-483: The characters' relationship. Chris Taylor called the Force "largely a mystery" in Star Wars . Taylor ascribes the "more poetic, more spiritual ... and more demonstrative" descriptions of the Force in The Empire Strikes Back to Lawrence Kasdan , who co-wrote the film, but says the film does little to expand audiences' understanding of it. In 1997, Lucas said that the more detail he articulated about
18360-470: The climax of The Rise of Skywalker , and Luke's and Leia's spirits watch over her at the film's conclusion. In an early draft of Return of the Jedi , Lucas planned to resurrect Obi-Wan and Yoda at the climax, and some drafts included scenes of the two helping Luke stop the Emperor. The final arc of The Clone Wars ' sixth season reveals that Qui-Gon Jinn learned how to transition into the "cosmic Force" from entities who represent various emotions; Yoda hears
18540-447: The company. The sale reflected Lucas's desire to stop the cash flow losses from his seven-year research projects associated with new entertainment technology tools, as well as his company's new focus on creating entertainment rather than tools. As of June 1983, Lucas was worth $ 60 million, but he met cash-flow difficulties following his divorce that year, concurrent with the sudden dropoff in revenues from Star Wars licenses following
18720-639: The creative differences between him and the producers of The Force Awakens . Lucas went on to say that he needed to support the company and its employees who were going to suffer financially. Lucas described the previous six Star Wars films as his "children" and defended his vision for them, while criticizing The Force Awakens for having a "retro feel", saying: "I worked very hard to make them completely different, with different planets, with different spaceships – you know, to make it new." Lucas also drew some criticism and subsequently apologized for his remark likening Disney to "white slavers". In 2015, Lucas wrote
18900-415: The creator and executive producer for a second Star Wars animated series on Cartoon Network, Star Wars: The Clone Wars which premiered with a feature film of the same name before airing its first episode. The supervising director for this animated series was Dave Filoni , who was chosen by Lucas and closely collaborated with him on its development. This series bridged the events between Attack of
19080-436: The cycle, increasing all the other intermediates as one is converted into the other. Hence, the addition of any one of them to the cycle has an anaplerotic effect, and its removal has a cataplerotic effect. These anaplerotic and cataplerotic reactions will, during the course of the cycle, increase or decrease the amount of oxaloacetate available to combine with acetyl-CoA to form citric acid. This in turn increases or decreases
19260-452: The cytosol. This type of cellular respiration , known as aerobic respiration , is dependent on the presence of oxygen . When oxygen is limited, the glycolytic products will be metabolized by anaerobic fermentation , a process that is independent of the mitochondria. The production of ATP from glucose and oxygen has an approximately 13-times higher yield during aerobic respiration compared to fermentation. Plant mitochondria can also produce
19440-667: The deceased Qui-Gon's voice in Attack of the Clones (2002), and he reveals in Revenge of the Sith that he has contact with Qui-Gon. A short story by Claudia Gray depicts Obi-Wan learning this technique from Qui-Gon in the years leading up to Star Wars . The Force plays an important role in several Star Wars plot lines. Anakin Skywalker's rise as a Jedi, descent into the Sith Lord Darth Vader, and redemption back to
19620-425: The distribution of these organelles is also correlated with the endoplasmic reticulum . Recent evidence suggests that vimentin , one of the components of the cytoskeleton, is also critical to the association with the cytoskeleton. The mitochondria-associated ER membrane (MAM) is another structural element that is increasingly recognized for its critical role in cellular physiology and homeostasis . Once considered
19800-486: The end of the trilogy. The success of the first Star Wars film also resulted in more attention focused on Lucas, both positive and negative, attracting wealth and fame, but also many people who wanted Lucas's financial backing or just to threaten him. Following the release of the first Star Wars film, Lucas worked extensively as a writer and producer, including on the many Star Wars spinoffs made for film, television and other media. Lucas acted as executive producer for
19980-426: The endomembrane system. The MAM is enriched in enzymes involved in lipid biosynthesis, such as phosphatidylserine synthase on the ER face and phosphatidylserine decarboxylase on the mitochondrial face. Because mitochondria are dynamic organelles constantly undergoing fission and fusion events, they require a constant and well-regulated supply of phospholipids for membrane integrity. But mitochondria are not only
20160-470: The enzymes, the major functions include oxidation of pyruvate and fatty acids , and the citric acid cycle . The DNA molecules are packaged into nucleoids by proteins, one of which is TFAM . The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP ), through respiration and to regulate cellular metabolism . The central set of reactions involved in ATP production are collectively known as
20340-458: The estate of Steve Jobs . Lucas worked as a creative consultant on the Star Wars sequel trilogy 's first film, The Force Awakens . Lucas's involvement included attending early story meetings; according to Lucas, "I mostly say, 'You can't do this. You can do that.' You know, 'The cars don't have wheels. They fly with antigravity.' There's a million little pieces ... I know all that stuff." Lucas's son Jett told The Guardian that his father
20520-506: The event the deal closes, to donate the majority of the proceeds to his philanthropic endeavors." Lucas also spoke on the matter: "For 41 years, the majority of my time and money has been put into the company. As I start a new chapter in my life, it is gratifying that I have the opportunity to devote more time and resources to philanthropy." In 2005, Lucas gave $ 1 million to help build the Martin Luther King Jr. Memorial on
20700-620: The exception of succinate dehydrogenase , which is bound to the inner mitochondrial membrane as part of Complex II. The citric acid cycle oxidizes the acetyl-CoA to carbon dioxide, and, in the process, produces reduced cofactors (three molecules of NADH and one molecule of FADH 2 ) that are a source of electrons for the electron transport chain , and a molecule of GTP (which is readily converted to an ATP). The electrons from NADH and FADH 2 are transferred to oxygen (O 2 ) and hydrogen (protons) in several steps via an electron transport chain. NADH and FADH 2 molecules are produced within
20880-453: The exposure of mitochondrial elements to the cytosol can trigger the same pathways as infection markers. These pathways lead to apoptosis , autophagy , or the induction of proinflammatory genes. Mitochondria contribute to apoptosis by releasing cytochrome c , which directly induces the formation of apoptosomes . Additionally, they are a source of various damage-associated molecular patterns (DAMPs). These DAMPs are often recognised by
21060-403: The film series into a "Saga". In 1994, Lucas began work on the screenplay of the first prequel, tentatively titled Episode I: The Beginning . In 1997, to celebrate the 20th anniversary of Star Wars , Lucas restored the original trilogy and made numerous modifications using newly available digital technology to bring them closer to his original vision. The films were re-released in theaters as
21240-512: The film. In October 2016, Lucas announced his decision to not be involved in the story of the film but would remain an executive producer. In 2016, Rogue One: A Star Wars Story , the first film of a Star Wars anthology series was released. It told the story of the rebels who stole the plans for the Death Star featured in the original Star Wars film, and it was reported that Lucas liked it more than The Force Awakens . The Last Jedi ,
21420-517: The films in both of these franchises. He also produced and wrote a variety of films and television series through Lucasfilm between the 1970s and the 2010s. Lucas is one of history's most financially successful filmmakers . He directed or wrote the story for ten of the 100 highest-grossing movies at the North American box office, adjusted for ticket-price inflation. Through his companies Industrial Light and Magic and Skywalker Sound , Lucas
21600-437: The first film Lucas had directed in over two decades. Following the release of the first prequel, Lucas announced that he would also be directing the next two, and began working on Episode II . The first draft of Episode II was completed just weeks before principal photography, and Lucas hired Jonathan Hales , a writer from The Young Indiana Jones Chronicles , to polish it. It was completed and released in 2002 as Attack of
21780-465: The first four Indiana Jones films, which his colleague and good friend Steven Spielberg directed. Craig Barron , who worked at ILM as part of the matte painting department, told Star Wars Insider that Lucas liked to spend time with the department's painters and often spoke of what movies he wanted to make. According to Barron, Lucas had wanted to make a film about Alexander the Great , but this film
21960-541: The forces of the world we live in. National Geographic compared the Higgs boson 's role as "carrier" of the Higgs field to the way Jedi are "carriers" of the Force. A previsualization video highlighting the idea of "kicking someone's ass with the Force" steered LucasArts game designers toward producing The Force Unleashed (2008), which sold six million copies as of July 2009. In 2009, Uncle Milton Industries released
22140-420: The franchise use their Force powers in myriad ways, including Obi-Wan using a "mind trick" to undermine a stormtrooper's will, Darth Vader choking subordinates without touching them, Qui-Gon Jinn repelling several battle droids at once, Rey lifting a large pile of rocks, and Kylo Ren stopping blaster fire in mid-air. Film and television use of the Force is sometimes accompanied by a sound effect, such as
22320-432: The franchise. The original Star Wars film went through a tumultuous production, and during editing, Lucas suffered chest pains initially feared to be a heart attack, but actually a fit of hypertension and exhaustion. The effort that Lucas exerted during post-production for the film, and its subsequent sequels, caused strains on his relationship with his wife Marcia Lucas, and was a contributing factor to their divorce at
22500-544: The idea of the Force having a light and a dark side, and some characters' seduction by the dark side helps create conflict for the story. Pablo Hidalgo of the Lucasfilm Story Group gave his "blessing" for writer-director Rian Johnson to introduce a new Force power in The Last Jedi (2017) "if the story required it and if it felt like it stretches into new territory but doesn't break the idea of what
22680-549: The inner membrane (TIM) complex or via OXA1L . In addition, there is a membrane potential across the inner membrane, formed by the action of the enzymes of the electron transport chain . Inner membrane fusion is mediated by the inner membrane protein OPA1 . The inner mitochondrial membrane is compartmentalized into numerous folds called cristae , which expand the surface area of the inner mitochondrial membrane, enhancing its ability to produce ATP. For typical liver mitochondria,
22860-410: The inner membrane impermeable, and its disruption can lead to multiple clinical disorders including neurological disorders and cancer. Unlike the outer membrane, the inner membrane does not contain porins, and is highly impermeable to all molecules. Almost all ions and molecules require special membrane transporters to enter or exit the matrix. Proteins are ferried into the matrix via the translocase of
23040-785: The inner mitochondrial membrane ( NADH dehydrogenase (ubiquinone) , cytochrome c reductase , and cytochrome c oxidase ). At complex IV , O 2 reacts with the reduced form of iron in cytochrome c : O 2 + 4 H + ( aq ) + 4 Fe 2 + ( cyt c ) ⟶ 2 H 2 O + 4 Fe 3 + ( cyt c ) {\displaystyle {\ce {O2{}+4H+(aq){}+4Fe^{2+}(cyt\,c)->2H2O{}+4Fe^{3+}(cyt\,c)}}} Δ r G o ′ = − 218 kJ/mol {\displaystyle \Delta _{r}G^{o'}=-218{\text{ kJ/mol}}} releasing

This latter reaction "fills up" the amount of oxaloacetate in the citric acid cycle and is therefore an anaplerotic reaction , increasing the cycle's capacity to metabolize acetyl-CoA when
23400-510: The lack of detail about the Force makes it "a religion for the secular age". According to Jennifer Porter, professor of religious studies at the Memorial University of Newfoundland , "the Force is a metaphor for godhood that resonates and inspires within [people] a deeper commitment to the godhood identified within their traditional faith". According to Christian Pastor Clayton Keenan, "the spirituality of 'Star Wars' has to do with
23580-460: The last 13,000 years". The first draft of Star Wars makes two references to "the Force of Others" and does not explain the concept: King Kayos utters the blessing "May the Force of Others be with you all", and he later says "I feel the Force also". The power of the Force of Others is kept secret by the Jedi Bendu of the Ashla, an "aristocratic cult" in the second draft. The second draft offers
23760-483: The levels of bioactive lipids, such as lysophospholipids and sphingolipids . Octanoyl-ACP (C8) is considered to be the most important end product of mtFASII, which also forms the starting substrate of lipoic acid biosynthesis. Since lipoic acid is the cofactor of important mitochondrial enzyme complexes, such as the pyruvate dehydrogenase complex (PDC), α-ketoglutarate dehydrogenase complex (OGDC), branched-chain α-ketoacid dehydrogenase complex (BCKDC), and in
23940-472: The light side of the Force is the main story arc for the first six Star Wars films. Yoda 's arc in the sixth season of The Clone Wars depicts him exploring "bigger questions" about the Force and taking various inspirations from the franchise's expanded universe . In The Force Awakens , Finn 's exposure to the Force helps make him question his training. Writer Rian Johnson used the Force to allow Rey and Kylo Ren to communicate in The Last Jedi , developing
24120-441: The making of a film of his choosing. The film he chose after finding the animation department closed down was Finian's Rainbow (1968) which was being directed by Francis Ford Coppola , who was revered among film school students of the time as a cinema graduate who had "made it" in Hollywood. In 1969, Lucas was one of the camera operators on the classic Rolling Stones concert film Gimme Shelter . In 1969, Lucas moved back to
24300-423: The matrix via the citric acid cycle and in the cytoplasm by glycolysis . Reducing equivalents from the cytoplasm can be imported via the malate-aspartate shuttle system of antiporter proteins or fed into the electron transport chain using a glycerol phosphate shuttle . The major energy-releasing reactions that make the mitochondrion the "powerhouse of the cell" occur at protein complexes I, III and IV in
24480-474: The membrane potential. These can activate a series of second messenger system proteins that can coordinate processes such as neurotransmitter release in nerve cells and release of hormones in endocrine cells. Ca influx to the mitochondrial matrix has recently been implicated as a mechanism to regulate respiratory bioenergetics by allowing the electrochemical potential across the membrane to transiently "pulse" from ΔΨ-dominated to pH-dominated, facilitating
24660-434: The metaphor, saying society is the same way, says we all must get along with each other. In a rough draft of Revenge of the Sith (2005), Palpatine says he "used the power of the Force to will the midichlorians to start the cell divisions that created" Anakin Skywalker. This line was removed as the script progressed. Lucas' story treatments for a potential sequel trilogy involved "a microbiotic world" and creatures known as
24840-479: The mitochondria and may contribute to the decline in mitochondrial function associated with aging. As the proton concentration increases in the intermembrane space, a strong electrochemical gradient is established across the inner membrane. The protons can return to the matrix through the ATP synthase complex, and their potential energy is used to synthesize ATP from ADP and inorganic phosphate (P i ). This process
25020-538: The museum in California. On January 17, 2017, Lucas announced that an eleven-acre campus with green space and the museum's five-story 300,000 square foot building will be constructed over what was a parking lot in Exposition Park , Los Angeles, California. It is due to be completed in 2025. Lucas was also heavily involved and invested in the scoring process for the original Star Wars soundtrack , which
25200-586: The nature of the Force. Lucas based the concept on symbiogenesis , calling midi-chlorians a "loose depiction" of mitochondria . He further said: [Mitochondria] probably had something ... to do with the beginnings of life and how one cell decided to become two cells with a little help from this other little creature who came in, without whom life couldn't exist. And it's really a way of saying we have hundreds of little creatures who live on us, and without them, we all would die. There wouldn't be any life. They are necessary for us; we are necessary for them. Using them in
25380-484: The never completed short "Five, Four, Three", a self-referential and self-deprecating mockumentary about the making of a satirical teen beach movie called "Orgy Beach Party". Lucas was deeply influenced by the Filmic Expression course taught at the school by filmmaker Lester Novros which concentrated on the non-narrative elements of Film Form like color, light, movement, space, and time. Another inspiration
25560-536: The next two Star Wars films, commissioning Irvin Kershner to direct The Empire Strikes Back and Richard Marquand to direct Return of the Jedi , while receiving a story credit on the former and sharing a screenwriting credit with Lawrence Kasdan on the latter. Lucas also gave away his screenwriting credit out of great respect for Leigh Brackett for The Empire Strikes Back after her death from cancer. He also acted as story writer and executive producer on
25740-409: The outer membrane are small (diameter: 60 Å) particles named sub-units of Parson. The mitochondrial intermembrane space is the space between the outer membrane and the inner membrane. It is also known as perimitochondrial space. Because the outer membrane is freely permeable to small molecules, the concentrations of small molecules, such as ions and sugars, in the intermembrane space is the same as in
25920-478: The outer membrane permits proteins in the intermembrane space to leak into the cytosol, leading to cell death. The outer mitochondrial membrane can associate with the endoplasmic reticulum (ER) membrane, in a structure called MAM (mitochondria-associated ER-membrane). This is important in the ER-mitochondria calcium signaling and is involved in the transfer of lipids between the ER and mitochondria. Outside
26100-591: The park. He was interested in comics and science fiction, including television programs such as the Flash Gordon serials. Long before Lucas began making films, he yearned to be a racecar driver, and he spent most of his high school years racing on the underground circuit at fairgrounds and hanging out at garages.

26280-528: The possibility of brain implants or sensors being used to detect users' intent and manipulate energy fields, and compares such discipline to contemporary patients learning to control prosthetics . A scientific explanation of the Force would require new discoveries in physics, such as unknown fields or particles or a fifth force beyond the four fundamental interactions . Flavio Fenton of the Georgia Institute of Technology School of Physics suggests
26460-488: The prequel trilogy, some characters have lost faith in the Force, and the Galactic Empire hunts down surviving Jedi and other Force-sensitive characters. By the time of the events in The Force Awakens , some characters think the Jedi and the Force are myths. Some Force-sensitive characters derive special, psychic abilities from it, such as telekinesis , mind control , and extrasensory perception . The Force
26640-416: The protagonist on a quest. In her 1980 Washington Post review of The Empire Strikes Back , Judith Martin described the Force as "a mishmash of current cultic fashions without any base in ideas. It doesn't seem to be connected with ethics or a code of decent behavior, either." John Simon wrote in his 1977 review of Star Wars for New York magazine: And then there is that distressing thing called
26820-402: The rate of ATP production by the mitochondrion, and thus the availability of ATP to the cell. Acetyl-CoA, on the other hand, derived from pyruvate oxidation, or from the beta-oxidation of fatty acids , is the only fuel to enter the citric acid cycle. With each turn of the cycle one molecule of acetyl-CoA is consumed for every molecule of oxaloacetate present in the mitochondrial matrix, and
27000-455: The reactions are controlled by an electron transport chain, free electrons are not amongst the reactants or products in the three reactions shown and therefore do not affect the free energy released, which is used to pump protons (H ) into the intermembrane space. This process is efficient, but a small percentage of electrons may prematurely reduce oxygen, forming reactive oxygen species such as superoxide . This can cause oxidative stress in
27180-508: The relationship between yin and yang in Taoism , although the balance between yin and yang lacks the element of evil associated with the dark side. Taylor identifies other similarities between the Force and a Navajo prayer, prana , and qi .

27360-459: The same pattern-recognition receptors (PRRs) that respond to pathogen-associated molecular patterns (PAMPs) during infections. For example, mitochondrial mtDNA resembles bacterial DNA due to its lack of CpG methylation and can be detected by Toll-like receptor 9 and cGAS . Double-stranded RNA (dsRNA), produced due to bidirectional mitochondrial transcription, can activate viral sensing pathways through RIG-I-like receptors . Additionally,
27540-995: The same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells ). The multicellular animal Henneguya salminicola is known to have retained mitochondrion-related organelles despite a complete loss of their mitochondrial genome. A large number of unicellular organisms , such as microsporidia , parabasalids and diplomonads , have reduced or transformed their mitochondria into other structures, e.g. hydrogenosomes and mitosomes . The oxymonads Monocercomonoides , Streblomastix , and Blattamonas have completely lost their mitochondria. Mitochondria are commonly between 0.75 and 3 μm in cross section, but vary considerably in size and structure. Unless specifically stained , they are not visible. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling , cellular differentiation , and cell death , as well as maintaining control of
27720-448: The second film in the sequel trilogy, was released in 2017; Lucas described the film as "beautifully made".

28260-569: The sound and visual effects subdivisions of Lucasfilm, while Lucasfilm Games, later renamed LucasArts , produces products for the gaming industry. Having lost much of his fortune in a divorce settlement in 1987, Lucas was hesitant on making additional Star Wars features. However, the prequels , which were still only a series of ideas partially pulled from his original drafts of "The Star Wars", continued to tantalize him with technical possibilities that would make it worthwhile to revisit his older material. When Star Wars became popular once again, in
28440-458: The specific mechanisms between mitochondria and the cell cycle regulation is not well understood, studies have shown that low energy cell cycle checkpoints monitor the energy capability before committing to another round of cell division. Programmed cell death (PCD) is crucial for various physiological functions, including organ development and cellular homeostasis. It serves as an intrinsic mechanism to prevent malignant transformation and plays
28620-483: The story of Star Wars character Darth Vader in some ways, but concluded he was glad to be able to make his films the way he wanted to.

Wexler, later to work with Lucas on several occasions, was impressed by Lucas's talent. "George had
29160-409: The tissue's energy needs (e.g., in muscle ) are suddenly increased by activity. In the citric acid cycle, all the intermediates (e.g. citrate , iso-citrate , alpha-ketoglutarate , succinate, fumarate , malate and oxaloacetate) are regenerated during each turn of the cycle. Adding more of any of these intermediates to the mitochondrion therefore means that the additional amount is retained within
29340-470: The wake of Dark Horse 's comic book line and Timothy Zahn 's trilogy of spin-off novels , Lucas realized that there was still a large audience. His children were older, and with the explosion of CGI technology he began to consider directing once again.
