Opel-RAK were a series of rocket vehicles produced by German automobile manufacturer Fritz von Opel , of the Opel car company, in association with others, including Max Valier , Julius Hatry , and Friedrich Wilhelm Sander . Opel RAK is generally considered the world's first large-scale rocket program, significantly advancing rocket and aviation technology as well as instrumental in popularizing rockets as means of propulsion. In addition Opel RAK demonstrations were also highly successful as publicity stunts for the Opel car company. The Lippisch Ente (meaning “duck” in German), the world's first rocket-powered glider and piloted for its first flight on June 11, 1928, by Fritz Stamer at Wasserkuppe , was bought and operated by Opel in context of the Opel RAK program but is not formally designated an Opel RAK series number. Also a rocket-powered RAK-Motoclub motorbike, based on a conventional Opel Motoclub 500 SS and presented at the Berlin Motorshow 1928, did not receive a formal RAK number.

115-534: The idea to build and race a rocket-powered car was suggested to von Opel by Max Valier. After the war, Valier became highly interested in rocketry. Valier, in 1927, became one of the founders of the German Verein für Raumschiffahrt , or “Spaceflight Society,” a group of later highly influential scientists who would play a major role in making rocket spaceflight a reality. Valier was more interested in publicizing rocketry than marketing Opel automobiles but came to

230-565: A German nationalist businessman, cancelled UFA's debt to Paramount and Metro-Goldwyn-Mayer after taking charge of the company in April 1927, and chose to halt distribution in German cinemas of Metropolis in its original form. Hugenberg had the film cut down to a length of 3,241 metres (about 118 minutes), broadly along the lines of Pollock's edit, removing the film's perceived "inappropriate" communist subtext and religious imagery. Hugenberg's cut of

345-407: A novel of the same title written by Harbou for the sole purpose of being made into a film. The novel in turn drew inspiration from H. G. Wells , Mary Shelley and Villiers de l'Isle-Adam 's works and other German dramas. The novel featured strongly in the film's marketing campaign, and was serialized in the journal Illustriertes Blatt in the run-up to its release. Harbou and Lang collaborated on

460-563: A 5-km stretch of straight track near Hanover. Some 20,000 spectators watched RAK 3 breaking the existing world speed record of railcars by nearly 40 km/h. The resulting international publicity after RAK2 and RAK3 demonstrations was enormous and gave the science of rocketry a major boost. A replica of the RAK 2 rocket-propelled car is on display at the Opel museum in Rüsselsheim , another one at

Friedrich Wilhelm Sander Friedrich Wilhelm Sander (25 August 1885 in Glatz (Kłodzko) – 15 September 1938) was a German pyrotechnics and rocket technology engineer as well as manufacturer remembered for his contributions to rocket-powered flight as key protagonist of the Opel-RAK program. Sander was the son of a professional soldier. He went to school in Uslar on

690-526: A cost of more than five million Reichsmarks , or the equivalent of about €21 million. Made in Germany during the Weimar period , Metropolis is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city master, and Maria, a saintly figure to the workers, to overcome the vast gulf separating the classes in their city and bring the workers together with Joh Fredersen,

805-415: A costume that would both appear metallic and allow a small amount of free movement. Helm sustained cuts and bruises while in character as the robot, as the costume was rigid and uncomfortable. Gottfried Huppertz composed the film's score for a large orchestra. He drew inspiration from Richard Wagner and Richard Strauss , and combined a classical orchestral style with mild modernist touches to portray

920-467: A half times the original budget. Producer Erich Pommer had been fired during production. The effects expert Eugen Schüfftan created pioneering visual effects for Metropolis . Among the effects used are miniatures of the city, a camera on a swing, and most notably, the Schüfftan process , in which mirrors are used to create the illusion that actors are occupying miniature sets. This new technique

1035-582: A kind of wooden armament, and because the shot took so long, I didn't get enough air." Despite the hardships, Thea von Harbou recounted how the film set was paradise for the hundreds of poor, malnourished children used as extras. In 1927 in Metropolis Magazine , von Harbou describes their warm and clean rooms, time for play, and ample toys and hot meals four times a day. "No film ever had more enthusiastic and willing collaborators than these little children," she recalled, "always willing to dash into

1150-417: A large crowd assembled outside of Frankfurt, the intrepid von Opel made a successful flight of almost 3.5 km in 75 seconds, reaching an estimated top speed of around 150 km/h. RAK.1 made a hard landing, but it had made an emphatic point about rocket aviation and popularized rockets as means of propulsion immensely, causing a so-called global "rocket rumble". The aircraft is sometimes also referred to as

1265-551: A larger, two-story factory building at Fährstrasse No. 26 as a prerequisite for accepting development contracts offered by the Navy. In 1928, he was approached by Max Valier , on behalf of Fritz von Opel to provide rockets to propel cars and aircraft as a means of popularizing the use of rockets for propulsion and for promoting the Opel company. Their joint projects within Opel-RAK , the world's first large-scale rocket program, involved

1610-732: A luxurious backdrop, suspended in the dark sky to dazzle, distract and hypnotize". He added "The sight of Neuyork [sic] alone should be enough to turn this beacon of beauty into the center of a film..." The appearance of the city in Metropolis is strongly informed by the Art Deco movement; however, it also incorporates elements from other traditions. Ingeborg Hoesterey described the architecture featured in Metropolis as eclectic, writing how its locales represent both "functionalist modernism [and] art deco" whilst also featuring "the scientist's archaic little house with its high-powered laboratory,

Schaberger supervised all the details involved in construction and assembly (of rocket cars), and every time I sat behind the wheel with a few hundred pounds of explosives in my rear, and made the first contact, I did so with a feeling of total security [...] As early as 1928, Mr. Schaberger and I developed a liquid rocket, which was definitely the first permanently operating rocket in which

2070-549: A second unit was ready to go, Sander tied a 4,000-meter-long rope to the rocket. After 2000 m of rope had been unwound, the line broke and this rocket also disappeared in the area, probably near the Opel proving ground and racetrack in Rüsselsheim, the "Rennbahn". The main purpose of these tests was to develop the propulsion system for the aircraft for crossing the English channel. Therefore, the flights of these two (compared to

2185-486: A speech on the donation of a RAK 2 replica to the Deutsches Museum, von Opel mentioned also Opel engineer Josef Schaberger as a key collaborator.

2300-407: A trance, enthusiastic and enraptured at the same time—I can't forget the incredible strain that they put us under. The work wasn't easy, and the authenticity in the portrayal ended up testing our nerves now and then. For instance, it wasn't fun at all when Grot drags me by the hair, to have me burned at the stake. Once I even fainted: during the transformation scene, Maria, as the android, is clamped in

2415-508: A tremendous influence on Lippisch, whose experience with the rocket-powered "Ente" eventually paved the way to the Messerschmitt Me-163 , the first operational rocket fighter craft. The Opel RAK experiments excited also the interest of the German military, which provided funding for further development of rockets as a replacement for artillery. This led to an array of military applications, among them Germany's V-2 terror weapon,

7475-446: The family's real-estate business. The impact of Opel RAK was both immediate and long-lasting on later spaceflight pioneers. Opel, Sander, Valier and Hatry had engaged in a program that led directly to use of jet-assisted takeoff for heavily laden aircraft. The German Reich was first to test the approach in August 1929 when a battery of solid rocket propellants supported a Junkers Ju-33 seaplane to get airborne. The Opel RAK experiments had

7935-490: The film takes place in 3000. A note in one edition of Harbou's novel says that the story does not take place at any particular place or time, in the past or the future. Meanwhile, the 1963 Ace Books edition, which is a reprint of the 1927 English edition, specifies the setting as "The World of 2026 A.D.". On 22 May 1925, Metropolis began principal photography with an initial budget of 1.5 million ℛ︁ℳ︁. Lang cast two unknowns with little film experience in

8050-477: The film was found in a museum in Argentina. According to the explanation in the restored film, "the material was heavily damaged and, because it had been printed on 16mm film stock, does not have the full-aperture silent picture ratio" and "in order to maintain the scale of the restored footage, the missing portion of the frame appears black" while "black frames indicate points at which footage is still lost". After

8165-491: The film was inscribed on UNESCO 's Memory of the World Register , the first film thus distinguished. On 1 January 2023, the film's American reserved copyright expired, thereby entering the film into the public domain . In the future, wealthy industrialists and business magnates and their top employees reign over the city of Metropolis from colossal skyscrapers, while underground-dwelling workers toil to operate

8280-475: The film was released in German cinemas in August 1927. Later, after demands for more cuts by Nazi censors , UFA distributed a still shorter version of the film (2,530 metres, 91 minutes) in 1936, and an English version of this cut was archived in the Museum of Modern Art (MoMA) film library in the 1930s. It was this version which was the basis of all versions of Metropolis until the recent restorations. In 1986 it

8395-443: The film's massive industrial city of workers. Nestled within the original score were quotations of Claude Joseph Rouget de Lisle 's " La Marseillaise " and the traditional " Dies Irae ", the latter of which was matched to the film's apocalyptic imagery. Huppertz's music played a prominent role during the film's production; the composer often played piano on Lang's set to inform the actors' performances. Huppertz's score only accompanied

8510-406: The financing, the theoretical knowledge, and the practical capability necessary for success. Moreover, von Opel, Valier, and Sander said from the start that their experiments with cars were only a prelude to grander experiments with air- and spacecraft: They agreed on the final goal of working on rocket-powered aircraft at the same time they were building their famous rocket cars, as pre-condition for

8625-403: The first contact, I did so with a feeling of total security [...] As early as 1928, Mr. Schaberger and I developed a liquid rocket, which was definitely the first permanently operating rocket in which the explosive was injected into the combustion chamber and simultaneously cooled using pumps. [...] We used benzol as the fuel," von Opel continued, "and nitrogen tetroxide as the oxidizer. This rocket

8740-412: The great machines that power it. Joh Fredersen is the city's master. His son, Freder, idles away his time at sports and in a pleasure garden, but is interrupted by the arrival of a young woman named Maria, who has brought a group of workers' children to witness the lifestyle of their rich "brothers". Maria and the children are ushered away, but Freder becomes fascinated by her. Against the strict rules of

8855-487: The launch of two experimental liquid-fuel rockets by Sander on April 10 and 12, 1929. In the preface of his book “Raketenfahrt” he describes the size of the rockets as of 21 cm in diameter and with a length of 74 cm, weighing 7 kg empty and 16 kg with fuel. The maximum thrust was 45 to 50 kp, with a total burning time of 132 seconds. These properties indicate a gas pressure pumping. The first missile rose so quickly that Sander lost sight of it. Two days later,

8970-462: The lead roles. Gustav Fröhlich (Freder) had worked in vaudeville and was originally employed as an extra on Metropolis before Thea von Harbou recommended him to Lang. Brigitte Helm (Maria) had been given a screen test by Lang after he met her on the set of Die Nibelungen , but would make her feature film debut with Metropolis . In the role of Joh Fredersen, Lang cast Alfred Abel, a noted stage and screen actor whom he had worked with on Dr. Mabuse

9085-405: The machine halls, assuming the identity of an ill worker. Fredersen takes the maps to the city's greatest inventor, Rotwang , to learn their meaning. Rotwang had been in love with a woman named Hel, who left him to marry Fredersen and later died giving birth to Freder. Rotwang shows Fredersen a robot he has built to " resurrect " Hel. The maps show a network of catacombs beneath Metropolis, and

9200-501: The military, so it was expropriated and all documents were confiscated. After three months in custody, Sander was released, only to be arrested again in November 1935. After a year in custody, he was sentenced to four and a half years in prison and a fine for treason. Sander had also sold his missiles to Italy and England. Since these were older versions of his powder rockets, he did not consider this to be forbidden. Sander speculated that

9315-640: The original film that it was "symbolism run such riot that people who saw it couldn't tell what the picture was about. ... I have given it my meaning." Lang's response to the re-editing of the film was to say "I love films, so I shall never go to America. Their experts have slashed my best film, Metropolis , so cruelly that I dare not see it while I am in England." The Hel storyline would be partially restored in Giorgio Moroder 's 1984 version, and subsequent versions completely restored it. In Pollock's cut,

9430-460: The plot as "laid on with a terrible Teutonic heaviness, and an unnecessary amount of philosophizing in the beginning" that made the film "as soulless as the city of its tale". He also called the acting "uninspired with the exception of Brigitte Helm". Nevertheless, Claxton wrote that "the setting, the use of people and their movement, and various bits of action stand out as extraordinary and make it nearly an obligatory picture." Other critics considered

9545-436: The poorest districts of Berlin had to work for 14 days in a pool of water that Lang intentionally kept at a low temperature. Lang would frequently demand numerous re-takes, and took two days to shoot a simple scene where Freder collapses at Maria's feet; by the time Lang was satisfied with the footage he had shot, actor Gustav Fröhlich found he could barely stand. Other anecdotes involve Lang's insistence on using real fire for

9660-414: The premiere was met with muted applause interspersed with boos and hisses. At the time of its German premiere, Metropolis had a length of 4,189 metres, which is approximately 153 minutes at 24 frames per second (fps). UFA's distribution deal with Paramount and MGM "entitled [them] to make any change [to films produced by UFA] they found appropriate to ensure profitability". Considering that Metropolis

9775-562: The press on April 11, 1928, in Rüsselsheim was arranged: Opel engineer and race driver Kurt C. Volkhart developed and tested the Opel-RAK 1, a converted racing car equipped with Sander rockets instead of an internal combustion engine, was the first rocket powered automobile. During the April 1928 experimentations RAK 1 reached, piloted by Volkhart, the symbolic speed of 100 km/h in just eight seconds. Von Opel, Sander and Valier were satisfied by RAK 1's performance, and in particular by

9890-415: The rockets exploded, punching holes in both wings and setting the aircraft alight. Stamer was nevertheless able to bring it down from a height of around 20 metres (65 ft) before hastily abandoning the Ente, which was burned beyond any hope of salvage. Despite the loss of the first rocket plane, von Opel immediately contracted with Julius Hatry for a specialized rocket aircraft. Hatry's design for Opel

10005-485: The same 1924 trip also influenced the film in another way: Lang and producer Erich Pommer realized that to compete with the vertical integration of Hollywood, their next film would have to be bigger, broader, and better made than anything they had made before. Despite UFA's growing debt, Lang announced that Metropolis would be "the costliest and most ambitious picture ever." The film drew heavily on biblical sources for several of its key set-pieces. During her first talk to

10120-451: The same enthusiasm as Sander to our small secret group, one of the tasks of which was to hide all the preparations from my father, because his paternal apprehensions led him to believe that I was cut out for something better than being a rocket researchist. Schaberger supervised all the details involved in construction and assembly (of rocket cars), and every time I sat behind the wheel with a few hundred pounds of explosives in my rear, and made

10235-477: The same name (which was intentionally written as a treatment ). It stars Gustav Fröhlich , Alfred Abel , Rudolf Klein-Rogge , and Brigitte Helm . Erich Pommer produced it in the Babelsberg Studio for Universum Film A.G. (UFA). Metropolis is regarded as a pioneering science-fiction film, being among the first feature-length ones of that genre. Filming took place over 17 months in 1925–26 at

10350-404: The screenplay derived from the novel, and several plot points and thematic elements—including most of the references to magic and occultism present in the novel—were dropped. The screenplay itself went through many rewrites, and at one point featured an ending where Freder flew to the stars; this plot element later became the basis for Lang's Woman in the Moon . The time setting of Metropolis

10465-457: The senior boss Wilhelm von Opel felt disturbed by the engine noise and wanted to stop this new “dangerous madness” of his son. From 1930, Sander (with other pyrotechnics factories) began secretly manufacturing rockets for military purposes, at the direction of Walter Dornberger . Without warning, Sander was arrested by the Gestapo on 31 January 1935. His company was subordinated to a trustee of

10580-489: The skyscrapers in New York in October 1924". He had visited New York City for the first time and remarked "I looked into the streets—the glaring lights and the tall buildings—and there I conceived Metropolis ," although in actuality Lang and Harbou had been at work on the idea for over a year. Describing his first impressions of the city, Lang said that "the buildings seemed to be a vertical sail, scintillating and very light,

10695-732: The southwestern edge of the Solling and then learned to be a mechanical engineer. At the Technikum Strelitz in Altstrelitz in Mecklenburg he became an engineer around 1908/09. In 1909 Sander moved to Bremerhaven. Here he worked in various areas. In 1920 he took over the company of master gunsmith H. G. Cordes in Bremerhaven , who had existed from 1853 and was known as the inventor of the whaling cannon. Sander soon expanded

10810-401: The street, and Rotwang falls to his death. Freder fulfills his destiny to unite the city and the underworld by linking the hands of Fredersen and Grot to bring them together. Metropolis features a range of elaborate special effects and set designs, ranging from a huge gothic cathedral to a futuristic cityscape. In an interview, Fritz Lang reported that "the film was born from my first sight of

10925-589: The tarpaulin off the Opel RAK 2 and carefully pushed it to the start. Eventually the rockets were installed and connected to the ignition mechanism. Police cleared the AVUS track and von Opel drove the RAK 2 car to a record-setting speed of 238 km/h, successfully mastering the challenge of insufficient downforce from the wings for these velocities. The RAK 2 rockets were operational for a ride of circa three minutes, watched by 3000 spectators and world media, among them Fritz Lang , director of Metropolis and Woman in

11040-428: The two men go to investigate. They eavesdrop on a gathering of workers, including Freder. Maria addresses them, prophesying the arrival of a mediator who can bring the working and ruling classes together. Freder believes he can fill the role and declares his love for Maria. Fredersen orders Rotwang to give Maria's likeness to the robot so that it can discredit her among the workers but is unaware that Rotwang's true plan

11155-685: The work at the Traverse City Film Festival in Traverse City, Michigan in August 2009. For the film's 2010 "complete" restoration premiere, Huppertz's score was performed live and subsequently re-recorded by the Berlin Radio Symphony Orchestra , conducted by Frank Strobel . This version was released internationally on various DVD and Blu-ray editions beginning in 2010. Various artists have created other scores for Metropolis : Metropolis

11270-641: The workers, Maria uses the story of the Tower of Babel to highlight the discord between the intellectuals and the workers. Additionally, a delusional Freder imagines the false-Maria as the Whore of Babylon , riding on the back of a many-headed dragon. The name of the Yoshiwara club alludes to the famous red-light district of Tokyo. Much of the plot line of Metropolis stems from the First World War and

11385-705: The world's first ballistic missile. After World War II, these German rocket and missile scientists and engineers would have an immense impact on missile and space programs by the United States of America. Walter J. Boyne , Director of the National Air and Space Museum in Washington, DC, concluded "Working together, von Opel, Valier, and Sander had thrown a big rock of publicity into the mill pond of science. The ripples have not yet ceased to spread." The 1937 German film Weltraum Schiff I Startet Eine Technische Fantasie has short clips of various RAK vehicles: 11 seconds at 436 feet (approximately 04:47) igniters being wired to

11500-438: Was 45 to 50 kp, with a total burning time of 132 seconds. These properties indicate a gas pressure pumping. The first missile rose so quickly that Sander lost sight of it. Two days later, a second unit was ready to go, Sander tied a 4,000-meter-long rope to the rocket. After 2000 m of rope had been unwound, the line broke and this rocket also disappeared in the area, probably near the Opel proving ground and racetrack in Rüsselsheim,

11615-429: Was Mrs. Von Harbou's, but I am at least 50 percent responsible because I did it. I was not so politically minded in those days as I am now. You cannot make a social-conscious picture in which you say that the intermediary between the hand and the brain is the heart. I mean, that's a fairy tale—definitely. But I was very interested in machines. Anyway, I didn't like the picture—thought it was silly and stupid—then, when I saw

11730-501: Was buying the machines' output if not the workers, and found parts of the story derivative of Shelley's Frankenstein , Karel Čapek 's R.U.R. , and his own The Sleeper Awakes . Wells called Metropolis "quite the silliest film", but the New York Herald Tribune called it "a weird and fascinating picture". In The New Yorker Oliver Claxton called Metropolis "unconvincing and overlong", faulting much of

11845-493: Was cut substantially after its German premiere. Many attempts have been made since the 1970s to restore the film. In 1984, Italian music producer Giorgio Moroder released a truncated version with a soundtrack by rock artists including Freddie Mercury , Loverboy , and Adam Ant . In 2001, a new reconstruction of Metropolis was shown at the Berlin Film Festival . In 2008, a damaged print of Lang's original cut of

11960-692: Was distributed by Parufamet , a company formed in December 1925 by the American film studios Paramount Pictures and Metro Goldwyn Mayer to loan US$ 4 million to UFA. The film had its world premiere at the UFA-Palast am Zoo in Berlin on 10 January 1927, where the audience, including a critic from the Berliner Morgenpost , reacted to several of the film's most spectacular scenes with "spontaneous applause". However, others have suggested

12075-647: Was far larger and more streamlined than its predecessor. The RAK 2 was powered by 24 rockets packing 264 pounds of explosives. On May 23, 1928, Fritz von Opel himself demonstrated the car, Opel RAK 2, on the Avus Speedway near Berlin . Prior to the start Professor Johann Schütte, Chairman of the Scientific Society of Aviation, and Fritz von Opel held prophetic speeches on the future of rocket-based aviation and spaceflight. After these introductory remarks, mechanics August Becker and Karl Treber then took

12190-588: Was impressed with the film's message of social justice. In a 1928 speech, he said, "the political bourgeoisie is about to leave the stage of history. In its place advance the oppressed producers of the head and hand, the forces of Labor, to begin their historical mission". Shortly after the Nazis came to power, Goebbels told Lang that, on the basis of their seeing Metropolis together years before, Hitler had said that he wanted Lang to make Nazi films. German cultural critic Siegfried Kracauer later wrote of Metropolis , "The Americans relished its technical excellence;

12305-415: Was imprisoned for treason by the Nazis and forced to sell his business, he died in custody 1938. Hatry tried to continue the work on his aircraft developments, but was sidelined by the Nazis since he had a Jewish grandfather. He had to start anew and became a screenwriter and documentary filmmaker. Hatry was drawn into theater and fiction, finally his mother convinced him after his father's death to take over

12420-429: Was installed in a Mueller-Griessheim aircraft and developed a thrust of 70 kg (154 lb.)." By May 1929, the engine produced a thrust of 200 kg (440 lb.) "for longer than fifteen minutes and in July 1929, the Opel RAK collaborators were able to attain powered phases of more than thirty minutes for thrusts of 300 kg (660-lb.) at Opel's works in Rüsselsheim," according to Max Valier's account. Max Valier also reports

12535-484: Was made." Leonard Maltin's Movie Guide 's entry on the film reads, "Heavy going at times but startling set design and special effects command attention throughout." Colin Greenland reviewed Metropolis for Imagine magazine, and stated that "It's a measure of the sheer power of Lang's vision that it survives this heavy-handed cosmetic modernizing quite intact. Inspired by his first sight of Manhattan, Metropolis

12650-451: Was positively overwhelming and that there were some exceptional performances. Critic Mordaunt Hall of The New York Times called it a "technical marvel with feet of clay". A review by H. G. Wells dated 17 April 1927 accused it of "foolishness, cliché, platitude, and muddlement about mechanical progress and progress in general". He faulted Metropolis for its premise that automation created drudgery rather than relieving it, wondered who

12765-442: Was rather more elegant than the Ente. With a wingspan of 36 feet and length of 16 feet, the new aircraft Opel RAK.1 had a typical sailplane wing , under which a pod was suspended to accommodate the pilot and sixteen of Sander's solid rocket engines each with 50 pounds of thrust. The tailplane was mounted on booms behind the wing and high out of the way of the rocket exhaust. The first public flight came on Sept. 30, 1929. Before

12880-418: Was recopied and returned to Germany to be the basis of the 1987 Munich Archive restoration . Despite the film's later reputation, some contemporary critics panned it. Variety 's first review of the film in Berlin considered the scenario to be weak and felt that the artistic work had been wasted on the manufactured story although did acknowledge that nothing had been filmed like it before and its effect

12995-535: Was seen again just two years later in Alfred Hitchcock 's film Blackmail (1929). The Maschinenmensch – the robot built by Rotwang to resurrect his lost love Hel – was created by sculptor Walter Schulze-Mittendorff. A whole-body plaster cast was taken of actress Brigitte Helm, and the costume was then constructed around it. A chance discovery of a sample of "plastic wood" (a pliable substance designed as wood-filler) allowed Schulze-Mittendorff to build

13110-532: Was set to adjust the aircraft's center of gravity as the rocket fuel was consumed. An elastic launching rope was used to catapult the Ente into the air. After one false start, the aircraft took off and flew a 1,500 metre (4,900 ft) circuit of the Wasserkuppe's landing strip. On the second flight, the team decided to try firing both rockets together for increased thrust over a shorter period. Something went wrong, however, and rather than burning properly, one of

13225-453: Was too long and unwieldy, Parufamet commissioned American playwright Channing Pollock to write a simpler version of the film that could be assembled using the existing material. Pollock shortened the film dramatically, altered its inter-titles and removed all references to the character of Hel, because the name sounded too similar to the English word Hell , thereby removing Rotwang's original motivation for creating his robot. Pollock said about
