Restorations
The original premiere cut eventually disappeared, and a quarter of the original film was long believed to be lost forever.
In 1984, a new restoration and edit of the film was made by Giorgio Moroder. Moroder's version of the film was tinted throughout, featured additional special effects, subtitles instead of intertitles and a pop soundtrack featuring well-known singers, instead of a traditional score.
It was the first serious attempt made at restoring Metropolis to Lang's original vision, and until Kino's restoration in 2002 and 2010, it was the most complete version of the film in existence; the shorter run time was due to a faster frame rate than the original. In August 2011, after years of being unavailable on video in any format due to music licensing issues, it was announced that Kino International had managed to resolve the issues, and not only would the film be released on both Blu-Ray and DVD in November of that year, but it would also have a limited theatrical re-release.
The moderate commercial success of the Moroder version of the film inspired Enno Patalas to make an exhaustive attempt to restore the movie in 1986. This version was the most accurate reconstruction until that time, being based on the film’s script and musical score. The basis of Patalas' work was a copy in the Museum of Modern Art's collection.
In conjunction with Kino International, Metropolis’s current copyright holder, the F.W. Murnau Foundation released a digitally restored version of the film in 2002. This edition included the film’s original music score and title cards that described the events featured in missing sequences. Previously unknown sections of the film were discovered in film museums and archives around the world, and the footage was digitally cleaned and repaired to remove defects.
In 2005, Wollongong-based historian and politician Michael Organ had examined a print of the film in the National Film Archive of New Zealand. Organ discovered that the print contained scenes missing from other copies of the film. After hearing of the discovery of the Argentine print of the film and the restoration project currently under way, Organ contacted the German restorers about his find. The New Zealand print contained eleven missing scenes and featured some brief pieces of footage that were used to restore damaged sections of the Argentine print. It is believed that the Australian, New Zealand and Argentine prints were all scored from the same master. The newly discovered footage was used in the restoration project.
On 1 July 2008, film experts in Berlin announced that a 16 mm reduction negative of the original cut of the film had been discovered in the archives of the Museo del Cine in Buenos Aires, Argentina. The print had been in circulation since 1928, starting off with a film distributor and subsequently being passed to a private collector, an art foundation and finally the Museo del Cine. The print was investigated by the museum’s curator after he heard an anecdote from a cinema club manager expressing surprise at the length of a print of Metropolis he had viewed. The print was in poor condition and required considerable restoration before it was re-premiered in February 2010. Two short sequences from the film, depicting a monk preaching in the cathedral and a fight between Rotwang and Fredersen, were in extremely poor condition and could not be salvaged.
