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’s ruler, and Maria, whose background is not fully explained in the film, to overcome the vast gulf separating the classist nature of their city. Metropolis was filmed in 1925, at a cost of approximately five million Reichsmarks. The film was met with a mixed response upon its initial release, with many critics praising its technical achievements while deriding its simplistic and naïve storyline. Due both to its long running-time and footage censors found questionable, Metropolis was cut substantially after its German premiere; large portions of the film were lost over the subsequent decades.
Numerous attempts have been made to restore the film since the 1970s-80s, and music producer Giorgio Moroder released a version with a soundtrack by rock artists such as Freddie Mercury and Adam Ant in 1984. A new reconstruction of Metropolis was shown at the Berlin Film Festival in 2001, and the film was inscribed on UNESCO's Memory of the World Register in the same year. In 2008, a print of Lang’s original cut of the film was found in a museum in Argentina. After a long restoration process, the restored film was shown on large screens in Berlin and Frankfurt simultaneously on 12 February 2010. (Wikipedia)
