Metropolis is a 1927 German expressionist epic science fiction drama film directed by Fritz Lang. The film was written by Lang and his wife Thea von Harbou, and starred Brigitte Helm, Gustav Fröhlich, Alfred Abel and Rudolf Klein-Rogge. A silent film, it was produced by Erich Pommer in the Babelsberg Studios by Universum Film A.G.. It is regarded as a pioneering work of science fiction genre in movies, being among the first feature length movies of the genre. 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, a poor worker, to overcome the vast gulf separating the classes of their city. Metropolis was filmed in 1925, at a cost of approximately five million Reichsmarks, making it the most expensive film ever released up to that point. The motion picture's futuristic style is influenced by the work of Futurist Italian architect, Antonio Sant'Elia. The film was met with a mixed response upon its initial release, with many critics praising its technical achievements and social metaphors while others derided its "simplistic and naïve" presentation.
