Metropolis

Metropolis is a 1927 German expressionist science-fiction drama film directed by Fritz Lang, and written by Thea von Harbou in collaboration with Lang from von Harbou's 1925 novel of the same name. Intentionally written as a treatment, it stars Gustav Fröhlich, Alfred Abel, Rudolf Klein-Rogge, and Brigitte Helm. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G. (UFA). The silent film is regarded as a pioneering science-fiction movie, being among the first feature-length movies of that genre. Filming took place over 17 months in 1925–26 at a cost of more than five million Reichsmarks, or the equivalent of about €21 million.
