Metropolis (1927)

Metropolis is a 1927 German expressionist science-fiction silent 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 (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.[6] 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.
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, the city master. The film's message is encompassed in the final inter-title: "The Mediator Between the Head and the Hands Must Be the Heart".
