Metropolis is a silent film directed by Fritz Lang. Set in a futuristic dystopian city, it tells the story of Freder, the son of the city's ruler, who falls in love with Maria, a prophet from the working class. The film explores themes of class struggle, love, and the quest for a mediator who can reconcile the divide.
Fritz Lang films the city as the divided economy: workers below, capital above. The Maria-robot is the genre's founding image; the film is the manifesto cinema kept rewriting.
Lang built a whole dystopian future out of shadow, scale and geometry — its city and its robot are still the visual DNA of science fiction.
