The silent German film "Metropolis" (1926) features an above-ground elite and an underground city of factory workers. The workers are regimented, as this clip shows, and depicted as cogs in a great machine. By the time this film was made in the 1920s, large corporations were seen as economically dominant and the future of modern production. In effect, the film is a projection of concerns about the modern and coming era.
