Fritz Lang's Metropolis is a movie about the future that debuted in 1927. Often shown in architecture school, the movie depicts an urban utopia where the residents live a carefree life unaware of the dark underworld of common folk who keep the Metropolis running. The story is a classic rendition of the separation of societal classes.
Architects enjoy the film's visual style and "effects." This is a classic work that should be in every architect's movie collection.
