Oliver Yendell

Metropolis is a 1927 film about a futuristic city sharply divided between the working class and the city planners; the son of the city's mastermind falls in love with a working-class prophet who predicts the coming of a saviour to mediate their differences.

It is considered one of the first truly excellent science fiction films as it's said that the dystopian world paved the way for many new Si-Fi films such as blade runner and Brazil.

Metropolis employed vast sets, 25,000 extras and astonishing special effects to create two worlds: the great city of Metropolis, with its stadiums, skyscrapers and expressways in the sky, and the subterranean workers’ city, where the clock face shows 10 hours to cram another day into the work week.

The dystopian feel and the stylised look are a product of German expressionism, a movement emphasising the artist's inner feelings or ideas over replicating reality.

Overall, Fritz Lang's Metropolis can be considered the genesis of modern dystopian films as it conveyed Langs's feelings and directing style, which still can be found in many significant films.
