Metropolis 1927

Possibly the first science fiction film ever made, Metropolis is surprisingly watchable for a film thats 87 years old. It tells the story of an upper class man who discovers the terrors of life in the undercity, which is where the energy to run the upper world is created. It features an evil Android and an enormous clock machine, both of which would fit in well with the most bonkers of modern scifi.This isnt actually a Hollywood film, but its influence on the dystopian subgenre is too big not to mention.
