Metropolis
"Metropolis is an epic 1927 German expressionist film directed by Fritz Lang and written by Lang and his wife, Thea von Harbou. Made in pre-WWII Germany, Metropolis is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city's ruler, and Maria, a poor worker, to overcome the vast gulf separating the classes of their city.
It is regarded as a pioneering work of the science-fiction genre in movies. Roger Ebert wrote that the time, place and characters created in Metropolis are ""so striking that they became part of our arsenal of images for imagining the world."" Metropolis is a major influence for Ridley Scott (Blade Runner), George Lucas (Star Wars), Tim Burton (Batman) and numerous other dystopian urban dramas."
