Fritz Lang's Metropolis, 1927
Metropolis presents the story of a future civilization from the point of view of 1926. The ruling class lives above ground in 'futuristic' towers; the working classes have been reduced to slavery living underground, working in underground factories, and gathering for secret meeting in the catacombs yet further underground. Here they are able to listen to Marie, the heroine, who likens the Metropolis to the
as she seeks to inspire the workers with hope for their future. Control of the city becomes a battle for the minds of the masses when the Master of Metropolis has his engineer kidnap Marie and construct a robot who looks like the heroine. The robot serves to lead the populace toward self-destruction even as Marie represents qualities that promise a human salvation. Towerof Babel
