Metropolis

Read Metropolis Storyline:

This is Metropolis, the novel that the film's screenwriter -- Thea von Harbou, who was director Fritz Lang's wife, and a collaborator in the creation of the film -- this is the novel that Harbou wrote from her own notes. It contains bits of the story that got lost on the cutting-room floor; in a very real way it is the only way to understand the film.
