Home to a futuristic society, Fritz Lang's Metropolis (1927) features a city where society has been physically divided to achieve perfection. According to Norden “With its motifs and representation of workers as machine-like automatons (they even move mechanically), 'Metropolis' unmistakably bears the mark of futurism” (Norden 109). This society is divided into two classes: the thinkers, who are the wealthy rulers of the city, and the workers, who literally work underground to provide for the city. Living in opulence, the audience is introduced to the city's ruler Johann 'Joh' Fredersen (Alfred Abel) and his son Freder Frederson (Gustav Fröhlich). One day, while indulging in his wealth at the Pleasure Garden, Freder sees a beautiful woman named Maria (Brigitte Helm). Freder becomes infatuated with Maria and decides to follow her to the underworld where the workers are. Freder quickly discovers that Maria is part of the working class and that she has called for unity between the workers and the rulers of Metropolis. Enchanted by the cause, Freder tries to help the workers, but his father discovers the plan and tries to sabotage it. To avoid the destruction of the narrowly constructed social classes, Joh teams up with an old colleague and nemesis, Rotwang (Rudolf Klein-Rogge). Together, Rotwang and Joh imprison the real Maria and develop a robotic version of Maria that encourages the workers to rebel against their ruler. The film ends with a climactic scene in which Freder, in an attempt to save the real Maria from Rotwang, pushes Rotwang off the roof of a cathedral where he falls to his death. Freder then returns to the city where he is finally able to unite the workers with the rulers, serving his purpose... middle of paper... where the workers carry out their tasks. The scene alternates with a subdued shot of the workers marching as if they were soldiers. Quickly, the scene changes to a reaction shot of Freder's worried face as he notices one of the workers wearily working on the town's Heart Machine. Freder approaches the man he calls "Brother" and, exhausted, the man falls into Freder's arms. The man tries to free himself from Freder's hands and then there is a mid-shot of the worker agitatedly stating to Freder that someone needs to stay on the machine. Seeing the level of distress the worker was in, Freder agrees to work on the machine. The shot then dissolves into a caption in which Freder tells the worker “Listen to me… I want to trade lives with you!”. The scene ends at the 31:22 mark with a mid-shot of Freder working on the city's Heart Machine.
