 Many critics see a direct tie between cinema and architecture of the time, stating that the sets and scene artwork of Expressionist films often reveal buildings of sharp angles, great heights, and crowded environments, such as the frequently shown Tower of Babel in Fritz Lang's "Metropolis".Strong elements of monumentalism and modernism appear throughout the canon of German Expressionism.An excellent example of this is "Metropolis", as evidenced by the enormous power plant and glimpses of the massive yet pristine "upper" city.
