This paper aims to observe the aspect of the German expressionism shown in the film Metropolis by Fritz Lang from the angle of film history and discuss how it affected the science-fiction movie around Hollywood historically. This work has the value of research in that it gave a foundation to Hollywood science-fiction films of the U.S.A. with the other colleagues of the same field who went to America to flee from Hitler’s oppression. Especially, in this work, Lang provides the thematic consciousness to religiously sublimate the social ills made by the war and the industrial revolution of the German society in the late 1920s’. Above all, Lang must have tried to say that the industrialism produced the negative relationship between humans and machines which fact was naturally found out in the process to express his intention. Through the analysis, Metropolis presents a starting point to the traditional idea of these kinds of works always criticizing the American society having been dependent on machines in addition to being the first one of the long science-fiction movies in terms of time.
