Compare The Great Gatsby to the movie The Usual Suspects.
I would start off with the idea of concealing one's identity from others. Gatz reinvents himself as Gatsby. Soze reinvents himself as Verbal Kint. In the end, both transformations are done to prove to society something only known to the individual. The idea that we, as human beings, reinvent ourselves for others and to others is one level of comparison between both works. Another level of comparison present is that there is little in way of social cohesion or authentic communitarian bonds present. Both works depict individuals who are concerned about their own well being and any attempts and communitarianism are undercut by such a reality. For example, the "Flappers" like Jordan and Toma and Daisy are more concerned with a good party and enjoying themselves as opposed to actually forming socially productive connections that make the world better. This self interest is the same with that band of individuals in the film, men who are only concerned with either acquiring more wealth or getting out of the debt owed to Soze. In both, there is little hope for community when such self interest overrides all.
