Surely this should be films that are close in terms of subject matter and stylistic imagery? They both share a few traits but Taxi Driver V Light Sleeper would be more apt. Both written by Paul Schrader and both deal with characters on the edge of society. In fact Schrader has said that Taxi Driver is a character in his 20's, American Gigolo is the same character but in his 30's without the back story and Light Sleeper is the same character but in his 40's. Light Sleeper is an absolute gem. Shame more people don't know about it
