American Psycho is a film that is upfront about its inspiration. There are the obvious references in the title as well as the name of the name of the central character, Patrick Bateman, and the the thematic similarities confirm a degree of similarity. Psychological instability due to an erosion of identity is a key theme common to both films. However, being a comparatively new film, American Psycho had a much different feel to it. Bateman’s detached personality numbs the viewer to an abundance of shocking scenes that would not have survived 1960s censorship.
