Patrick Babeman.

In 2000, director Mary Harron adapted Bret Easton Ellis's controversial third novel American Psycho (1991) to the screen, starring Christian Bale as the 27-year-old yuppie/serial killer Patrick Bateman. Like the novel, the film American Psycho can be seen as an ultimate portrayal of the 1980s New York yuppie lifestyle, depicting a world dominated by hedonism, greed, and egocentrism. The novel's long enumerations of brand name consumer goods, denoting the fashion-dictated materialism that constitutes yuppie life, have been translated cinematically into a sterile space of (now extremely dated) 1980s designer goods. The film version anatomizes the construction of Bateman's double identity that in the novel is created through the use of an unreliable narrator, the appropriation of pop cultural products (particularly brand names, pop songs, and the images of horror and porn movies), and the use of "cinematic" techniques of narration.
