Looking for a way to create the character of Patrick Bateman, Christian Bale stumbled onto a Tom Cruise appearance on David Letterman. According to the director, Mary Harron, Bale saw in Cruise “this very intense friendliness with nothing behind the eyes” and Bale subsequently based the character of Bateman on that. Interestingly, Tom Cruise is actually featured in the novel; he lives in the same apartment complex as Bateman, who meets him in a lift and gets the name of Cocktail wrong, calling it “Bartender”.
