Bale's American Psycho Inspiration: Tom Cruise

To capture the "Martian-like" behavior of serial killer Patrick Bateman in American Psycho, Christian Bale studied a fellow Hollywooder with a well-publicized belief in aliens, says director Mary Harron: Tom Cruise. Bale-as-Bateman looked at the world "like somebody from another planet," she tells BlackBook."One day he called me and he had been watching Cruise on David Letterman, and he just had this very intense friendliness with nothing behind the eyes, and he was really taken with this energy."
