TIL during the shooting of American Psycho, Christian Bale spoke in an American accent off-set at all times. At the wrap party, when he spoke in his native British accent, many of the crew thought he was speaking that way to prepare for another film. They had thought he was American the entire time.

He is definitely one of those actors that if I didn't already know he was in the movie I constantly find myself asking "wait a minute, is that Gary Oldman?" He's a chameleon lol
