I don’t have a quote in my pocket but I’ve read interviews with Christopher Walken where he says that his job is to be an actor so if someone wants to cut him a paycheck to act, he’ll do it. Got a movie about cartoon bears or ping-pong or hip-hop kangaroos? It ain’t his job to judge, it’s his job to act.
I remember reading a review about the stinker “Meet Joe Black” back when Brad Pitt wasn’t a megastar yet. The reviewer was pretty sure that he would have several more shots at making it big because “He’s too handsome not to”.
