I don't want to take shots at professional actors, because obviously the great ones are great. But I do think that given the kind of stories I've been telling in my films, it's hard for me to imagine how professional actors would have done better. And it's easy for me to imagine how they would have done worse. Because I think a lot of what an actor is trained to do and a lot of what an actor's instincts point toward is clarification, is always making it clear what's happening in the story, how the character fits into the scene, what the character wants.
