"The talented actor needs craft. When you do a stage play, you do it once each night in chronological order. In a film you're going to wind up doing a scene 15-20 times, just by the nature of the process. If I tell you a joke once, it's funny. The more times I tell, the less funny it is. How do you get to the point where you can laugh again? You also may have to cry again and again."
