When I'm directing a great dramatic scene, part of me is saying, "Thank God I don't have to do that." Because I know how fucking hard it is to act. It's the middle of the night. It's freezing. You gotta do this scene. You gotta get it up to get to that point. And yet, as a director, you've got to get the actors to that point. It's hard either way.
