• Because of the way that I work with the actors and because a scene is not in this rigid and literal interpretation of something written, I can constantly change stuff, which means I can get a scene absolutely perfect, and then when we go to shoot it, the requirements of the shot mean it would be useful to extend the dialogue or take a line out or swap things around. So the camera doesn't serve the action. The action serves the camera. That's important. So it becomes more and more organic and integrated.
