Do you know what moviemaking is? Eight hours of hard work each day to get three minutes of film. And during those eight hours there are maybe only ten or twelve minutes, if you’re lucky, of real creation. And maybe they don’t come. Then you have to gear yourself for another eight hours and pray you’re going to get your good ten minutes this time. Everything and everyone on a movie set must be attuned to finding those minutes of real creativity. You’ve got to keep the actors and yourself in a kind of enchanted circle. An outside presence, even a completely friendly one, is basically alien to the intimate process going on in front of him. Any time there’s an outsider on the set, we run the risk that part of the actors’ absorption, or the technicians’, or mine, is going to be impinged upon. It takes very little to destroy the delicate mood of total immersion in our work. We can’t risk losing those vital minutes of real creation. The few times I’ve made exceptions I’ve always regretted it.
