In order to achieve a result on a film like The Exorcist, I’ve got to coordinate the efforts of these eighty-five people every morning, and every one of these people comes in with special problems and hangups, and none of them are getting paid as much as I am, and none of them will get as much credit. Yet, all of this is unspoken between us, and we come together because we love the work. These are people who contribute to movies, guys whose names you’ll never know, they’ll come up and say “why don’t we do this shot from here?” and by God, they’ll be right.
