For me the writing, when I'm going to direct it myself, is really just the first draft, and I don't change it very much; I only change it on average about two lines per movie. ↗
In a movie you have all these logistical problems; all these practical problems. But you're also going to have people come who can do things that you can't do, and you get to direct their talents. ↗
Those are fun, especially if they're going to shoot them in four weeks, because you know they're not going to mess with anything you do, so it can be very imaginative. ↗
