I think I got spoiled and that writing a short story and getting it published, or writing a novel and getting it published, you pretty much get to do the first, second and third draft yourself without a whole lot of interference.
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.
I once read Updike after writing a first draft, and I wanted to put my own book on the fire. I've since learned to read utter crap while I'm writing: pulp is the thing.
Some people like to purge out a draft and just let it go and then go back and fix it, but I'm a writer-rewriter. I can't move on until I feel like it's presentable.
I write very quickly; I rewrite very slowly. It takes me nearly as long to rewrite a book as it does to get the first draft. I can write more quickly than I can read.
In my office in Florida I have, I think, 30 manuscript piles around the room. Some are screenplays or comic books or graphic novels. Some are almost done. Some I'm rewriting. If I'm working with a co-writer, they'll usually write the first draft. And then I write subsequent drafts.
When you have a performer as talented as Bill Murray or as Harold, that can write as well as they can perform, you can do a final draft on the set if you think of it that way.
I write until the first draft is finished, and then I feel that I can get out. But, during the time of the writing of the first draft, I don't go out. I'm just locked away, writing. It's a time of meditation, of going into the story.
Back then I said to myself 'screw football.' Actually I just took part in this camp as there was nothing better for me to do. They also didn't draft me because they thought I was too wild and undisciplined.
