As a screenwriter I'm often writing in genres where there have been thousands of movies; whereas when I direct movies they tend to be in between genres. They tend to have a little bit of a genre to them, but they're really about the people, and they're people we haven't met before.
I don't write [screenplay character] biographies beforehand. I usually go in knowing some sequences: this is where I want to start, this is where I want to end.
If you write a movie for Roger Corman, it's going to get made. You saw it almost the next day.
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 certainly grew up seeing more movies and television than I read books, but when it came time to do the thing itself you don't have to hire a lot of people to sit down and write a book, so that was the story-telling medium that was available to me.
I remember being out here at the Sunset Marquis, and whoever knocked on the door, I would take that picture that I was writing and I would put that in the typewriter, so when I had the meeting, they would say: 'Oh, you're working on it right now?'
I never actually do rehearsals. That's one of the reasons that I write those bios and if I can meet with the actors I'll meet them or talk to them on the phone. What I want is for them to come on set knowing their lines and knowing who the character is.
But compared to writing a novel, where you can be God, I did the Bay of Pigs invasion in six pages once, and there were 50,000 guys with boots that I didn't have to pay, and all those extras; we didn't have to pay them.
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.
