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.

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.

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.

If you write a movie for Roger Corman, it's going to get made. You saw it almost the next day.

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.
