We were just trying to make the films that we could get made, and to push the envelope. We didn't realize how far we had pushed the envelope. That all came later. That all came from books and articles about the golden age of the '70s. Believe me, to a lot of us, it was no golden age. The studio heads were very powerful then. They would fire guys right and left. They would look at your dailies and tell you what was wrong with them... a lot of stuff that doesn't go on today. Young filmmakers who are successful today, they don't often have that to put up with.

Technique is of less interest than character and story.

There are certain things that happen during the production of, I think, every film, that you didn't plan, and often it's better than what you did plan. There's the question of either going with it or not.

With all of my films that are on DVD and Blu-ray, I have spent weeks with them in a color timing room. Just changing or enhancing them. I have been desaturating the color. Sometimes I will make a scene bluer or redder. I do use the new medium. I believe in it.

In the case of a film like The Exorcist or To Live and Die in L.A., I saw the whole movie in my head before I went to shoot it. I never did storyboards, or anything like that. I had the film in my head.

When you go to a studio with something you want to make, or they come to you with something they want to make, more often than not, it's a tent pole. Not something one single person is really passionate about on a creative level.
