I don't like to be in front of the camera - my place is behind the camera.

Jack [Nicholson] really knows about the camera. He's one of the directors who likes to play with the camera. He'll change things around, play with lighting, things like that. He'll even spend hours on the set-up for an insert shot. He's an interested person who gets involved in all the aspects of the films he is making.

You used to feed a piece of celluloid into an editor. [Digital] is not expensive and that is an advantage, but I must say that I don't love it.

Technology has a great deal to do with it. The Panaflex camera was a big breakthrough when it came along; it changed everything, because now you could shoot from the perspective of a person riding in the backseat of a car.

You always like to be the collaborator. I don't want to take over the movie, because if I want to do that, I should really become a director because then you have the control of everything, basically. I'm very happy to just be the visual part of it, doing the visual part of the movie.

Mexican cinematographers Gabriel Figueroa and Emilio Fernandez were students of both Sergei Eisenstein and Toland. Their exteriors and lighting were gorgeous. And the films Ingmar Bergman did with Sven Nykvist were exceptional.

As an actor, Sean [Penn] is brilliant. And he's really an excellent director, as well. We got along really well.
