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

If you need to strap a camera to you or get in a small space, then it makes sense to use digital.I do think it is possible to use a digital camera artistically, but it can only be good if you are using film technique. Film has grain, and digital has pixels, and there is not that much of a difference, but digital does not replace the need to create a scene and light it properly and spend time considering the shot.

I think that film is still an artform and it doesn't really matter if you're using a digital camera or a film camera.

It's all about special effects and explosions now. It leaves me just cold when I walk out of the theater. There's no heart; there's no soul. Movies used to be about people. It's as though we don't tell stories any more. The studios have to make money, and if you want to make $20 million, you have to spend $200 million.

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

I really like to work with people who know a lot, but they also give me space so I can add something to the movie.

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.
