Telling the story with only a few shots, I love that style. It makes you feel like you're part of the action, part of the story. It reminds me of the theater, where one act is basically like one long shot. It almost makes you forget that you're seeing a movie.

A good [film] director is talented, imaginative, and does his homework.

When you are shooting a movie, you have to collaborate with many, many, many people. First of all, the director with all his own ideas and I can only just help him with that. I cannot change his idea.

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.

We used hand-held cameras 50 years ago. It wasn't something new. Sometimes we used a tripod, or we'd have a tracking shot, and sometimes - like when a character was being chased - we used a hand-held camera because it was right for the scene. In those cases, it helped the mood; it created immediacy and a feeling for the viewer that they were in the scene and in the moment.

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.
