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.

Some movies are what I would call murky. Just because it's murky doesn't make it artistic. It makes it hard to see.

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 should mention Vittorio Storaro, who was Bernardo Bertolucci's cinematographer. You watch those films and they are exceptional.

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.

Sometimes the shots serve as homages to other movies and other directors, like Hitchcock.

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