I think the thing about film is, as it gets proved by a lot of young filmmakers now, that the medium will just go on reinventing itself, and so you just hope to be a part of that and not a part of some kind of endless regurgitation or 'Here I am doing what you know I do' kind of thing.
You can act truthfully or you can lie. You can reveal things about yourself or you can hide. Therefore, the audience recognizes something about themselves or they don't -- You hope they don't leave the theatre thinking that was nice...now where's the cab?'
I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
I'm very aware that when one is acting in the theater, you do become kind of animal about it. And you're reliant on instincts rather than tact a lot of the time.
Film has to be reflecting the world that we live in, and that's all you want to be a part of. Actors inhabit the same planet as everyone else. It's a weird thing that happens when you're an actor because people hold you up because you somehow embody in parts groups of people or people's hopes or something.
