The more I've acted, I've realised that I have a) no control of and b) no way of really quite understanding how people react to anything I do, or any movie I do.

When I was doing 'This Boy's Life' I wanted to be as old as Robert DeNiro and as experienced as him and have the same respect as he did in that movie.

I've managed to keep a clear head and remain sane in this business because I remain a kid off-camera.

Right now, our mother -- our mother -- all of our mothers, Mother Earth is hurting. And she needs a generation of thoughtful, caring and active kids like all of you to protect her for the future. You can help us win the battle to clean up our air, our water, our land, to protect our forests, our oceans and our wildlife.

I like girls who are intelligent, somewhat funny, and pretty with a nice personality.

At first glance, you read something on the page and it can seem one way, and you can have your decisions before you wind up on set about what that set is supposed to mean, but until you're actually there doing them, there's really no way to understand it.

There's so many intangible forces that come into play when making a film, I have no idea what the public will ultimately think of something that I do, let alone critics.
