Fame is not the worst thing. I went to dinner the other night, and the girls in the restaurant ignored me. It was so annoying.

Since I was very young I've been fascinated with nature and I actually wanted to be a marine biologist when I was very young. That was a great passion of mine. So I suppose in the off season when I'm not making movies, I became more and more active as an environmentalist trying to be more vocal about issues that I felt were important.

I think the environmental movement is the biggest people's movement in the world. Unfortunately, our governments and corporations haven't responded accordingly to protect our planet's natural resources.

I like to prepare as much as possible beforehand, but there's definitely that element of fear when you're on set, and you have to be conscious of it and use that fear to drive you to work harder.

Some people don't get it when I'm being sarcastic.

I remember when I first started having these interpretations of these images, these clichés of what movie stars are and this and that, and they're egomaniacal pricks and tyrants, but in general, for the most part, they're nice people to tell you the truth.

I've changed. You can't help it. Your mind starts working in a different way. You feel really scrutinised by people.
