We've been given this gift, our planet, and we've found no other place in the universe that we can inhabit. I want to do something to create radical change to help save it. It's our responsibility.

We must set an example now and move environmentalism from being the philosophy of a passionate minority ... to a way of life that automatically integrates ecology into governmental policy and normal living standards.

I'm shy, but when the time comes to be wild, I'm fun-loving, adventurous, and mysterious.

I got everything I need right here with me. I got air in my lungs, a few blank sheets of paper. I mean, I love waking up in the morning not knowing what's gonna happen or, who I'm gonna meet, where I'm gonna wind up. Just the other night I was sleeping under a bridge and now here I am on the grandest ship in the world having champagne with you fine people. I figure life's a gift and I don't intend on wasting it. You don't know what hand you're gonna get dealt next. You learn to take life as it comes at you... to make each day count.

I've never tried to reach a certain demographic of an audience or try to say: OK, now I'm going to do this type of film to transition myself into more adult roles. Or a romantic hero. Or whatever it may be.

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

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.
