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 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.

Marty [Scorsese] knows that when an improvised moment comes out of a real situation, it's gonna have more life and more going on than anything you can imagine and that's how the character can become the story

From an outsider's perspective, it's amazing what [Clint Eastwood] does. If he's not directing a film, he's acting in it, or rather he's composing the music for that film. His commitment to what he does is astounding for all of us to witness. It's inspiring, actually.

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.

It's a weird feeling when people are defining you, and you haven't even defined yourself.

We are facing a tipping point of environmental crisis unprecedented in human history and our very survival is dependent on protecting nature.
