There's only so often you're going to have an opportunity to contribute at a high level and that you should be grateful whenever one presents itself and not take it lightly.

Alejandro Amenábar is a very interesting filmmaker. I had really liked The Others, which was a movie he made with Nicole Kidman a few years ago. He made a very compelling case about how much he wanted me to be in this movie. Whenever a really passionate, talented filmmaker seems to have an interest in me, I take it very seriously because I like to work.

If you study the history of mankind, it seems to be a history of violence. Certainly the history of art, whether you look at paintings or movies or plays or whatever, is just a litany of murder and death.

Alejandro Amenábar has a unique way of approaching movies and thinking about something which was new to me. It was different. I have a lot of respect for him so I just took a gamble.

Depression is a real demon in the woods for a lot of creative people, you know? It's part of what the documentary is trying to be about for me, finding balance, where the beauty that is attainable in the creative arts can be matched with the scratchy roughness of regular life.

I auditioned for Robert Redford once and I was so starstruck I couldn't even speak. I had a mic wire at a screen test clipped to me and then I got kind of nervous and I paced in a circle and then took a step and tripped and fell on my face. You just have to forgive yourself and keep going on.

I think having nature be a part of people's lives helps all of us see ourselves as part of something larger.
