Some people burn out, and some people like Clint Eastwood, he was a wild, international movie star in his 30s, and he's doing the best work of his life now. Go figure.

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.

The drones are really interesting - how have the troops withdrawn from Afghanistan? Because we've upped the drone strikes and most of the country doesn't even really know what that means or who we're killing or... it's such a new weapon that we don't know what the long term impacts of that kind of military action is going to be.

Right now, if you're interested in being a dramatic actor, they're not making that many just regular dramas. Movies have to have some other thing going on.

The constant buzz and pressure and noise and static of the Internet, and the way it makes young people feel makes it difficult to grow up and develop the way one might want to.

I enjoyed meeting Emma [Watson]. I have a soft spot in my heart for child actors growing up. I know how hard that is. Having gone through that experience myself, I have a lot of sensitivity to it. For lack of a better word, I just feel like I love these kids, and I want them all to grow up and love themselves, and not get caught up in the wrong things, and to learn all the different things this profession has to give, and to understand it.

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.
