I've been able to carve out spaces for myself. At Sundance, I'm in the mountains - my property is private. I get on a horse and ride for three, four hours. Sometimes five. I get lost. But when I'm in, I'm in.

There's a lot of hyperventilation that takes off before the [Sundance Film] Festival, a lot of buzz. Every year we hear, this is going to be the new this, this is going to be the new that, and it never is. The buzz just doesn't mean anything. I'm glad it doesn't. Because I think the festival shows that what succeeds is content.

I am passionate. I am political about my country, about what it is, how strong it is, how strong it remains.

I have a very low regard for cynics. I think it's the beginning of dying.

I try to avoid giving advice. The only advice I will give is to pay attention. I don't mean to the screen in your hand. I'm talking about the natural world. I spent a lot of time educating my children about nature by putting them in nature. I said, "I want you to listen; I want you to look." There's so much technology coming into our lives that takes us away from the natural stuff, so I'm pushing the other way.

If we want energy security, then we have to reduce our appetite for fossil fuels. There's no other way. Other issues may crowd the headlines, but this is our fundamental challenge. Big challenges require bold action and leadership. To get the United States off fossil fuels in this uneasy national climate of terrorism and conflict in the Persian Gulf, we must treat the issue with the urgence and persistance it deserves. The measure of our success will be the condition on which we leave the world for the next generation.

I didn't think about politics until I came to Europe.
