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.

In 1973, I was shown a graphic of how dependent the United States was on nonrenewable resources like oil and coal and that little was being done to change that. It seemed irrefutable that we needed a change in direction or we'd be paying a huge price down the road. That's when I made a commitment to become a political activist.

You work like hell to get yourself ahead in the business. You could go anywhere before, and suddenly you can't go anywhere. It's like being a cartoon character.

All of the films that I've made are about the country I live in and grew up in... And I think if you're going to put an artist's eye to it, you're going to put a critical eye to it. I've always been interested in the gray area that exists between the black and white, or the red and blue, and that's where complexity lies.

'Butch Cassidy' was the only film I ever enjoyed making.

As an actor and as a person you come together with being in familiar territory although that has not been my whole life. That's been a part of it. I think a lot of people associate me with the west because of Sundance.

If you could ever do a project that really has magic in it, and justifiable magic, you should do it.
