I'm not that interested in someone that one-dimensional, but I'm interested in playing somebody that's more complicated.

Storytelling was a way to see the world bigger than the one you were looking at, and that had great appeal for me. I think since that was part of my upbringing, it became part of me, and I wanted to pass it along to my kids and my grandkids.

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

Generally speaking, I went through that. I came to a place where I realised what true value was. It wasn't money. Money is a means to achieving an end, but it's not the end.

The big moment for me was making 'All the President's Men'. It was not about Watergate or President Nixon. I wanted to focus on something I thought not many people knew about: How do journalists get the story?

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.

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.
