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.

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?

Like all actors, I was open to taking on new challenges, including those outside my comfort zone.

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

Between 18 and 19 years old [in the 1950s] I came to Paris. I studied art. And that experience really did change my life. I was living hand to mouth. I walked everywhere. I thought, this city is incredible but you really have to experience it by walking it.

It's a creative enterprise, just like art, just like painting, music. Creating something can be done in different categories, so to do it in film is just another expression, which is great. Because it translates so well because so many people see the work, if you're lucky.

I guess there are different ways to handle success. You can multiply it financially and use it to multiply your net worth. That's always been very appealing to me.
