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?

I have no regrets, because I've done everything I could to the best of my ability.

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.

When I became successful, I put up a caution. I didn't think it was fair to have the shadow of that kind of success thrown on my family. And I was cautious about being taken by things that could destroy you.

In fact you've got your hands tied behind your back when somebody chooses to take a low road in to you, there is nothing you can do about it, and so you just live with it and move on.

Curiously, directing my own films have made me more tolerant and patient. I've always been an extremely impatient actor. Waiting around drove me nuts. But now I'm much more sympathetic to a director's struggle.

I think independent filmmakers, documentary filmmakers - they are journalists.
