I learned early that you'd better know what you're talking about. You'd better realize that certain issues are going to be so hot - no matter what reason, what logic you apply to it - you're going to be met with an opposition just because their viewpoint is different, and there's no way they're going to accept your reasoning. Furthermore, they're going to attack you because you will be portrayed as not being credible: "You're an actor. What do you know?"

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?

We've lost our moral foundation, which allows us to go this far over. So I don't blame Trump. I just think he is what he is. We're the ones who let that happen. We should be looking at ourselves.

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.

I would see my hometown, Los Angeles, change. Green space and orange groves gave way to cement, freeways flooded with traffic, and air pollution, all in the name of "progress." I felt like I was losing my home. It had a profound effect on me, and I realized just how important nature was to my spirit, my soul, my point of view.

...if our humanity - our soul as a society - is overtaken by the materiel and cosmetic, there will be no hope of peace.

Success is a tricky mistress. It's nice to have but it's a tricky thing to embrace.
