What really matters is the work. And what matters to me is doing the work. I'm not looking at the back end: "What am I going to get out of this? What's going to be the reward?" I'm just looking at the work, the pleasure of being able to do the work. And that's what the fun is: To climb up the mountain is the fun, not standing at the top. There's nowhere to go. But climbing up, that struggle, that to me is where the fun is. That to me is the thrill. But once that's over, that's kind of it. I don't look too much beyond that.

All my life I've been dogged by guilt because I feel there is this difference between the way I look and the way I feel inside.

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.

I can't watch completed films - my wife makes fun of me.

The meter is ticking [particularly in the face of climate change], so you've got to get to as much as you can as fast as you can. I grew up with 'This Land Is Our Land,' and public land doesn't belong to that administration or this one. We want our kids to grow up with real natural places, not just photos of them.

I don't think about when it's going to stop and what you do before it stops. You just keep moving.

I started as an actor in the theater playing a lot of character parts, and suddenly, I found myself in this place where it felt like I was getting locked into a kind of a stereotype, and it did bother me.
