A hero is somebody who voluntarily walks into the unknown.

I don't cause riots, but I do cause confusion. People freeze when they spot me.

'Larry Crowne' is about as bummed out a human being as one can be when he loses his job. What he is able to enjoy is something that may not be available to everybody. But it's about the value of being willing to get and willing to give good advice.

It's always a combination of physics and poetry that I find inspiring. It's hard to wrap your head around things like the Hubble scope.

If there are nine guys auditioning and they're all gorgeous, I have an advantage, because gorgeous guys are a dime a dozen. But if they need someone else - like a goofy guy with bad hair who is just okay - then that's me. And finally, the other 2 percent who audition are geniuses that I could never touch.

At the end of the day it's got to be a good movie, it's got to be a funny movie, and it's got to make people think, 'Hey, I couldn't have spent my time any better.'

Growing up in northern California has had a big influence on my love and respect for the outdoors. When I lived in Oakland, we would think nothing of driving to Half Moon Bay and Santa Cruz one day and then driving to the foothills of the Sierras the next day.

I went to college because I didn't have anywhere else to go and it was a fabulous hang. And while I was there I was exposed to this world that I didn't know was possible.

The most accurate representation of how I feel is that I'm incredibly lucky to be working in this structure where people get paid millions to read the news on TV. And, yes, it is insane. And there is nothing I can say beyond acknowledging my immense good fortune, and being aware that I'm blessed, and aware that it isn't going to last forever.

Tweeting is like sending out cool telegrams to your friends once a week.

But I also think all of the great stories in literature deal with loneliness. Sometimes it's by way of heartbreak, sometimes it's by way of injustice, sometimes it's by way of fate. There's an infinite number of ways to examine it.

Actors with political views are a dime a dozen.

There is something basic about protecting land by taking it off the market. People should be able to enjoy where they live while at the same time protect the plants and animals around them.

Now, learning how to make a movie is something you can figure out in about an afternoon. The physics of it, the marks, the lights, etc. What's hard to do is to suspend your own feelings of self consciousness. The natural actors can do that; they can become part of a characterization and learn how to maintain it.

When I work, a lot of times I have to lose weight, and I do that, but in my regular life I was not eating right, and I was not getting enough exercise. But by the nature of my diet and that lifestyle - boom! The end result was high blood sugars that reach the levels where it becomes Type 2 diabetes. I share that with a gajillion other people.

If I was to direct Ron Howard, I guarantee you, I would put him through a living hell every day. I would demand so much of him. We wouldn't quit until he leaves the set crying. Weeping! Spent!

What we're doing with Band of Brothers is trying to put it into human terms, so it is not just a flickering, black and white myth on a screen, it is a resonant story. I want the audience to recognize themselves in these men. They're not just mythic heroes.

My doctor said, 'If you can weigh what you weighed in high school, you'll essentially be healthy and not have Type 2 diabetes.' Well, I'm gonna have Type 2 diabetes, because there is no way I can weigh as much as I did in high school.

But look, I was born in 1956, the peak year for births in US history. I think I'm very representative of many of the thought processes my generation have been through and, by and large, people of my age have had their imprint planted on the consciousness of western society for a long time.

I have gone through so many examinations of what a hero is, between the World War II stuff and the astronaut stuff.

I understand the concept of optimism. But I think with me what you get is a lack of cynicism.

I want to have a good time myself. I don't want to dread going to work no matter what the gig is. I think, selfishly, I will make sure that I have a good time; how about that?

Even if a story has nothing to do with my life, if I can recognise something of myself in the character and think, 'Oh yeah, that's what I'd do...' Yeah, that's what I look for.

By and large, the making of motion pictures is all about, 'Let's ratchet it up.' And I always think, 'We don't need to ratchet this up.' If you do, don't call it 'Captain Phillips' or 'The Maersk Alabama.' Call it something else, and then you have carte blanche to do anything, down to sea serpents and aliens.

And then it was like, wait, you can go to college and study theater? And act in plays? This is almost a racket, you know. And then when the opportunity came along to do it professionally, I thought I'd won the lottery.

That's what's nice about directing a film and having it done: There's nothing more I can do about it. It's done. That's it. All I can do is let it go and hope that people are kind to it.

I think 80 percent of the population are really great, caring people who will help you and tell you the truth. That's just the way it is. And I think 20 percent of the population are crooks and liars. It's just a fact.

The nature of the movies is different than it was five years ago, and they're all driven by the possibilities of CGI, which means you can make anything happen on screen that you can possibly desire.

The year I was born, 1956, was the peak year for babies being born, and there are more people essentially our age than anybody else. We could crush these new generations if we decided too.

I must say that I do wrestle with the amount of money I make, but at the end of the day what am I gonna say? I took less money so Rupert Murdoch could have more?

No journalist has ever been in my house and no photographs have ever been taken of where I live. I don't parade my family out for display, which is the way it will stay.
