I retire every time I'm done with a movie. Then I go back. You know, I enjoy sleep. But I love to work; it's fun for me. As long as it continues to be fun, and I'm tolerated by the people around me, I will do it.

I'm not a poster boy for Conservation International. I'm a working member of the board.

I was never that much a focus of interest in my career. I'm aware of that now, which doesn't give me a lot of pleasure.

It's a privilege to be able to be involved with people as talented as the people I've had the luck to work with, and it's just been a great experience for me, and I'm glad that so many of the films I've had the luck to do were films that could be enjoyed by families together.

Am I grumpy? I might be. But I think maybe sometimes it's misinterpreted.

What is news? It's hard to quantify. Certainly news has changed completely, and the morning shows are not really designed to bring you the news, except to tell you what happened overnight, and the rest of it is a kind of magazine mentality - a little bit of this, a little bit of that. It's harder to be an educated and informed citizen.

The original 'Star Wars' that I was a part of really was the beginning of my working life.

I was always very grateful I was never hot. In the entire length of my career, I haven't been the most adored.

I actually like snakes! When I was young, I was a boy scout nature camp counselor, and one of our projects was collecting snakes and creating an environment for them, so I'm quite familiar with snakes and think they're fantastic creatures.

Bikes and planes aren't about going fast or having fun; they're toys, but serious ones.

I wanted to live the life, a different life. I didn't want to go to the same place every day and see the same people and do the same job. I wanted interesting challenges.

Nature doesn't need people - people need nature; nature would survive the extinction of the human being and go on just fine, but human culture, human beings, cannot survive without nature.

We're all interconnected. For example, a simple lack of fresh water can lead to population dislocation, which can lead to political radicalization, which can lead to great pressure on the states that receive refugees because of a migrating population.

I don't do celebrity endorsements. My work with Conservation International is a good use of whatever celebrity I might have to draw attention to important problems. I have the same responsibility as everyone to reduce consumption and to teach children to respect the environment.

I'm like old shoes. I've never been hip. I think the reason I'm still here is that I was never enough in fashion that I had to be replaced by something new.

Everything I do, I'm sort of half in, half out.

If you're asking me to acknowledge that I've gotten older, I can do that.

You know you're getting old when all the names in your black book have M. D. after them.

If youre going to define me properly you must think in terms of my failures as well as my successes.

You may get real tired watching me, but I'm not going to quit.

I wanted to be a forest ranger or a coal man. At a very early age, I knew I didn't want to do what my dad did, which was work in an office.

I enjoyed carpentry, and it was very good to me for 12 years.

It took me a long time to figure out how to act, and how to conduct myself in the business so I could get what I felt I needed to support my potential and give them what they wanted.

I went down to Venezuela and ended up renting a helicopter and flew with my sons to the tops of the tepuis, these freestanding jungle mesas, 'lost worlds' as it were. In fact, it's almost impossible to access them without one. So we were able to land and spend some time there. We were trapped for about six hours by clouds that came in.

The kindest word to describe my performance in school was Sloth.

I want to go back to the Pantanal in Brazil. I've never been to sub-Saharan Africa. I'd like to take my Caravan over there and do a flying safari. I've never flown to Alaska.

I have the ordinary experience of being anonymous when I'm in an airplane talking to air-traffic control, and they don't know who they're talking to. I have a lot of common experiences.

It's part of the job of the actor to torture the director.

I could take Sean Connery in a fight... I could definitely take him.

There is no child left within me, none whatsoever.

The set for 'Blade Runner' was maybe the hardest set I've ever worked on because I think we worked 50 nights in a row, and it was always raining.

I'd love to do another 'Indiana Jones.' A character that has a history and a potential, kind of a rollicking good movie ride for the audience, Steven Spielberg as a director - what's not to like?

All my friends were going off to be professionals, and I said I wanted to be an actor.

I think of myself as an assistant storyteller.

The only thing that I have done that is not mitigated by luck, diminished by good fortune, is that I persisted, and other people gave up.

My older kids are fantastic people. It can't be the result of my influence on them.

I think 'Indiana Jones' was a lot of fun to do because of the places we went to and the adventures and the action. But Han Solo was also a huge part of my life.

I accrued anger from people's low opinion of me and my work, and for the work I might be capable of.

I don't do nostalgia. It just doesn't occur to me. I'm living in the moment, and I don't have that gene.

I don't want to be a movie star. I want to be in movies that are stars.

What I observed about my fellow actors was that most gave up very easily.

To me, success is choice and opportunity.

On the first 'Indiana Jones' movie, I tore an ACL in one of my knees - can't remember which knee. The scene in which I was fighting the big German mechanic on an airplane called a flying wing, I was run over by the landing gear and injured my knee, but I can't remember which one it was. Lots of bumps and injuries along the way.

The trick of this thing and the beauty of this thing is that it's a cowboy movie first and then stuff happens. Even after stuff happens it doesn't change - it hasn't suddenly changed into another kind of movie. It's still a cowboy movie. And that's what's incredible about it because nobody has done that before, that's new territory.

I fly myself everywhere. I like all kinds of flying, including practical flying for search and rescue. And I also like to fly into the backcountry, usually the Frank Church Wilderness in Idaho. I go with a group of friends, and we set up camp for about five days and explore little dirt strips and canyons.

I'm addicted to Altoids. I call them 'acting pills.'

Starring in a science-fiction film doesn't mean you have to act science fiction.

The actor's popularity is evanescent; applauded today, forgotten tomorrow.

Nothing shocks me. Im a scientist.
