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 love what I do for a living, it's the greatest job in the world, but you have to survive an awful lot of attention that you don't truly deserve and you have to live up to your professional responsibilities and I'm always trying to balance that with what is really important.

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.

I've talked to a number of actors who have gained weight for roles, and just the sheer physical toll it puts on one's knees and shoulders - no one wants to do it again. I'm 57 and I don't think I'm going to take on any job or go on vacation again and see to it that I can gain 30 pounds.

Because we are in a war situation, this can sometimes be dangerous work. But guys like A.D. Flowers and his technicians just take it in stride and get on with the job. In four years, we've never had a serious accident or injury working with all the explosions.

War is, in fact, an extension of politics, and in any war, military operations have to be conducted in such a way that they contribute to sustainable political outcomes consistent with vital interests that are at stake in that war.

I'm not so sure that people consider homelessness to be as important as, say, the Vietnam War. One should never even try to equate them because, of course, they're tragedies on both sides of the coin.

We must think differently, look at things in a different way. Peace requires a world of new concepts, new definitions.
