Here's an easy way to see if a war movie is being truthful: If you see an explosion on a faraway hillside and the sound of the explosion and the detonation of the bomb happen at the same time - if they're putting the sound and the vision together in the same moment - they're going toward our cultural understanding of war, not the reality of war.

I think objectivity is like this strange myth that people think you're supposed to achieve, but actually, the dirty little secret is that it's not attainable any more than pure justice is attainable by the courts.

One interesting thing I found was that if you take an affluent modern society and collapse it during a crisis, like a war or a natural disaster, people begin relating in a more ancient, organic way. They're functioning in small interdependent groups and putting others first. And another irony is that even in terrible times, cooperating makes people feel good.

The negative effects of combat were nightmares, and I'd get jumpy around certain noises and stuff, but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it, and the effects go away after awhile. At least they did for me.

At 19, your brain hasn't finished wiring itself. So the first time you have a good friend die, most people don't go through that at 19. Soldiers do. They're facing life in this accelerated, compressed form, and a lot of times, they're not ready for it.

My wife, Daniela, and I live in an old house from 1810 with three fireplaces at the end of a dead-end dirt road on Cape Cod, so I turn the trees into firewood for us and a friend of mine sells the rest.

I hope I get married one day.
