One of the reasons I'm an actor is because I was no physical specimen as a child. I wasn't athletic and didn't have any prowess in that regard. Growing up in Kentucky, most little boys were trying to get into sports, and it was very competitive, so that was not to be. But I did want to do something.

When you see a struggle that you may be having personally put on a big screen and in a roomful of people, then it makes you feel less crazy or alone, because you're seeing that other people are dealing with it too. You get to see in this imaginary scenario how people might try and answer some questions or deal with some problems.

I like to play characters that get to do it all - to have a bit of comedy here and a bit of pathos here and a bit of suspense here, that's what's fun.

If you don't believe there's some organising principle, or somebody up in the sky pulling the strings, then it can be very stressful. And nature itself is very arbitrary - it's not malevolent or benevolent; it doesn't even know we're here.

You can't escape this feeling of disintegration. The world is fragile. But you also can't let it ruin your life. I'm actually a pretty composed person. I guess people imagine I spend my life thinking about crazy, sinister things but I don't, really. It's not like I'm trying to exorcise any demons.
