One of the things I want to do that's outside the realm of acting and the arts - although both have their place in this - is ending childhood hunger here in America.

If some crazy idea stays in my head for long enough, then there's no fighting it. I just say, Okay, let's go.

Play doesn't have to be a frivolous thing. You may think of a Beethoven symphony as something serious, but it's still being played. I think Oscar Wilde said that life is too important to be taken seriously.

I find I'm most challenged by things I really care about, because I really want to do them well. It causes quite a bit of anxiety. But that very thing you're afraid of is kind of like a blessing in disguise. If you didn't have that fear, you wouldn't have the other side - courage and bravery, positive emotions.As an actor, you get used to those fears, and you're almost happy when they show up. It makes you learn your lines and prepare.

We would do improvisation together. And that in a way, had almost a "student-film side" where we'd be sitting there with Robert Downey and Jon Favreau and we're playing around, we're jamming around and we read those pages and in next couple of days that's what we do, so it was a good experience. Kind of frightening at first because you didn't quite know how it was going to work out, but they had some very talented people there so it worked out well.

I don't know how it is for women or for other guys, but when I was young and in my 20s, I had a fear of marriage.

I'm one of those guys who will drink to, uh, kind of celebrate. I don't drink too much when I'm down or anything like that. But you've really got to be, I guess the word that came to mind is "creative," about the way you're celebrating. You want to keep the celebration going. I've learned that lesson over and over. Here on the road there's a lot of cause for celebration, but you just gotta get the damper out a little bit, and you want to keep that governor on. You want to keep your give-a-shitter in kick.
