I'm not unattractive, but I'm not a matinee idol. I think I have a very non-threatening look - I'm fine, I'm right in the middle.

Some people just derive great joy from making other people laugh. And I do, but I don't feel like I need to do it 24 hours a day.

What kind of person would have a real craving for gummy worms?

I remember my wife wanted me to go see 'Contagion,' and I was like, 'Oh my God, why would I want to see that movie?' I mean, I'll just have nightmares and it will freak me out. It turned out that I really enjoyed it; I thought it was very well done.

I think in most relationships that have problems, there's fault on both sides. And in order for it to work, there has to be some common ground that's shared. And it's not just one person making amends.

How did I end up in films with people like Keira Knightley... all these beautiful leading ladies and me - it's kind of shocking.

[And on going from character to leading actor] I don't approach anything differently; I just approach it as a character. I'm always astounded at the fact that I've ever played a leading character in anything [Laughs]. And my wife concurs with that, frankly. She always thought I would be, at best, the wacky neighbor on a sitcom, so this is all just a surprise and a joy.
