I don't know that 'NCIS: Los Angeles' is a complete reinvention, but I'm playing one of the guys in charge this time. Before I'd be cast as a young impressionable character. I think part of that is just being more mature.

I think I'm pretty smart on what I spend my money on. I still don't have a new car, I drive my old car that I've had forever. But I bought a house in downtown Chicago.

I definitely had those moments, like any actor, when you get anxious and think, 'When am I going to work again?' But I would feel that way even when I had every offer in the world coming to me. Then I became a father and I felt a little more of the anxiety that came with the responsibility of being a parent.

My wife and I have mellowed out as we've gone along. With the first baby, when she cried, we'd think, Oh my God, what do we do now? But with Finley, our fourth - he's the easiest baby ever, and I think that has a lot to do with the fact that we're much more relaxed these days.
