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'm from a big family - I'm the youngest of seven - and my wife is one of four. So we always wanted a lot of kids. It's what we're used to, and for us it's what life is all about.

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 would be in Italy working on a film, longing for something simple - like, God, I would just kill to be sitting at a barbecue having a beer right now.

I look to my family for my support. I'm fortunate to have a big family.

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.

I knew when I got into this business I couldn't have it both ways: I could live the playboy lifestyle, which is not a bad thing to do, or have a traditional family life, which is how I grew up. And that was more important to me.
