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 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.

The only time it got really crazy was during 'Batman.' Anywhere I went in the world, people knew who I was. I was being offered these huge films that would have taken my career to a different level, and I decided to put on the brakes. I knew if I continued on that track, I probably wouldn't have gotten married.

I guess John Lennon had it right: give peace a chance.

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'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 have my own worries and concerns and frustrations, but I'm doing something I love to do. My wife and kids are in good shape. What is there not to be happy about?
