I've been telling anybody who would listen that I wanted to do a series for the last 10 years. But I wouldn't do it if I was just another cop pushing bad guys up against the wall.

I do the work just because I enjoy it on the day, working with the guys. For me, it's like going to play a game of baseball: you've got your teammates, you get to do something that's fun, hopefully, and whatever happens with that stuff is in the cosmos someplace.

I want to live and work in Chicago for the rest of my life. You know when you were growing up and you wanted to become president? What I want now is to be mayor of this damned town in ten years.

I was horrible at science and math. I couldn't pass a test to save my life! I'm surprised that it didn't take me until I was 20 to graduate. That's why my role is so cool - Grissom is the complete opposite of me.

One of the things I love about theater, one of the reasons I'll never give it up, is that it's fifty percent the audience's responsibility.

I had panic attacks during rehearsal. There were times when I really thought I wasn't going to be able to do it.

Sure, I always chose rebels to identify with - I still do - but to me a rebel isn't so much someone who breaks the law as someone who goes against the odds.
