"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."



"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 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."



"If I could change on thing about myself, I would: Have better knees. Mine are shot because of injuries. You're only as good as your legs, whether you're an athlete or an actor."



"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."



"Grissom comes from a place where we know he had a deaf mother, he was raised in a silent household, on some level, had a father who potentially was not around and he learned what he knew by himself in the back yard, with bugs and animals. He's not comfortable being a supervisor and that's his problem."



"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."
