“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.”

“A smart person is not one that knows the answers, but one who knows where to find them...”

“Corporate Hollywood thinks I'm a geek to go back and do theater. They don't understand why I don't want to be a movie star, why I'm not pursuing Mel Gibson's roles.”

“The beard is here because I got tired of shaving and Grissom, subsequently, got tired of shaving. Grissom, like any other 50-year-old man, is going through a series of mid-life changes. Who knows, he may start drinking.”

“We knew all along we were making a good show, so its success was not a surprise to me. What has surprised me is the magnitude of this show's success. More people see me now in one episode than saw me in 20 years of movies and theater!”

“I won't miss Grissom. It was a complete life for me that's reached its end, and it's reached it in the right way, I think. So I won't miss Grissom. And I hope that the audience won't miss him either.”

“I didn't want to play a lawyer. I didn't want to play a doctor. I didn't want to play a single dad. I wanted to do something I felt I could learn from, something that would be a challenge and something that would not dry up.”

“If I stayed a football player, my career would have been over 20 years ago. As it is, my knees are shot. I found I got the same good feeling in acting that I had in sports, but I found I could have a more profound impact on people.”

“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.”

“Theater in Chicago will always be my first love. It started careers for me and about 50 of my friends. We all love coming back. As soon as the TV show is over, I'll be back in Chicago, doing live theater.”

“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.”

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

“When we get involved in the ratings, then we're doing the network's job. We need to focus on our work.”

“I think you can find yourself on one of these shows for a long period of time and think that all you'll ever be able to do is that character. Certainly people think of you that way.”

“I've never been in this business for the recognition or the awards. I just want to do good work, grab a decent paycheck, and move onto the next job.”

“Grissom is pretty asexual. He's not that interested in anything other than work - except for Lady Heather. She's the closest to getting his heart of anyone.”

“Basically, we are a whole world of people desperately trying to figure out what is the dark side of our natures and how much can we explore without becoming something else.”

“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.”

“Grissom is a character who doesn't really want people poking around in his life. He likes to poke around in his work.”
