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.
William Petersen

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.
William Petersen

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.
William Petersen

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

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.
William Petersen

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.
William Petersen

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

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.
William Petersen

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.
William Petersen

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.
William Petersen


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.
William Petersen

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.
William Petersen

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.
William Petersen

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.
William Petersen

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.
William Petersen

Now I'm seen by more people in one episode than I was in 20 years of theatre and movies. It's gratifying to have an impact on 25 million people a night, but I can say goodbye to my lunch-pail life as a working actor. I'm scared I might be a celebrity.
William Petersen

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.
William Petersen

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.
William Petersen

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.
William Petersen

The show can go on without me, and probably will, but I want to come back to act in Chicago. My wife and I just bought a condo downtown, and I want to do theater.
