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.

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.

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.

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.

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.

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 know a lot of actors who've just gotten bitter because they did something and then nobody ever saw it or whatever.
