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.

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'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.

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

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.

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.

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.
