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.

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

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.
