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.

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.

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.

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.

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.

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