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.

Theater in Chicago will always be my first love.

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.

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.

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

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.

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.
