Like, on the 'Parks And Rec' set, I still feel like I'm a guest star. Being a fan of the show, it's really surreal to be on the set and see that it's not real, and getting to know the actors and they're not their characters.

I wasn't offered a role in 'Expendables 1,' and I'm a guest star in 'Expendables 2.'

I like everybody at 'Criminal Minds.' I would like to guest star, but I don't know if that is in the cards.

I feel a tremendous responsibility to my crew, to my cast, to every guest star that comes on.

When you're a guest star on TV shows - particularly in the 1960s - you're always the villain.

When you're a guest star on a movie or a TV show, I always say it's like being invited to a family reunion, but it's not your family. So you don't belong - they're being nice to you, but you don't fit in completely; you don't know everybody's story. You don't have a history.
