I've been watching 'Californication' since the pilot aired and had always thought that it would be so much fun to guest star on.

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

One person I've always wanted to work with who would be an amazing guest star would be James Earl Jones.

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

I would love do a guest spot on 'Castle' because Nathan Fillion is so dreamy, and he and I are friends. And I think we could have a lot of fun.

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