Favorite Star Trek: DeForest Kelley
He was just a really laid back and nice person. Answered every question no matter how bad it was. Just a real class act. My only regret was that I was not as familiar with his non-Trek acting career when I met him.
Favorite Non-Star Trek: Jonathan Harris
A lot of great stories from a long career that was not limited to "Lost in Space." I could have stayed up through the night listening to him recount some of his experiences.
Least Favorite: Harlan Ellison
I do not wish him ill. He is a talented writer without question or qualification, but I just didn't care for the man.
