I love sci-fi because it leads in the imagination, and I always say it has the most intelligent fans in the world.
When I see myself on film it makes me smile, I mean making a good living doing what I enjoy is soo much fun. I just hope that everyone has the chance to enjoy life like I do.
I've never really worked on them. Just once in a while one hits me and makes me laugh. My Al Gore was sort of like a gay Gomer Pyle.
