Bill Mumy: (before Lost in Space) From the age of four, I was a huge comic fan and still am. When Lost in Space came along it was like being in a huge comic so we jumped at the chance of being part of that project and it proved to be a good choice.
Bill Mumy: (when asked if he'd seen Jonathan Harris in 1996) Jonathan is indeed around. He's in great shape. He's doing tons of voice over work. He and I recently made an appearance together with Leonard Nimoy, at Disney World. I think I'm going to twist his arm, and have him guest star in an upcoming Space Cases episode. Of course, he doesn't know that yet. He's great. I love him.
Bill Mumy: I'd been working quite prolifically, for about five or six years before we started Lost in Space. One week I'd be a scary mutant in The Twilight Zone and another I'd be a nice little kid in a Disney movie.
Bill Mumy: I'm very lucky to work in so many different arenas of the entertainment industry and I do enjoy them all, but making music - original music - in the studio or live onstage is definitely my favorite thing to do.
Bill Mumy: In the entertainment business, your life can change in five minutes for five years.
Bill Mumy: When you look at Lost in Space, you almost have to look at it as three different series. The first 30 episodes were done in black and white and they're kind of an ensemble adventure, early sci-fi space family versus the unknown project. Then you get to the second batch, the middle batch, which is just high pop art, bright-colored campy fantasy and comedy. And the last batch is kind of a melding of the two, but getting more or less back into the adventure, kind of superhero-y mode, although it never lost its comedic sense once it found it.
Bill Mumy: Memorizing dialogue has always come easy and quickly to me. My wife Eileen is also very helpful. She gives me choices, and asks me questions, and runs my lines with me.
Bill Mumy: My plans for the future are to pick my kids up from school and have fun with my family. I hope work continues to come to me in many different arenas.
Bill Mumy: Personally, I don't think the film and television industries are run as well as they used to be. Oh sure, we've got great digital effects now but... where are the visionaries?
Bill Mumy: Waking up at 4.30 am to have foam rubber applied to you head every day is not the same as rolling out of bed and becoming Will Robinson!
Bill Mumy: Well, I've been a big fan of comic books since I was a little kid. In fact, I used to write and draw my own comic books when I was on the old Lost in Space series.
