Lost in Space brings back a lot of memories for people, and I think that any time you're involved in something that has such a long-lasting appeal, you feel very blessed by that.

I am kind of a private person, so I don't miss that part of show business at all. Looking back on my career in television and making a movie like 'The Sound of Music' from an adult point of view, it actually seems kind of unreal. I was involved in shows that people grew up with - that hold memories for them - and it's a cool feeling.

I think here in America the space programme was such an enticing thing to be going on, that the thought of a family being able to go into space and live up there was really kind of mind-bending at the time.

People think it must be wonderful being in movies or on television, but it can be very tough on a child. I had two friends in elementary school. That was it. There was a clique of girls that were brutal to me. They pulled some very mean stuff. My two friends got me through it. Without them, I would have been all alone.

If I don't travel, if I stay at home for a week, I would go out of my mind. That is just the way I am. I love to be on the move, and I am fortunate that I have friends all over the world.

I wish more people felt that photography was an adventure the same as life itself and felt that their individual feelings were worth expressing. To me, that makes photography more exciting.

I've taken a lot of risks through the years, but I always followed my instincts and always explored new opportunities. The biggest reward has been having an idea and being able to make it a reality. My passions always lead the way - travel and adventure, fitness, art, and home.

When I was deputy chairman I could travel from Glasgow to Edinburgh without leaving Tory land. In a two-week period I covered every constituency in which we had an MP. There were 14. Now we have only one. We appear to have given up.
