You can't be a casual observer of something humorous - you have to engage, you have to find it funny for the relationship between actor and audience to work.

When I was in my 30s, I was at the end of a long-term relationship and going through a very hard time. I'd had about 15 different addresses and a series of relationships. I thought, 'It's time to have a look at yourself.'

I was supposed to have a relationship with Judy, but that never happened. Actors in series didn't have the control that they have today over their jobs.

The only person who had any control was Jonathan Harris. His character was so flamboyant that he was able to make things happen. My character was fairly one-dimensional, so I had my relationship with Dr. Smith and with the family.

My work is about life as you and I experience it. You're either lucky or you're not lucky either your relationship works or it doesn't.
