'Quantum Leap' gave me a huge opportunity as an actor. The nature of the role and it's demands allowed people to perceive me as a versatile actor, and the wide success of the show around the planet gave me a certain notoriety that helped me get other work.

After 'Quantum Leap,' a lot of sci-fi things came my way, and I had to say, 'I can't do that right now.'

I went into show business because I love to work with people, and what I enjoy most about acting is rehearsing and getting to know people and their talents, forming relationships. Working in this business, barriers drop and you get into people real quickly.

It's a joyful, humbling feeling to be in different places around the planet, and people have seen shows that I'm proud of being a part of, that do have things to say about the human condition, the planet, and who we are and where we've come from, that will sustain.

I was a huge fan of the original 'Star Trek,' and I'd never even dreamed that I would someday be captain of a starship.

The great thing about show business is that there's no mandatory retirement age.
