Encouraging people to believe in it was the most important thing of all. It's one of the reasons I was always uncomfortable whenever film crews came on the set to shoot things. I didn't want our make-believe to be exposed.

I came to feel very, very sentimental about those sets, which is ludicrous, because they represent everything which is transitory and insubstantial. It's absurd that one should feel sentimental about timber and canvas.

As the captain, I was going to be having the dominant role in most of the episodes, and that was appealing. I wasn't interested in coming to Hollywood to sit around.

I am told that there have been over the years a number of experiments taking place in places like Massachusetts Institute of Technology that have been entirely based on concepts raised by Star Trek.

During my time we had two chairman of the joint chiefs of staff, at different times of course, on the bridge, both of whom asked my permission to sit on the captain's chair.

Where can I go that would give me the same level of satisfaction as an actor?

The people who could do most to improve the situation of so many women and children are in fact, men.
