It still frightens me a little bit to think that so much of my life was totally devoted to Star Trek and almost nothing else.

For seven years I did very little theatre, and I have to make up some time.

The only still center of my life is Macbeth. To go back to doing this bloody, crazed, insane mass-murderer is a huge relief after trying to get my cell phone replaced.

I've met actors where you think, if only you could just clean up your act and get it together, people would want to work with you. Some people are so difficult, it's just not worth working with them.

I've been an activist all my life. And always a liberal activist, for the simple reason that it is on the liberal left that you find the true recognition for the need for fairness in society. I'm not saying equality, because that you can never achieve, because equality is based on such complex criteria. But fairness is another issue.

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.

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.
