William Shatner has one style. We have completely contrasting personalities. We're very good friends. I adore him, but we're very different people, so they were smart enough to write characters that reflected that.

I've been in politics all my life. In 1945, I committed my first act of civil disobedience during the election campaign for the first post-World War II general election, when the Labour Party, to everyone's amazement, ousted the Conservatives. I refused to obey the instructions of a policeman, and as a result, almost got a belt around the ear, because those were the days when policemen could hit children and nobody cared, they thought it was probably good for them.

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.

We've heard from many teachers that they used episodes of Star Trek and concepts of Star Trek in their science classrooms in order to engage the students.

I like things that are funny - in everyday conversation, in incidents that you see, in watching TV or watching film. Comedy has always had an impact on my life.

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.

Whenever the lion fish in the fish tank in the captain's ready room died it was always a sad moment.
