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.

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

I always have been optimistic about humanity's future. Always. Even at the most dismaying of times.

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.

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.

I would like to see us get this place right first before we have the arrogance to put significantly flawed civilizations out onto other planets, even though they may be utterly uninhabited.

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.
