I've been involved in one or two successes in classical plays but nothing to touch the excitement and the glamour and the gratification of being a children's hero for so long.

The thing is I'm very interested in bad taste, as anyone who's ever seen me perform or had dinner with me would know.

Actors are able to trick themselves into treating anything as if it's fantastic. It's a kind of madness really.

You know, you're a classic example of the inverse ratio between the size of the mouth and the size of the brain.

I have never described the time I was in Doctor Who as anything except a kind of ecstatic success, but all the rest has been rather a muddle and a disappointment. Compared to Doctor Who, it has been an outrageous failure really - it's so boring.

Respect is more than giving consideration of one's feelings. It is showing common courtesy for another human being.

I have no regrets about being 'Doctor Who'. It was the greatest thing that ever happened to me.
