When judging others it's the intangibles that we often miss.

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.

I wasn't interested in novelty. I was looking for good drama.

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

Plenty of clever children have to pretend to be not clever or else they get bullied by the thick.

I'm really not an actor of any kind. I've always seen myself as an entertainer, someone who makes people laugh. That's all I've ever wanted to do. 'Doctor Who' has always just been me, really.

I've never ever read a script. I really must read Macbeth, because I was in it once. I got a lot of laughs in that, I can tell you.
