I'm the only man in London that 'Don't talk to strange men' doesn't apply to.

I was never really happy until I became 'Doctor Who'.

I am a one success man.

I think people can believe in anything.

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.

Keepers of light carry invisible candles of hope, touching hearts and illuminating the souls of friends.

I'm obsessive about the kind of melodrama of getting through the days and trying to make them good and funny and a happy experience. But my feeling towards the fans is that they delivered me from darkness.
