Not only don't I know who I am, but I'm very suspicious of people who do know who they are. I am sometimes ten or twelve people a day, and sometimes four or five people an hour!

The success of a close friend is often wounding, especially if he has been poor for so long.

Most drama in our lives is really rather squalid.

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.

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

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

Being Doctor Who, I used to look at the clock and know at half past four we were going to stop rehearsing - and that was a sad moment for me because I wanted to stay in this beautiful, unreal world.
