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

Lis Sladen was very important to me, you know. When I joined the little world of 'Doctor Who', Lis was already a star.

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

Well, I think if more people had more applause, it would make them feel better. I often give my wife a round of applause. If the meal is very good I give her a standing ovation.

Well, I think people don't recognise my face because I'm so much older now, but it is astonishing that people can recognise a voice. I do sometimes get recognised, and indeed a lot of people do come and see me.

I used to always be putting my hat on children being photographed and then getting home and discovering I was riddled with lice. That used to happen very, very regularly. I used to get headlice all the time.

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.
