I love working. I feel guilty about doing nothing; I get bored.

I'm so thrilled to have been asked to guest in the Doctor Who Christmas Special, I'm such a fan of the show. The read-through was very difficult for me; I wanted to keep stuffing my fingers into my ears and scream 'No spoilers!' Every day on set I’ve had to silence my internal fan-boy squeals!

My scripts are always heavily noted. If I can take a director to one side and say, "Do you mind if we try this?," a few days before, that's usually a better way of doing it then on the day.

I think some people see me as being some kind of lovable, bumbling buffoon, and I'm actually quite mouthy and sharp, and that doesn't compute.

I don't see the point of being an actor and doing the same thing, all the time. Where's the challenge there?

In 1994 while on weekend manoeuvres in France, I commandeered a Chieftain tank without permission of my immediate superiors. I then attempted to invade Paris. However, en route I stopped off at Disneyland, or Eurodisney as it was then called, and was subsequently apprehended on Space Mountain.

I'm sure people would argue this, but I want to be different in everything I do. I don't think I've been the same in anything I've done, and I want to keep that up.
