People think because I can make them laugh on the stage, I'll be able to make them laugh in person. That isn't the case at all. I am essentially a rather quiet, dull person who just happens to be a performer.

I have always worried about things more than I should.

I think you're bound to get a sense of any character that you play. It's not something you often do in comedy.

ITV and the production company contacted me and asked if I fancied playing the role [of Maigret]. It took me a long time to decide to do it. In fact, I decided not to. I thought about it for some weeks, and thought 'perhaps not' and it went away for a while, and then it sort of came back. They said 'Are you sure you don't want to play him?', so I thought about it for a lot longer again, and eventually decided that I would.

I enjoy racing historic motorcars from the '50s and '60s. The seed of my interest was planted when I was about 12 years old and took over my mother's Morris Minor. I drove it around my father's farm. But my favorite car is still a McLaren F1, which I have had for 10 years.

I would never wish to say that I've finally waved goodbye to any character, it's just that the emphasis tends to shift.

I don't really have plans like that [move towards more dramatic acting].
