I'm not looking for anything other than an interesting role to play.

Apart from the fact that your physical ability starts to decline, I also think someone in their fifties being childlike becomes a little sad. You've got to be careful.

When you play a serious role, as far as I'm concerned, I feel I'm using exactly the same skills, whatever they are, to play the role as you do with something more obviously comic. It's slightly different muscles, but the same skill set.

We haven't made any particular decision [on Maigret], I haven't been asked if I want to carry on with it. All these things are a matter of whether you feel as though the idea is developing and whether it's still interesting to play.

The problem with Maigret is he hasn't got a limp, and he hasn't got a lisp, and he hasn't got a French accent, or a particular love of opera... or all those other things that people tend to attach to many fictional detectives. He's just an ordinary guy doing an extraordinary job, in a very interesting time.

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