The one thing I would never wish it to be thought is that you play serious roles in order to achieve some sort of respectability which you can't if you're playing comedic roles.

In TV, and in particular in commercials, you don't really need to explain very much at all - you just say he's a spy and he's a little bit theatrical and overblown and smug and he's not very good at his job.

But I always feel that whatever I do, I could do better. I suppose it is perfectionism.

I have always worried about things more than I should.

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'm not a collector. I don't like the toy cupboard syndrome that causes so many good cars to evaporate.

Although the great frustration about this [role] is the fact that there's one thing Maigret never does, and that's drive. He's always driven, or he takes the train, or he gets the bus. I was saying 'Well, why don't we ring the changes for the 21st Century, and stick him in the car?'. [Executive Producer and son of the author, John Simenon] said, 'Well, you can if you want, but there'll be lots of people who won't like it'. So he's a non-driver ... But no, Top Gear was never a consideration for me; and neither was I asked
