The first couple of weeks of filming were quite tricky for me to find my feet with the character [Maigret], which wasn't helped by the story that we were telling.

What directors of television drama constantly tell you is 'Don't act it. Don't try. Don't emphasise that word'. Whereas with someone like Blackadder, even though he's a relatively low key character in a way, he did relish the lines that he had and the words that he was given, with a lot of inflection.

My personal problem is that I take the business of film-making so seriously that I find it very difficult to relax.

Having spent a substantial part of my career parodying religious figures from my own Christian background, I am aghast at the notion that it could, in effect, be made illegal to imply ridicule of a religion or to lampoon religious figures.

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.

The character [Maigret] is bound to change and develop, and I wouldn't like to claim that we are perfectly formed straight out of the box. I think it's what I'd call an 'optimistic start'. As you know, for me, no glass is anything other than half empty, so I apologise for my reticence in terms of promoting this programme.
