There's no point in it unless it's a story that you really want to tell. It's a nebulous job. Unless you're doing it well, you're not doing anything. And there are a few of those. It's perfectly possible to be a passenger on a film set because if somebody else has written it, you can make nothing of that role and that's exactly what bad directors do.

I feel more comfortable in drama. Comedy's is a high-wire act. I find it stressful. It's a precision science, in a way. And when you're filming, the thing comedy depends on becomes a much more difficult commodity. The thing you depend on is spontaneity.

But this is where you get all the market research and things get in danger of becoming formulaic, and where you depend on brands and getting recognised actors. It's the thing that precludes risk very often, otherwise everyone would be avant-garde all over the place.

Less racist now but it has been. I don't think it's been completely stamped out. There's a class element to it. And who's supposed to do what. You're very unlikely to get a gay grip.

I think England has served me very well. I like living in London for the reasons I gave. I have absolutely no intentions of cutting those ties. There is absolutely no reason to do so. Certainly not, so that I can have a swimming pool and a palm tree.

If you're playing someone who's got marital problems, you have to play someone who's trying not to have marital problems. So, you've got to get into the problem first.

If I'd loved my chemistry teacher and my maths teacher, goodness knows what direction my life might have gone in. I remember there was a primary school teacher who really woke me up to the joys of school for about one year when I was ten. He made me interested in things I would otherwise not have been interested in - because he was a brilliant teacher. He was instrumental in making me think learning was quite exciting.
