I think it helps to get a film made because people who put money in are nervous. They like to have something recognisable enough to make them secure that there's a pattern there - that someone else put their money into something like this and made it back.

It didn't have to be a newfound respect for the craft, I knew that it's notoriously difficult and frightens a lot of people off. I don't think anyone knows quite who to attribute it to, but the dying actor who says: "dying is easy, comedy is hard." I hear it.

So, I think there's a danger that good stuff can fall by the wayside if it doesn't conform to formula. But I think it comes down to money and they just don't know where it's going if they haven't got any precedent.

Directors don't get to see other directors at work - they're the only one on the set. I've met directors who've asked me what another filmmaker is like. So, there's probably nobody better placed to make all the comparisons and to pick up stuff than an actor.

So, you don't have laughs as a reference point any more, it becomes a bit of a science after that. And the last thing, you would love to be able to depend on a sense of spontaneity, but hours of waiting and then hours of repetition are not conducive to spontaneity so those are your obstacles. On the other hand it's a lot of fun. Plunging into a bit of physical comedy and abandoning all dignity, no one can really hurt you much after you much after that, once you've done it.

I do notice that when I've been away and I come back to London. People look at you. People are ready to pick arguments.

I always thought the biggest failing of Americans was their lack of irony. They are very serious there! Naturally, there are exceptions... the Jewish, Italian, and Irish humor of the East Coast.
