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.

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.

They said: "Make it in this amount of time and go for it now..." Which is why I was suddenly ambushed and we all found ourselves doing it. I suspect this wasn't quite recognisable in its genre to give people the confidence just to throw money at it.

It's whether they have a vision and whether they're able to communicate it. The best director is just someone who gets over-excited about doing it - they don't even have to know much about camera or acting.

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.

I think everyone is throwing happy stuff at you, and that's when you come over all humbug. It's happy stuff in your face, happy stuff is being sold to you.

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.
