When I look in the mirror, I don't see my Dad, I see my grandmother. For a while it was my mother looking back at me. If only it was my Dad.

It's a funny thing - the reality is I have no feelings about school. It's long gone. Funnily enough, the bad memories - of which I don't have any left to be honest, I can just remember a sense of tedium - have faded. And teachers that I liked have remained quite vivid. There are three or four left.

I do think a good story in a novel is fair game and there's nothing wrong with adapting that. It sometimes gets a bit facile where they think: "Let's get the next best-seller and see if we can turn it into a film."

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.

To be bothered wherever you go - it's not a rational thing to want at all.

My primary instinct as an actor is not the big transformation. It's thrilling if a performer can do that well, but that's not me. Often with actors, it's a case of witnessing a big party piece but wondering afterwards, where's the substance?

If I were to write a book about the progress of getting to a third film, it would be a long one.
