When I visited coffee farms in Ethiopia, the farmers could not believe we spend a week's wages in their country on a cup of coffee in ours, because they see so little of the profits. Oxfam's fair trade campaign helps right this wrong.

I do think I'm a character actor.

But it's interesting being directed by someone who is a very good actor. There's nothing like it. It might sound like a territorial thing about what I do, but I don't think you can understand what it is until you've done it. I know that to be a fact.

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.

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 have almost no memory of them [St. Trinian's films]. I don't think I've seen them since I was quite young. I was a bit frightened of the girls. I fancied them. Even though I was young, I found them attractive and rather frightening. I've always been attracted to frightening girls! I'm married to one!

I've actually heard people protesting furiously about straight male costume people as well. It's not universal and there are examples that break the mould all over the place. In my experience, it's more prevalent in the UK than in America.
