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."

Sometimes to think about why some institutions are stable, it's interesting to go one generation back and look at the author of that stability.

It's an unknown quantity. It's actually almost a cliché to say it, how hard comedy is. What's that famous quote? "Dying is easy, comedy's hard." I think the broader it gets, if you miss by a millimetre, you've missed completely. It's a very hard thing to do.

'La Dolce Vita' made we want to go to Rome and, if not jump into the Trevi Fountain, at least watch someone else do it. Maybe that's why I married an Italian...!

I often think it can often be very difficult for comedians to revisit the same gag. I think Russell's a bit more than a comedian.

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 don't think it's aiming at gags, I think the humour is woven into it. It's part of how the characters operate and how they deal with disaster because they're worldly enough to have a bit of irony and wryness about their own circumstances. So, I think the humour comes out of that.
