The element of time-travel is handled far more intelligent in Harry Potter.

I like time off. I'm not a workaholic.

'Naked' kind of kicked me off into the film world. It just so happens that all of the things that I have been offered have been films, and I've enjoyed the travel that goes along with that.

I'd had a relationship with a French girl, a Japanese girl, an American girl, a Filippina and she was there all the time - a Lancashire girl. I thought: 'It's a Lancashire girl I was looking for. Why didn't I realize it?'

It's certainly not easy having to spend a lot of time apart, and having a five-year-old child who's got to be at school. So we need to learn how to organize our time really well because for months we will be in two different countries.

I had such a nice time making it, and I can't wait to make the fifth one. The whole crew were just really, really lovely. All the costume people, the make-up girls, the kids - even my driver.
