I keep myself content by doing lots of different stuff and make sure that my next role is completely different to the last. I just enjoy the versatility of it, the challenge of doing lots of different things. It keeps the job interesting.

I walk to Oxford Street and climb on the number 8. It's freezing and it starts to rain and it's the ugliest bus I've ever seen, rattling down the ugliest streets, in the ugliest city, in the ugliest country, in the ugliest of all possible worlds.

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 wasnt the greatest script in the world, but not many people can say theyve played a wicked king in a swashbuckling Arthurian special-effects monster movie.

The making of 'Naked' was an absolutely phenomenal, mind-bending experience. That film was life-changing and put my career onto a whole different level.

I don't worry. I'm more stoical. Of course I have insecurities. I fear getting older. I fear death and illness. I'm not prone to depression, but I get depressed because everybody gets depressed. Suddenly I'm away from my family or doing a job I'm not enjoying.

Alfonso Cuarón, in the rehearsals, without J.K. Rowling's knowledge, told me that [my character] was, in fact, gay. So I'd been playing a part like a gay man for quite a long time. Until it turned out that I indeed got married to Tonks. I changed my whole performance after that. Just saw it as a phase he went through.
