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.

It wasn't a good idea to work on 'Naked' in the first months of a marriage. I was living apart from my wife in a flat overflowing with books I was reading for the part.

I'd been a stepparent for about two years with a woman who had a child, and I came to realize I adored children and was good with them. So I was very happy when Anna got pregnant.

When you do something well, this is the best job in the world.

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.

And it was only released in London last week, so when I go back to England Monday or whatever, I am expecting heaps of adulation. I'm hoping there is. If that doesn't happen I will be disappointed.

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.
