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.

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.

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.

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?

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 want that. I want that awful intense and serious unhappiness, cos then I might feel better, and then I might be happy.

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.
