I don't think Alfonso was a big expert on Potter either. He was feeling his way through it more than I was.

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?

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 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.

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.

Well I am afraid that I am going to die, because I have just put a down payment on a house.
