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.

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

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.

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.

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.

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.
