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'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 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.

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 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.

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.
