I am one of those actors who does feel a change when a wig and fake nose are put on. Even the weird little things, like glasses - it's almost like having a mask on.

Me and my friend Ioan Gruffudd are like chalk and cheese when it comes to clothes. He lives for his clothes and has an amazing wardrobe. If we're going out I'll turn up at his house and say, 'I haven't got anything to wear,' and he'll tut and sigh and then lend me something swanky.

Within the microcosm of a film you get drawn to people. There are certain projects you care enormously about, and 'The Edge Of Love' was one because I was portraying a great hero of mine, Dylan Thomas.

I think my mother would be very happy if I found a nice Welsh girl.

In my twenties, I thought I was Robert De Niro and I invested all of myself in my acting. But, as I've got older, I've calmed down a bit. I've thrown my game plan out of the window.

As for waxing, I've never waxed in my life and I never would. I'm extremely Welsh, so I draw the line at removing body hair.

I definitely want to go back to the theatre. It is hard work, it is repetitive, but it is intensely rewarding.
