I'm certainly not one of those actors who remain in a dark place the entire time in order to be doing the scene. I sort of come in and out of it. It can be to the detriment of my performance sometimes!

I first went to the Chubut valley, the colony that runs about 800km across the width of Argentina, in 2000. My uncle had been there tracing family and came back saying I had to go. So a year later I did.

I'm 33 now and I seem to have hit a fitness plane. Shifting the wobbly bits isn't as easy as it used to be.

It's weird how your perspective changes. At the start of your career, you think, 'I just want to do cutting-edge work that makes people think.' Now, I would do a blockbuster in a heartbeat.

I love the stage. I'm always sniffing around to see if there's something I can squidge in quickly.

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.

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.
