In my head, I think I'd make a perfect spy, but in reality, I don't think I'd fare very well.

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.

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

I wasn't one of the cool kids by any stretch. I just bumbled along really.

Generally speaking, I'm a jeans, T-shirt and boots man but I do own an Armani suit, which gets a regular outing. It's nothing fancy - just a classic, well-cut suit with clean lines and beautiful tailoring. It's timeless and you can mix and match it with anything to dress up or dress down.

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.

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.
