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.

When I speak to people from Britain, that's when I feel like a fake, speaking with an American accent.

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

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.

At home I can become lazy and if a Welsh word is really long, I just replace it with English.

I got a lot out of 'Brothers Sisters' and learnt some incredible things and I think it certainly had come to a natural ending, so it was definitely time to move on.

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.
