I find acting in contact lenses is bizarre to me, because there's just a giant filter between you and the world. I know it sounds painfully, ridiculously obvious, but it's true. You're just so detached.

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 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.

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.

I would absolutely love to go back to the simplicity of the '80s, where there wasn't texting, social media, iPhones, or smartphones. I love the fact that you would go home and check your messages. I'm not well suited to the world of modern technology.

I do like to keep my private life to myself. But then again, I don't really get up to much.
