I call Sally Field 'America's Mother!' She is incredible to watch.

I've done a number of projects where people go, 'This is your breakthrough role,' so I've stopped thinking that.

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

I've realised that nobody's going to die if I don't get it right and that there are a number of things out there, beyond acting, that are very interesting and fulfilling.

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.

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 was shocked by the amount of Welsh people in L.A. We'd go to this British pub to watch the 'Six Nations' early in the morning and I remember the first time I walked in it was just a sea of red.
