I've traveled everywhere, and it's been amazing. I used to think taking a flight was kind of a big deal, you know? I'm from the valleys of South Wales and when my family used to go on holiday, it was a big thing. Packing the bags, checking in, not losing your passport, going through customs, the X-ray machine, all that stuff used to be quite an intense thing. Now it's like catching a bus, I don't even think about it.

For one movie, I'm learning to play a violin, and I had never picked up a violin in my life. That's a big challenge. That's what I see as one of the advantages of this business. You get to do things you'd never do, in a normal lifestyle.

There's always a connection to be made whether you're playing a psychopath or whatever. It doesn't really matter; you've got to find this thing that you relate to with each character otherwise you're missing something.

I'm an only child. My mum and dad are six in each family. They're both twins, and they only wanted one. I always say to them though that they're lucky - it could have all gone wrong.

It must be weird having one child.

When I was younger, I never had that fascination.

I think my dream would have been to be a solo artist. But it didn't work out like that, and I also love to sing lots of musical stuff; I was really good at that, I've got a big voice. I dropped into musical theater and really enjoyed it and I sang for about nine years of my career.
