You've got to be in the moment and respond to what you're feeling. I try to simplify it as much as possible.

In 10 years, I’d love to live near the sea, in a warmer climate. I could see myself with three dogs…and it’d be great to share them with someone else.

For your own self-respect and sanity, your creative freedom, you have to be careful that you don't rely too much on other people's opinions of what you do because it can stunt and inhibit you.

I always wanted to sing, as a child.

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.

On Broadway and in the United States it's very different - people crossover all the time into television. I think that we'll get there [in London] in the end, but it has to start with who comes to see you in the musical and whether they can see beyond the dancing and the singing.

It must be weird having one child.
