I always find cardio the most monotonous. Running on a treadmill shows me why hamsters are so crazy.

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.

I started doing [acting] for a living, no one really warned me about the amount of traveling I would do. I always thought everything was shot in Los Angeles.

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.

With everything you do as an actor, you obviously know the full story. But the person watching it doesn't, necessarily. So, you just have to discipline yourself to wipe the slate clean as you go along.

It's quite clear if you look at the actors in film right now, some of them came from theater but they didn't come from musical theater. There's still a bit of a stigma attached to it I would say.

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.
