I can’t think of anyone else I’d travel around the universe with than Amy Pond.

I think there are definite parallels between sport and art. There's a real sense of sacrifice. There's a real sense of dedication that is needed in sport that I think you can attribute to art. I think so much of it is about bravery and courage, being an actor.

Be brave. Don't be afraid to be stupid.

When I started Doctor Who Steven Moffat said, "That's it for the rest of your life." I'll be Doctor to a whole generation when they're 50.

Kids should feel afraid of 'Doctor Who.' All the adults I've talked to remember fondly being afraid when they were kids. That's part of the reason they remember it and love it. And if you're afraid in a controlled way, you sort of appreciate fear in some respect.

If I could film, we'd film every episode of 'Doctor Who' in New York. I have an affinity with the city. It has some wonderful locations and it is devastatingly vast and huge. Central Park looks amazing on camera.

The majority of romantic comedy movies have nothing to do with love, but everything to do with infatuation.
