In 900 years of time and space, I've never met anyone who wasn't important

I think that, if the world was a bit more like Comic-Con, we'd all be a little happier.

I constantly watch 'The Simpsons' and an English cartoon called 'The Raccoons' and 'Gummi Bears.' I was obsessed with ninja films, and the 'Teenage Mutant Nina Turtles,' I used to love that as well.

Actors, movie stars, rock stars, I can meet them with no worries - but with footballers I go weak at the knees. All of them.

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.

Nothing can prepare you for the changes that take place in your life - for the changes, not only in my life, but my family's. Nothing can prepare you for the enormity and the transition that you go through.
