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.

I quite like the transitions of being an actor, because you get to explore these little pockets of life. So if you're playing a builder you get to know about building, if you're playing a scientist or a physician or something you get to know about physics. And similarly with this world I like exploring their culture, that very sort of upper middle class, addictive... that's part of the reason I love it.

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.

Being an actor is about having the courage to follow your instincts, and also having the discipline and dedication to sacrifice the things in your life that you need to sacrifice to get the best out of yourself artistically.

If I was making a tea advert, I would want to communicate about tea is that it can console you, it can start your day, there is the warmth and the ritual, and you can share it; you make someone a cup of tea and you offer it to them.

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.

Amy Pond, there's something you'd better understand about me 'cause it's important, and one day your life may depend on it: I am definitely a mad man with a box!
