I haven't been approached to do a 'Doctor Who' movie. I think they would be scraping the bottom of the barrel if they asked me to do it.

'Doctor Who' is pretty dark, I think. Generally it's dark; it's always been dark.

I travelled across the world. From the ruins of New York, to the fusion mills of China, right across the radiation pits of Europe. And everywhere I went I saw people just like you, living as slaves! But if Martha Jones became a legend then that's wrong, because my name isn't important. There's someone else. The man who sent me out there, the man who told me to walk the Earth. And his name is The Doctor. He has saved your lives so many times and you never even knew he was there. He never stops. He never stays. He never asks to be thanked. But I've seen him, I know him... I love him... And I know what he can do. - Martha Jones

He's like fire and ice and rage. He's like the night, and the storm in the heart of the sun. He's ancient and forever. He burns at the center of time and he can see the turn of the universe. And... he's wonderful. - Tim Latimer

Geronimo!

You don't want to take over the universe. You wouldn't know what to do with it beyond shout at it.
