You take this cold, remarkable, difficult, dangerous, borderline psychopath man, and you wonder what might have happened to him had he not met his best friend, a friend that no one would have put him with, this solid, dependable, brave, big-hearted war hero.

[The Doctor, Capt. Jack and Rose are cornered by the empty children.] The Doctor: Go to your room! Go to your room! I mean it. I'm very, very angry with you. I'm very, very cross! GO! TO! YOUR! ROOM! [The children lurch away and obey him.] I'm really glad that worked. Those would have been terrible last words.

I think of myself as a writer with a sense of humour rather than a comedy writer. Happy to tell a story with lots of jokes in it - I wouldn't know how to do jokes without the story.
