My problem is that the audience is more fiction-literate than ever. In Shakespeare's day, you probably expected to see a play once or twice in your life; today you experience four or five different kinds of fiction every day. So staying ahead of the audience is impossible.

Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. Now and then, every once in a very long while, every day in a million days, when the wind stands fair and the Doctor comes to call, everybody lives.

I hope I won't become hated by geeks everywhere, but I don't really know comic books all that well.

I absolutely love television, and I don't mean to be vulgar, but as I keep having to explain to people from the movie industry, I get more power and more money doing television, so why on earth would I do a film?

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.
