Nothing can ever be a rule in drama, because then you're saying certain things won't ever happen, and that would be very boring.

I like naked women! I'm a bloke! I'm supposed to like them! We're born like that. We like naked women as soon as we're pulled out of one... When Man invented fire, he didn't say "Hey, let's cook!" He said: "Great! Now we can see naked bottoms in the dark!"... The story of male achievement through the ages, feeble though it may have been, has been the story of our struggle to get a better look at your bottoms.

Amy: "Can I come?" Doctor: "Not safe in here, not yet. Five minutes. Give me five minutes and I'll be right back." Amy: "People always say that." Doctor: "Am I people?...Do I even look like people?...Trust me, I'm the Doctor.

To me, a 'brand' sounds evil.

River Song? Amy Pond? Hardly weak women. It's the exact opposite. You could accuse me of having a fetish for powerful, sexy women who like cheating people. That would be fair.

The way you get your script to the right people is that you put it in an envelope. It's easy. The difficult bit is writing something that is so good people will take a punt on a brand new writer.

An awful lot of storytelling isn't really about making people understand - it's about making people care.
