“I think that's the way people absorb television. All the explanations in Doctor Who are there if that's your bag, but they're not essential to your enjoyment of it. An awful lot of storytelling isn't really about making people understand — it's about making people care.”

“You're guaranteed to be lucky several times in your life-it's what you do with it. Young writers spend all their time worrying, in a way that David Gerrold did not and I did not. How do they get to meet the right people? How do they get to the right parties? If only someone would read my script... Forget all that. All these things are easy and will happen. The way you get your script to the right people is that you put it in an envelope. It's fucking easy. The difficult bit is writing something that is so good people will take a punt on a brand new writer. That's it-you have to write an absolutely terrific script.”

They're blue... boring-ers! Amy: Doctor, how come she can fly the TARDIS? The Doctor: You call that flying the TARDIS? [scoffs] Ha! River Song: Okay, I've mapped the probability vectors, done a foldback on the temporal isometry, charted the ship to its destination and... [presses a button, the cloister bell clangs] parked us right alongside. The Doctor: Parked us? But we haven't landed! River Song: Of course we've landed; I just landed her. The Doctor: But it didn't make the noise. River Song: What noise? The Doctor: You know, the... [does an impression of the TARDIS materialisation sound] River Song: It's not supposed to make that noise. You leave the brakes on.The Doctor: Yes, well, it's a brilliant noise. I love that noise.”

“See the bowtie? I wear it and I don't care. That's why it's cool.”
