Rose Tyler: Can't you come through properly? The Doctor: Then the whole thing would fracture. The two universes would collapse. Rose Tyler: So?

Steven wrote to me today, saying, 'Don't you feel like sticking your head out of the window and yelling, "I DON'T KNOW WHAT I'M DOING!!!"' Yes, absolutely. Solidarity. Fear is always the same. Different worries with different scripts, but the same baseline fear.

Writing isn't just a job that stops at six thirty... It's a mad, sexy, sad, scary, ruthless, joyful, and utterly, utterly personal thing. There's not the writer and then me; there's just me. All of my life connects to the writing. All of it.

Cyber Leader: Daleks, be warned. You have declared war upon the Cybermen. Dalek Sec: This is not war - this is pest control! Cyber Leader: We have five million Cybermen. How many are you? Dalek Sec: Four. Cyber Leader: You would destroy the Cybermen with four Daleks? Dalek Sec: We would destroy the Cybermen with one Dalek! You superior in only one respect. Cyber Leader: What is that? Dalek Sec: You are better at dying.

Anything works, as long as you write it properly.

Wilf: God bless the cactuses! The Doctor: That's cactI. Alien: And that's racist!

My God, that scene in Monster Inc. where the monsters realise that their entire world is founded on hurting children -look at that for a change! Two galumphing cartoon characters making a shattering realisation about their world and their role in sustaining it. A truly epic moment. It's stunning.
