I designed 'Buffy' to be an icon, to be an emotional experience, to be loved in a way that other shows can't be loved. Because it's about adolescence, which is the most important thing people go through in their development, becoming an adult.

My dad would go to work every day and write in a room full of funny people. He enjoyed it. I know great writers who find the process agonising but to me, writing has always been sheer joy.

I loved the idea of a girl going into a dark alley, and a monster comes, and then she just aces him. It’s like, you want to see the tiny person suddenly take control. God, my whole career is basically about that!

Limitations are something that I latch onto - like working in genre, or if you're writing TV, there are act breaks, there's a length of time it's supposed to be. The restrictions of budget and sets can be really useful. When you can have everything, it's very hard to make things feel real and lived in.

The news isn't there to tell you what happened. It's there to tell you what it wants you to hear or what it thinks you want to hear.
