Generally I know that we've hit on a good idea if there's a moment where I'm going "HA HA HA!" because that's usually my starting point, me laughing.

I pitched Jay Hunt the opening scene (prime minister, middle of the night, he's woken up...). She paused, and then she laughed. She was very intrigued and all that, and then she said, "Does it have to be a pig?" So we went through various options: Could it be a supermarket frozen chicken? A giant wheel of cheese? A pig seemed just the right level of absurd, but then when he walks in and there's actually a pig there, it's awful.

Whenever anything nice happens in the world I always expect something appalling to happen immediately afterwards.

What we were also trying to do is vary the tone slightly across the season of Black Mirror, because there are six stories this time around, so you don't want it to just be the devastating, bleak-em-up.

[British television series] Hammer House of Horror. I used to really enjoy these one-off stories where often there would be an incredibly cruel twist. A good example is the episode with Burgess Meredith and there's a nuclear war and he drops his glasses. To this day, you can show that to anyone and they'll go "Bwrrrrrrrr!" You know, sort of wander away shuddering.

Women - why aren't you running the world yet? Frankly I'm disappointed in you. Men are still far too dominant for their own good, and consequently we've made a testosterone-sodden pig's ear of just about everything: politics, the economy, religion, the environment ... you name it, it's in a gigantic man-wrought mess.

When you're being earnest, people think you're being sarcastic and when you're being sarcastic, they think you're being earnest. The moral in all this, of course, is that people should never attempt to communicate.
