What happens often is the script is written and once the director comes on board you have lots of conversations and it mutates again.

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.

If technology is a drug – and it does feel like a drug – then what, precisely, are the side-effects?

Being slagged off is good for you. It thickens the skin and strengthens the backbone.

I'm a worrier. In the UK, if I'm known for anything, it's sort of for being cynical.

I actually had that conversation with [Channel 4 Chief Creative Officer] Jay Hunt. We were at a bit of a crisis point. I'd written a totally different script - about war, basically - that got rejected at the last minute for various reasons. The whole of the series was in doubt. I said, "Well, there is one other idea ["National Anthem"]."

Whenever I tell people I'm a misanthrope they react as though that's a bad thing, the idiots. I live in London, for God's sake. Have you walked down Oxford Street recently? Misanthropy's the only thing that gets you through it. It's not a personality flaw, it's a skill.
