I can worry about anything.

I kept saying I want to do an episode that's set in the past, how do we do a period episode of Black Mirror? And simultaneously there was another idea we were thinking about and the two things sort of gelled and became San Junipero.

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

Seriously, if I switched on the TV and they were showing live footage of an army of fire-breathing pterodactyls machine-gunning people to death on the streets of London right outside my door, I'd be horrified, but not entirely surprised, nor any more scared than I already am. I'd probably just shrug and wait for them to smash the door down. We're so screwed, I don't even know what to worry about first.

The news might be single-handedly trying to bring about an environmental catastrophe, which it will then report on. Super injunctions are interesting legal weapons really, they don't just gag the press, they gag them from mentioning the existence of the gag. Sport belongs in a news bulletin about as much as a mummified cat's head belongs in a Caesar salad. Combine the "mounting pressure" with the "growing cause" and you've got yourself a "media whirlwind" which you can also refer to.

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.

It's a barrel of laughs, isn't it? It makes The Day After look like friggin'...insert name of cheerful thing here. It was one of the things that made me really worry about worst-case scenarios. There's something impish and probably somewhat therapeutic about thinking about those things.
