Your grades are not your destiny: they're just letters and numbers which rate how well you performed in one artificial arena, once.

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

I'm known as being a massive dweeb who's into video games and so on.

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.

[The rumor that David Cameron maybe once did this unspeakable thing with a pig's head] it was freakish and weird. It seemed such a coincidence that I couldn't quite process it. And then, as it sank in, I genuinely had the thought, "Am I living in a Truman Show sort of VR simulation designed to send me insane?"

[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.

Most of the books I read these days are children's books at bedtime.
