Society? Can we trust us? Doubt it. We're probably not even real, as was revealed in the popular documentary The Matrix. That bloke next door? Made of pixels. Your co-workers? Pixels. You? One pixel. One measly pixel. You haven't even got shoes, for Christ's sake.

I saw The Twilight Zone for the first time when I was 12 or 13. I used to stay up late to watch.

On the other hand [making a string of one-off episodes], there's a real freedom, because you're kind of reinventing the show every week.

[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.

What are people going to expect when they sit down to watch a new episode of Black Mirror? And what you're going to expect is somebody with a translucent TV in a drone strike and a robot walking by... or frowning at a phone and going 'aaah! Oh no! I've just deleted my own leg!' or whatever. So I thought well, let's not do that.

A sort of angry populism here in the UK and across Europe, a sort of anti-political mood and what then steps into that place? In one episode [of Black Mirror] you won't have seen, there's a very simple gaming gadget that turns out to be a monstrous idea, which I suspect we will end up doing for real.

'Waldo' was one episode I always felt I didn't quite crack. And weirdly, now that feels like one of the more prescient ones.
