Hi-def is merely the latest in a string of evolutional leaps that have transformed the way we sit slumped in front of a box wishing we were dead.

I would say the thing you can still see in Black Mirror is that I was probably traumatized by the specter of nuclear war. I was born in 1971, and in the '80s I came to understand that I was inevitably going to be frazzled to death in the nuclear apocalypse.

I'm convinced no one actually likes clubs. It's a conspiracy. We've been told they're cool and fun; that only "saddoes" dislike them. And no one in our pathetic little pre-apocalyptic timebubble wants to be labelled "sad" - it's like being officially declared worthless by the state. So we muster a grin and go out on the town in our millions.

"National Anthem" was just a funny idea I'd been knocking about. I initially thought about a beloved celebrity having to do that - and then I watched an episode of 24. In my head, I was writing almost a parody of a 24-style president woken in the middle of the night with a crisis. It seemed more interesting to play it ultrastraight and to have the viewer's initial reaction be one of laughter and disbelief - and just have the whole thing become progressively more uncomfortable.

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.

I'm quite geeky and I'm very much into video games and technology and stuff like that.

I can worry about anything.
