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

I'm not some anti-technology person. I think it's often how people would assume that if they don't know me.

I was more aware initially of shows like Tales of the Unexpected. And the BBC used to put on a lot of one-off, bizarre television plays.

Men Against Jive is a brilliant title! That's a military story, that's a difficult one to explain really because that's sort of a war... it's not just a war story.

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.

What we were also trying to do is vary the tone slightly across the season of Black Mirror, because there are six stories this time around, so you don't want it to just be the devastating, bleak-em-up.

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.
