[Black Mirror] is always about unforeseen consequences and unforeseen problems, it's not usually that someone's created a machine that they want to enslave mankind with, it's someone's invented a new kind of... paperweight that enslaves mankind.

Technology is a global thing and wherever you go, people are prodding the same devices and worrying in the same way and have had their lives slightly altered in the same way.

Everyone had clearly spent far too long perfecting their appearance. I used to feel intimidated by people like this; now I see them as walking insecurity beacons, slaves to the perceived judgment of others, trapped within a self- perpetuating circle of crushing status anxiety.

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.

My kids are very young. I'm sure there's a world of horror for me to worry about as they get older.

It's interesting, in the U.K., I'm known for doing comedy things, which often doesn't translate to the U.S.
