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.

I did once leave one of [my kid] watching something on YouTube, something completely innocuous, and I went out of the room and the algorithm kept playing the next thing and the next thing and somehow worked its way around to showing him the trailer for John Carpenter's The Thing - at which point I walked back in. He wasn't happy.

Most writers or performers walk around with the notion in their head that - a paranoid worry that maybe people don't like them.

I think overseas viewers assume that Black Mirror is written by the Unabomber, essentially - a Ludd­ite, technology-hating, angry old man waving his fist at the App Store.

I'll just immediately automatically, without even thinking, check my phone. And it feels like the same little bit of my brain is being - the synapses are lighting up when I do that.

Man the lifeboats. The idiots are winning.

What is useful about when there is a sort of pull-out to reveal moment going on is that it actually focuses the mind when you're writing the earlier scenes because you're thinking 'right, how do I? I can only show this amount of the room... I can only show these characters from the waist up because they've all got robot legs!' it's a challenge so it keeps you engaged on some level.
