I grew up in the countryside . But there's a danger of us romanticizing that. Because when I was a kid in 1982, that's what my parents were saying to me about television and comics and computer games!

Generally I know that we've hit on a good idea if there's a moment where I'm going "HA HA HA!" because that's usually my starting point, me laughing.

I'm trying to think overall. Some of our stories [Black Mirror], I think you're right in that they don't tend to have a message.

I pitched Jay Hunt the opening scene (prime minister, middle of the night, he's woken up...). She paused, and then she laughed. She was very intrigued and all that, and then she said, "Does it have to be a pig?" So we went through various options: Could it be a supermarket frozen chicken? A giant wheel of cheese? A pig seemed just the right level of absurd, but then when he walks in and there's actually a pig there, it's awful.

Things like social media and the Internet, of course, it's not going away. There is no cure for it. And this shouldn't be just like there shouldn't be, you know - it would have been a tragedy if there was a cure for the printing press. I think it's just that it's an amazing tool that we as a - as an animal are just getting to grips with because it's like we've grown a new ultra powerful limb and we're learning how to use it.

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'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.
