I really don't want to sound like overly negative or critical of the Internet in general because I'm actually really quite pro-technology.

My theory is that we used to have several personalities, and now we're encouraged to have one online.

Our four-year-old, like a lot of kids, you introduce him to an iPad and he quite quickly gets drawn in in a way that you're like, "Wow, I've got to stage an intervention here." He picked up on gaming terminology really quickly. If you say, "Keep practicing holding a pencil and see if you can draw a letter, the alphabet," he understands that if you do that you've unlocked Level Two.

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.

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.

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've always had a bad attention span.
