[British television series] Hammer House of Horror. I used to really enjoy these one-off stories where often there would be an incredibly cruel twist. A good example is the episode with Burgess Meredith and there's a nuclear war and he drops his glasses. To this day, you can show that to anyone and they'll go "Bwrrrrrrrr!" You know, sort of wander away shuddering.

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.

There's something I find very satisfying about a nice ironic twist.

I'm a worrier. In the UK, if I'm known for anything, it's sort of for being cynical.

Obviously, you try not to repeat yourself so that forces you to re-evaluate what you're doing constantly [in Black Mirror].

I could worry that I'm going to bleed to death, you know, from cutting my finger on a sandwich packet, you know, if I sort of open a sandwich.

What are people going to expect when they sit down to watch a new episode of Black Mirror? And what you're going to expect is somebody with a translucent TV in a drone strike and a robot walking by... or frowning at a phone and going 'aaah! Oh no! I've just deleted my own leg!' or whatever. So I thought well, let's not do that.
