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.

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.

I actually had that conversation with [Channel 4 Chief Creative Officer] Jay Hunt. We were at a bit of a crisis point. I'd written a totally different script - about war, basically - that got rejected at the last minute for various reasons. The whole of the series was in doubt. I said, "Well, there is one other idea ["National Anthem"]."

[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.

Hi-def is merely the latest in a string of evolutional leaps that have transformed the way we sit slumped in front of a box wishing we were dead.

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

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