I think somebody's marketing a thing that Hoovers up your Twitter and it will continue tweeting for you after you're dead. I have no idea whether they saw "Be Right Back" or not.

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

I've always had a bad attention span.

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"]."

I've instinctively hated the Tories since birth.

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.

The iPad falls between two stools - not quite a laptop, not quite a smartphone. In other words, it's the spork of the electronic consumer goods world.
