When I meet Charlie Brooker over breakfast at a café in Ealing – he has porridge, with bananas that he "hopes are caramelised and not mouldy" – he's feeling pretty tired.

Not only has he been up all night tending to a sick child, he's also recently been on location filming the new season of his Bafta-nominated, technology-inspired series Black Mirror – and he still has two episodes left to write.

A natural-born worrier, the TV writer, presenter and satirist is also feeling fairly pessimistic about the state of the world right now, although he's simultaneously finding grim humour in the way that real life appears to be morphing into a particularly surreal Black Mirror episode.

Here's what Brooker had to say about the forthcoming fourth season of the show, working with Jodie Foster (who is directing one of the new episodes), the rise of Donald Trump, and the widespread appeal of San Junipero, the unexpectedly emotional season three love story that left many viewers in floods of tears last year.
