A ndy Field was midway through his standup run at this year’s Edinburgh fringe when he was struck by an unusual urge – the urge to draw a horse. “I hadn’t sat down to draw anything since I was at school,” says the 34-year-old comedian. “Drawing was a skill I didn’t have.”

He’s not lying. The subsequent horse Field posted to TikTok and Instagram was rather naive, with its four identical straight legs and cartoon eyeball. But the project he announced alongside it – Drawing a Horse Every Day Until I’m Really Good at Drawing Horses – immediately captured people’s hearts. Over a million people watched the minute-long video of him drawing that first horse with a four-colour ballpoint pen. By day three – an undeniably terrible effort in which the horse appeared to have sprouted a platypus’s bill – more than two million, by his estimation, had tuned in. “People were willing the series to continue,” says Field. And so he did.
