Michael Socha is about to jump on a train to Wales. The impressively bushy beard he’s got is for his role in The Witch Farm, a dramatic adaptation of an episode of the Danny Robins podcast Uncanny, about a supposed haunting in the Brecon Beacons. He plays Bill Rich, who moves his family to a spooky old farmhouse where it all goes “horribly wrong”, Socha says. “In the photos he has a beard, and I thought, ‘I’ll match that.’” The actor strokes his chin and turns his head from side to side. It looks pretty substantial to me. “You say that, but see this bit? I’m struggling. It’s a bit patchy there. I’m happy with this bit, but then this needs work.”

Socha has just left a screening of his new BBC thriller The Cage, and he has the gentle bounce of a man who struggles to stay still. As with his beard, he finds it hard not to find flaws in what he’s done. Normally, he admits, he tries to avoid watching himself on screen. “I’ll sort of nitpick away,” he shrugs, but he had such a nice time making The Cage that he was looking forward to seeing it. “But the more you watch something, the more you find bits that you’re not too happy with.”

He has been hailed as the hardest-working writer in Britain. Looking at Jack Thorne’s astonishing list of credits, it’s hard to argue. The prolific playwright and screenwriter’s output includes many of the best homegrown TV dramas of the past two decades.

That’s without the many hit plays and films he has also written. There’s more to come, too. Next out of the Thorne pipeline is Channel 4’s forbidden romance Falling, with Keeley Hawes and Paapa Essiedu, and the film Enola Holmes 3, which will be followed by the small matter of Sam Mendes’ four Beatles biopics.
