Your response to Barney Norris’s one-man play, based on David Foenkinos’s bestselling novel as translated by Megan Jones, probably depends on which of the Gens is yours. 

Alexei Sayle, in his angry young man phase, once said that you can always tell when you’re watching a Shakespeare comedy, because NOBODY'S LAUGHING. That’s not entirely true, of course, but sometimes a director has to go looking for the LOLs and make a few sacrifices along the way in their pursuit. And, boy, oh boy, does Sean Holmes go looking for the laughs in this production of The Tempest – and don’t we suffer a few sacrifices as a consequence.

Two years after the release of Fantastic Beasts and Where to Find Them, we return to the Wizarding World once again for the next, somewhat convoluted, chapter in the five planned prequel instalments, with Fantastic Beasts: The Crimes of Grindelwald.

London’s Palace Theatre this week celebrated the thousandth performance of Harry Potter and the Cursed Child, which opened there back in 2016. Like everything else JK Rowing puts her hand to, it’s been an outrageous success, taking the post-Hogwarts wizarding world further into the future than any other part of the franchise.

Imagine an orchestral concert made up exclusively of contemporary works by living composers: a programme in which every note was written within the last two decades. Imagine not only that this concert is sufficiently popular to fill a 2,000-seat hall with a noticeably youthful and diverse crowd, but that its format is already being replicated regularly by pretty much every major UK symphony orchestra. Now ask yourself how much critical attention such a concert would receive? You wouldn’t be able to pick up the Sunday review supplements for sheer weight of coverage, would you?

Harry Potter has a lot to answer for. The phenomenal success of JK Rowling’s books, and of their film versions, and of the stage play (now set to remain in the West End for all eternity), has created a template of extravagant cultural impact that must still be bewitching prospective authors of the next big thing, as well as their prospective publishers and prospective readers.

Harry Potter has a track record of trickery. He miraculously persuaded a generation of screen addicts to get stuck into hardbacks. Lately he has been luring multiplex junkies into the theatre to see live wizards on stage. Can Harry Potter make it a hat trick by coaxing his fans into a gallery? Harry Potter: A History of Magic is at the British Library.

There’s a new ‘tec in town. Cormoran Strike may look like one of life’s losers – he’s on the edge of bankruptcy, sleeps in the office, and what passes for a personal life is a right mess – but in Tom Burke’s portrayal I suspect he’s going to be winning audiences in a big way. He’s the creation, of course, of JK Rowling, writing as Robert Galbraith – the author’s chosen anonymity lasted barely three months – and her debut in crime writing is now a satisfyingly stylish BBC adaptation.

Name seven students in Ravenclaw. Which 14 subjects are on the syllabus at Hogwarts? Create a shopping list of 20 different types of magical sweet. In her Harry Potter stories JK Rowling conjured up an almanack of wizarding facts and figures which, for parents, proved extremely useful during long car journeys or steep mountain climbs (even if this parent didn’t know all the answers). A handy staple was “List 16 magical creatures”. It would keep them going for hours because, if memory serves, Rowling created only 14 of them.

David Yates is not the best-known film director in the world, but he has been at the helm of four of the most successful. All of them had “Harry Potter and the” in the title. After the last Potter movie he took a break among the computer-generated jungle foliage of The Legend of Tarzan, but he’s now back working in the service of JK Rowling’s imagination with Fantastic Beasts and Where to Find Them.
