A caption tells us that while filming the Beatles at Twickenham Film Studios in January 1969 for a planned TV broadcast, director Michael Lindsay-Hogg and his crew amassed 60 hours of film and 150 hours of audio recordings. Some of it was seen in the 1970 film Let It Be, but the bulk of it has remained locked in the vaults ever since. Until now.

One of the absolute highpoints of new writing in the past couple of years has been the Death of England trilogy. Written by Roy Williams and Clint Dyer, these three brilliant monologues have not only explored vital questions of race and racism, identity and belonging, but have also provided a record of theatre-going before, during and after the pandemic lockdown.

“Drug companies are supposed to be honest,” says a lady from the Department of Justice, explaining why the US Food and Drug Administration had been treating the pharmaceutical industry with a light, indeed barely detectable, regulatory touch.

Conceived on a global scale to depict the enormity of an alien menace from outer space, Apple's new series Invasion has grand ambitions, but crash-lands like a pile of space junk. After a few hours of this, waiting for something to happen, you’ll be yearning for a trawl through Netflix or Walter Presents.

Channel 5’ s decision to remake James Herriot’s much-loved Yorkshire vet stories was an inspired one, and this second series has effortlessly carried on the mood of gentle observation, nostalgia and slapstick comedy amid scintillating Yorkshire Dales scenery. A teeming cast of dogs, cats, horses, cows and chickens is permanently on call to provide fuel for the adventures of Herriot and the Farnon veterinary dynasty.

This Korean-made show suddenly became Netflix’s all-time greatest hit, demonstrating once again the irresistible allure of a game show which ruthlessly massacres its contestants. Squid Game has some fairly obvious antecedents – for instance The Hunger Games, the Schwarzenegger vehicle The Running Man and the Japanese TV show Battle Royale – and also carries echoes of the 1960s cult mystery The Prisoner and perhaps a soupçon of Lord of the Flies.
