A British-Jamaican man is confused. It's the Second World War, and he signed up for the RAF on the understanding that he would serve as a pilot overseas. But instead he's ended up as ground crew in a grey Lincolnshire village. "You are overseas, aren't you?" sneers his sergeant.

As lockdown continues, National Theatre at Home has announced its final sequence of plays, and several of the very best are being saved for last. That certainly applies to this week's offering, Small Island, whose dissection of Britain's racist past couldn't be timelier.

As we continue into a third month in lockdown, the arts continue to suggest ever-changing worlds beyond. The invaluable National Theatre at Home this week looks across the Thames to a smaller venue's large-scale Coriolanus, starring a certain superhero movie icon, whilst the equally cherished Graeae streams their lively musical theatre tribute to the late Ian Dury.

There is a line of argument that – unfairly – blames playwright James Graham for Dominic Cummings. Would Cummings, some might ask, have achieved the influence he has now if it hadn’t been for his depiction in Graham’s brilliant TV drama Brexit: The Uncivil War in which he was played as an obsessive genius by Benedict Cumberbatch? 

Barber shops – as we are all starting to appreciate in this time of lockdown – fulfil an emotional as much as a cosmetic role: having a haircut can represent a new beginning, a moment for reflection, or even an informal confessional.

No one can accuse the gods of streaming of failing to cast a wide net. That's even more so with an array of streaming opportunities over the next week that ranges from Off West End Ibsen given a second chance to shine to an online encounter with, yes, The Encounter, and, should you wish, with its protean creator and leading man, as well.

Like an asp eating its own tail, the National Theatre's 2018 production of Antony and Cleopatra, streaming on YouTube until 14 May, begins as it will end. Director Simon Godwin's first tableau is the play's finale: Cleopatra (Sophie Okonedo) lies in queenly repose, a snakebite on her neck; her servants, Charmian (Gloria Obianyo) and Iras (Georgia Landers), slump around her.

Has anyone else noticed how fulltime this streaming thing has become?  Those who were of a mind to (and who never slept) could find enough cultural output to satisfy 24/7, especially if one adds to the free offerings that crop up by the week the ongoing back catalogue made available on sites such as Marquee TV or Digital Theatre, and the like.

So far, it could be said that the National Theatre is having a good lockdown. Every week, this flagship streams one of its stock of NT Live films, which are always a welcome reminder of the range of its output over the past decade or so.

Time is moving in mysterious ways at the moment. It's been possible over the last month or so to mark out the beginning of each week with the arrival online of a different production streaming from the Hampstead Theatre archives.
