The National Theatre’s triumphant march through its archive of NT Live recordings continues this week with a glorious blaze of a show. Starring Gillian Anderson, Ben Foster and Vanessa Kirby, this 2014 revival of Tennessee Williams’s 1947 modern classic A Streetcar Named Desire was a Young Vic production, and its film version is presented by National Theatre at Home.

A running gag in David Nicholls' novel The Understudy is that its main character is called Steve McQueen. Not that Steve McQueen, the multi-award-winning, critically acclaimed, rich and successful one. 

No, this Steve McQueen (Russell Tovey) is recently divorced, lives in a horrible studio apartment and has an acting career that is going nowhere. Then he lands the role of understudy to Josh Harper, aka the 12th sexiest man alive, making his West End debut in a serious role. Will his luck change?

Cats is, declares composer Andrew Lloyd Webber, a show that doesn’t really have a story, but was beloved on stage because it’s “the ultimate theatrical experience”.

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.

During lockdown, some of the best online theatre has been shows that are specially created for this digital format. Much better than dull records of dramas that might have worked well on stage, but now seem sadly moribund and exceedingly slow on the laptop screen.

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.

Are we really past all this? From Ivo van Hove's 2019 polyphony of opinions and reflections down the centuries, so much has gone into the oven on a low heat while more Brits discover that "better together" in the European Union might be a better catchphrase than "take back control". The flames will flare up again as the government finds it has no better way of mastering the Brexit problem than it has the C-19 crisis which has so ruthlessly exposed its unpreparedness.

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.

Maybe you can't compare incomparables, but it was instructive to watch this Broadway lockdown gala feting nonagenarian Stephen Sondheim a night after the Metropolitan Opera's galaxy of stars welcoming us into their homes.
