War bad, theatre good. That’s about the level of insight available from this amiable show, transferring after a successful run in Bath. It’s one of the weaker entries in the ever-popular backstage genre, sharing Vaudevillian DNA with Gypsy and a Nazi backdrop with Cabaret, but lacking the profundity of either. Though our girls bare all to stick it to Hitler, the drama remains skin-deep.

There will be blood. And expletives. And puppet sex that makes Avenue Q look positively monastic. But perhaps most shocking of all is that beneath the eye-wateringly explicit surface of Robert Askins’ provocative farce, which began life Off-Off-Broadway in 2011, lies a sentiment that makes this one of the cuddlier shows on the West End. Albeit one that features a graphically detached ear lobe.

Uncle Johnny instead of Vanya, a passing reference to sharia law, and nary a samovar in sight: surely this can't be the Uncle Vanya that has long been a cornerstone of the British theatre, especially in a new version from its take-no-prisoners director, Robert Icke, that presents the four-act text with three (!) intervals?

As a subject for drama, theatre history is always popular in the West End. Between Mr Foote’s Other Leg, which has recently closed at the Theatre Royal Haymarket, and Mrs Henderson Presents, which opens soon at the Noël Coward Theatre, comes Nell Gwynn, a West End transfer of the popular show from Shakespeare’s Globe, with Gemma Arterton as the eponymous heroine. But is this rowdy Restoration romp deserving of the lavish praise it has already garnered?

Jack is an alcoholic. Stephanie is a whore. Joseph is stupid. Stevie is a broody neurotic. These identifiers are proudly proclaimed in the first minute of Matthew Perry’s debut play, but if you weren’t paying attention, fear not: they will be repeated, loudly and often. This is theatre as group therapy, and there is nothing left to the imagination.

If one says, accurately, that Richard Bean’s Toast is a comedy about Hull’s lost bread industry, trade unions and the poor working man, you will possibly yawn and turn the page. But it is no more just about that than Henry IV, Part II is about Tudor pub culture. Toast is a gloriously madcap blast about men’s insecurities and pomposities, with a groanworthy taste in jokes.

Legendary director Peter Brook makes theatre that teaches audiences to be human. Now 90 years old, he brings his latest project to London from Paris, where he has been based at the Bouffes du Nord since quitting the UK more than 40 years ago. Called Battlefield, it is a 65-minute distillation of part of his 1985 11-hour epic, The Mahabharata, and revisits the ancient Sanskrit myth of the Kurukshetra War, and the struggle between the two warring families of the Kauravas and the Pandavas.

For a play about silence – its uncanny ability to tell the truth, to “persuade when speaking fails” – The Winter’s Tale is remarkably wordy. Of the sequence of late romances only Cymbeline comes close to the dense and elliptical verbal patterning we find ourselves tangled in here. But Michael Longhurst’s new production for the Sam Wanamaker Playhouse is so richly cast, its verse-speaking so expressive that we see straight through the often opaque text to the humanity and the humour beneath.

The death of a child is an unnatural loss. There’s no reassurance that the departed lived a full life, rather the jagged edge of one cut short. In the case of Becca and Howie, it’s also nonsensical: their perfectly healthy four-year-old son struck by a car in a freak accident while chasing their dog onto a quiet suburban street. How to find meaning in such absurd horror?

Demons, trolls and dead souls have a habit of latching onto Ibsen's bourgeois Norwegians. Surely the best way for actors to handle them is to keep it natural, make them part of the furniture and, in Dostoyevsky's words, "render the supernatural so real that one is almost forced to believe it". But very little seems real or spontaneous in Matthew Warchus's production of The Master Builder.
