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.

"One... Two... You know what to do": that coolly delivered rehearsal intro from a trombonist called Cutler (Clint Dyer) could serve as a synoptic appraisal of the simply overwhelming National Theatre revival of Ma Rainey's Black Bottom. The play in 1984 launched the late August Wilson on to Broadway, where I first saw it, and here announces itself as a bellwether achievement in artistic director Rufus Norris's still-young National Theatre regime and as, very possibly, the finest Ma Rainey yet.

Lolita Chakrabarti’s impassioned debut has only gained topicality since its 2012 Tricycle incarnation. Trevor Nunn’s all-white Wars of the Roses and #OscarsSoWhite, among others, have fanned its flames, while quips about a paranoid Russian regime and the limits of English openness to change seem all too pertinent. Cameron might well borrow the woolly idea of “new based on the old” during the European referendum debate.

You might think that the combination of a play about one of the funniest comics of the second half of the 20th century, written by his biographer and directed by a member of Monty Python would be a winning one. But sadly Robert Ross's Jeepers Creepers: Through the Eyes of Marty Feldman is anything but.

Caryl Churchill is a phenomenon. Now 77 years old, she remains not only prolific but also immensely inventive, having notched up more than 35 original plays, many of which have been innovative in form and imaginative in content. Added to this, she has penned dramas for radio and television, as well as adaptations of the classics. She also retains the power to annoy: the National Theatre staging of her Here We Go last autumn provoked walkouts and howls of critical derision. So what’s her latest like?

Anne longs for her 23-year-old son Nicholas to return home. One night, he appears. Or does he? Welcome back to the queasily elliptical world of Florian Zeller, where certainty fractures as familiar elements are repeated, dissected, made strange and menacing. Zeller used this immersive dislocation to powerfully communicate the experience of dementia in The Father, which last year travelled from Theatre Royal Bath to the Tricycle and on into the West End.
