Maggie Smith is not only a national treasure, but every casting director's go-to old bat. Now 84 years young, she is our favourite grande dame, or fantasy grandma.

Theatre can give a voice to the voiceless – but at what cost? Abhishek Majumdar, who debuted at the Royal Court in 2013 with The Djinns of Eidgah – about the situation in Kashmir – returns with his latest play, Pah-La.

A loo with fuschia-pink carpet to catch splashback; an Archbishop of Canterbury who’s in it for the skirts; a gobbing Dorothy from The Wizard of Oz. A Jacobean theatre like the Sam Wanamaker Playhouse will have witnessed most extremes of human behaviour, but this soaringly irreverent, camper than tinsel, and – let’s face it - outrageously Eighties evening, takes it down alleys it’s never ventured before.

“We don’t love you any less.” A natural sentiment to express to your child when you’re separating from your partner, but the very fact of saying it plants doubts in the child’s mind as to whether you really mean it. As the audience of Wilderness at the Hampstead Theatre Downstairs, a new play written by Kellie Smith and directed by Hampstead regular Anna Ledwich, we feel Alistair’s doubts and fears keenly – mostly because we are him.

Caryl Churchill is a phenomenal artist. Not only has she written a huge body of work, but each play differs in both form and content from the previous one, and she has continued to write with enormous creative zest and flair well into her maturity. Now in her 80th year, she can look over her shoulder at a back-catalogue which is stuffed full of contemporary classics, and a handful of masterpieces.

The Crucible is a play that speaks with unrelenting power at times of discord, most of all when the public consciousness looks ripe for manipulation.

Wow, what a collection of talent: this show stars Peaky Blinder Cillian Murphy, and Enda Walsh's adaptation, Grief Is the Thing with Feathers, is based on Max Porter's award-winning novel of the same name.

In an age where political, social, and gender norms seem to be in perpetual meltdown, it should be pretty much impossible for a musical that begins with a song celebrating ‘Tradition’ to strike a chord. Yet from the moment that the cast of Trevor Nunn’s foot-stompingly fist-wavingly triumphant Fiddler on the Roof launches into the opening number, it’s clear that they have the energy and chutzpah to whip up an emotional storm.

“Cult” is probably an over-used adjective, especially when it comes to movies. But there’s undoubtedly something truly special about Bill Forsyth’s 1983 film – about a Texan oil executive on a mission to buy up a section of the Scottish coast for a vast new refinery, only to end up falling in love with the place – that makes it so warmly cherished by certain viewers.

Contemporary British theatre loves time travel — and not just to the past. It also enjoys imagining the future, especially the bad stuff ahead. So Ella Road's debut play, The Phlebotomist, is set in a convincingly coherent dystopia where genetic profiling reigns supreme, and one blood test can fuck up all your life chances.
