Theatre can touch thousands of lives. But can it compete with the success of a bestselling book? First published in 1988, mountaineer Joe Simpson's Touching the Void has apparently sold more than a million copies, and it's been translated into some 20 languages. It tells the adventure story of how he, and Simon Yates, climbed the Siula Grande peak in the Peruvian Andes in 1985. Last year, David Greig's stage adaptation of the book opened at the Bristol Old Vic, and then went on tour.

It’s been 15 years since Cameron Mackintosh’s stage musical version of P. L. Travers’ Mary Poppins made its West End debut.

It is 70 years since Willy Loman first paced a Broadway stage; 70 years since audiences were sucked into the vortex of a man trying to live America’s capitalist dream only to see his life crash and burn around him.

If ambition were all, Groan Ups would get an A*. Marking the first of a very welcome three-show residency at the Vaudeville Theatre, this latest from the cheerfully unstoppable Mischief Theatre tethers the japery we have come to expect from the team behind The Play That Goes Wrong  – mishaps aplenty, verbal hi-jinks  – with a newfound interest in the human psyche.

A hit comedy about a textile scientist? It might sound unlikely, but Ealing Studios’ 1951 sci-fi satire, starring Alec Guinness, was one of the most popular films of the year in Britain. Now, Sean Foley hopes to repeat its success with his new West End stage version, which tweaks the formula to go big, broad and occasionally Brexit-referencing – with varying results.

“Doors and sardines. Getting on, getting off. Getting the sardines on, getting the sardines off. That’s farce. That’s the theatre.

The work isn't finished on Big, if this stage musical of the beloved 1988 Tom Hanks film is ever to, um, make it big. A Broadway flop in 1996 where it was among the last shows directed by the late, much-admired Englishman Mike Ockrent, the material finds a sweetness in its West End incarnation that eluded it Stateside.

A tale of teenage depression and its family resonances, Florian Zeller’s The Son has a devastating simplicity. It’s the final part of a loose trilogy, following on from the playwright’s The Father and The Mother, but the new play eschews the obliquely experimental structure of its predecessors for something much more direct.

We're saying goodbye to a much treasured friend. Fleabag will live on, of course – other actresses have and will inhabit the role – but Phoebe Waller-Bridge, its creator, has said this short run at Wyndham's Theatre is the last time she will perform the character on stage.

One of the glories of contemporary London theatre is its revivals of classic American drama. Year after year, audiences are able to revisit and enjoy the great landmarks of postwar American playwriting from greats such as Arthur Miller, Tennessee Williams, Sam Shepard and David Mamet (recently joined by the likes of Lynn Nottage).
