“If we go to the theatre, it’s because we want to be surprised, even amazed.” Peter Brook’s programme note for The Valley of Astonishment stresses emotion and sensation above all things. How curious then that the play itself should be so cold, so cerebral a thing. In unpacking the mysterious valley of the human mind, Brook has become so engrossed in his subject matter and its scientific facts and phenomena that he forgets to add the drama that they need to move from lecture to theatre.

Theatre-maker Tim Crouch has a thing about art. One of his plays, ENGLAND, was performed in art galleries across the world; another was called An Oak Tree, after the 1973 conceptual art piece by Michael Craig-Martin. In fact, Crouch even looks like an arty type. Now, in his latest production, he tells a story about two fictional artists: Janet Adler and her lover Margaret Gibb. But, really, his main theme, as ever, is the relationship between art and reality.

A totemic play from (nearly) 20 years ago surfaces afresh in Stephen Daldry's West End revival of Skylight, the power of David Hare's intimate epic fully intact if somewhat redistributed as is to be expected from the passage of time and a new cast.

Director Nadia Fall has taken that patriarchal purveyor of footwear Henry Horatio Hobson and his family out of their natural habitat - a traditional proscenium arch theatre - and into a different time, the 1960s. Does this staple of British drama, written by Harold Brighouse in 1915 but set in 1880, benefit from relocation from plush indoor environs to the open air and from the era of button boots to sling-back stilettos? Up to a point.

Alex Webb’s musical Café Society Swing, about a provocatively liberal Manhattan jazz club in the 1940s, made a much-anticipated return to the Leicester Square Theatre last night. With remarkable ingenuity and economy, Webb tells the story of the real Café Society, a radical and subversive multi-faceted entertainment venue, which on opening in December 1938 was the first non-segregated club in America. It soon courted further controversy with Billie Holiday’s debut rendition of “Strange Fruit”.

If you've been rolling your eyes at the rash of articles hailing London's ever-increasing number of dry bars, allow writer-director Ché Walker to convince you of their amatory relevance. In his new musical drama, smooth-talker Klook and hard nut Vinette fall for one another over a long tall glass of carrot juice, with just the right kick of ginger. The Park Theatre's 90-seat studio space here gives us two sexy strangers who meet randomly in the grimy health club where Klook works, only to find that the two are craving a metaphorical detox. 

Sam Walters, Britain's longest-serving artistic director of a theatre (43 years!), looks to the past as well as the future with his Orange Tree swansong. This varied festival features nine plays and six world premieres across two programmes, all of them staged by returning graduates of the Richmond venue's trainee director scheme. The diligent Programme One viewer will spot a number of recurring subjects, including science teachers and astrophysicists, the resurfacing in adulthood of childhood dynamics, and constant grappling with faith and mortality.

In creating Mr Burns, Anne Washburn was trying to answer a question overlooked by most purveyors of dystopian fictions: what would happen to pop culture after an apocalypse? The physical and emotional challenges of life after civilisation have been endlessly explored, but very little attention has been paid to the fate of the ever-evolving collection of stories that we carry inside our heads.

Some days, I feel very sorry for playwrights, especially those that become notorious through no fault of their own. If their most famous play causes enough controversy, it can take decades before people forget it. So now, 10 years since Gurpreet Kaur Bhatti’s early play, Behtzi (Dishonour) caused violent protests at the Birmingham Rep because of its depiction of a rape in a Sikh temple, I can’t think of any other way of starting this review of her latest without mentioning it.

Brian Friel’s affinity with Russian writers, notably Chekhov and Turgenev, is central to his work, the playwright seeing similarities between their tragi-comic characters, hanging onto “old certainties” despite knowing in their hearts that their time is up, and people of his own generation in Ireland. The correspondences go beyond theme, of course; he’s not known as the Irish Chekhov for nothing.
