A lot of people are going to be enraged, frustrated, or confused by Evening at The Talk House, and in the authorial world of Wallace Shawn, wasn't it ever thus? This is the playwright who gave pride of place to a softly-spoken fascist in Aunt Dan and Lemon and challenged his audience's complacency directly with The Fever, so if I say that his latest play is of a piece with his earlier ones, that is intended as high praise, indeed.

Hollywood took 365 speaking parts, 50,000 extras and 2,500 horses to tell this epic tale in 1959; here at the Tricycle, it’s a cast of four and some enterprising puppet work. Playwright Patrick Barlow, following up global hit The 39 Steps, has chosen a comic contrast that could hardly be equalled: redux maximus.

Welcome to the hellmouth. In Jamie Lloyd’s startling 50^th anniversary revival, the seething, primal hinterland of Pinter’s domestic conflict is made flesh: the metal cage surrounding an innocuous living room glows a devilish red, sulphur-like smoke belches from the ether, and snatches of Sixties music distort into horror film cacophony. Purists may carp, but it gives a long-revered play a welcome shot of adrenaline.

RD (“Ronnie”) Laing was a typically eccentric 1960s guru. A Scottish psychiatrist who was one of the leading lights of the anti-psychiatry movement, his 1960 classic The Divided Self helped a whole generation to a deeper understanding of mental illness and especially the experience of psychosis.

In the world of dramatic rediscoveries, half a century may not count as a long time. Slightly more, in fact, with Robert Bolt’s first performed play Flowering Cherry, which premiered in 1957 with Ralph Richardson and Celia Johnson in the leads as the eponymous husband and wife, Jim and Isobel Cherry.

Derren Brown calls himself a mentalist, but he's also a great showman, as his latest show, Miracle, attests. With its simple set, this is seemingly an evening of straightforward illusions. But that's deceptive, as Brown provides more than two hours of intricately constructed theatre that has a very big message – that humans have the power within ourselves to change our lives, and to heal ourselves.

Pro patria mori. Now there’s the test for Henry V - perform it on Remembrance Day. The “band of brothers” shtick relies on an idea of patriotism from an age when there was no need to define something so heartfelt, and an idea that kings and commoners were all in it together when fighting the enemy. After all, Henry orders the good English soldiers to rape French girls, smash the heads of French grandfathers, and skewer their babies on pikes, no questions asked. The bonuses of patriotism, if you like.

Teenagers lie – that’s nothing new. But are the activities they’re concealing from anxious parents in this oversharing digital age more extreme, more likely to define their lives and those of the people around them? James Fritz’s 90-minute debut, the first of two Hampstead Downstairs transfers to Trafalgar Studios, dives headfirst into that murky paranoia, with dramatically mixed but thought-provoking results.

One of the quiet joys of contemporary British theatre is the small play. You know the kind of thing: a boy-meets-girl story, told with sharp dialogue and quirky humour. Usually with a cast of two, this type of play is fast-moving, full of small incident, but with larger themes thrown up like shadows on the wall behind the action. Staged in small studio theatres, they are usually short adventures in new writing, with a bittersweet twist. At first, it looks like Andrew Muir’s The Session fits this bill like a woolly sock on a cold foot.

Do scandals have a sell-by date? When it comes to sex and politicians, the answer is no. The tabloids, and the news-hungry public, still seem to relish a good story about a powerful man who is caught with his trousers around his ankles. So Harley Granville Barker’s Waste – first put on in 1907 and then rewritten some 20 years later – is ostensibly a highly relevant drama of a personal tragedy in which our characteristic national mix of prurience and puritanism gets a longwinded airing. Certainly, the plot is instantly recognisable.
