You have to hand it to Menier Chocolate Factory, a venue that doesn't let size matter as it stages an all-singing, all-dancing new production of Barnum, a musical about Phineas Taylor (PT) Barnum – the 19th-century showman famed for staging “The Greatest Show on Earth”.

The political story of our time is the upsurge in support for Jeremy Corbyn, leftwing leader of the Labour Party, mainly by young activists who are both idealistic and energetic. But what would happen if one of them decided to go freelance, and pushed their protest beyond the bounds of reason? James Fritz’s resonant and beautifully structured play explores this kind of question.

Confused people, some of whom may have made the wrong choices in life and love, find themselves in an enchanted wood at Midsummer. Dear Brutus has long been seen to echo Shakespeare’s comedy of metamorphosis, A Midsummer Night’s Dream. A huge success in 1917, it is rarely performed now, and Barrie’s fantasy for grown-ups is probably more of a challenge to the modern director than its Elizabethan precursor.

Even by the standards of theatrical archaeology that the Finborough has made its own, The Passing of the Third Floor Back is a curiosity. Jerome K Jerome’s 1908 play was a long-running hit in the West End – with Johnston Forbes-Robertson, one of the leading English classical actors of his day, in the lead – before transferring to Broadway for a year.

The civil war in Syria spawns image after image of hell on earth. Staging the stories of that conflict presents a challenge to playwrights: how do you write about horror in a way that is both accurate and entertaining? Goats, by Syrian playwright and documentary film-maker Liwaa Yazji, translated by Katharine Halls, is part of the Royal Court’s international project with writers from Syria and Lebanon, and takes up this challenge.

Fresh from the success of Harry Potter and the Cursed Child, Jack Thorne now gives us his exuberant adaptation of another much-loved text. Charles Dickens’ novella A Christmas Carol is the well-worn morality fable seared into our collective memory by countless screen versions and stage musicals.

You say you want a revolution? Good luck locating one amid the tonally muddled Inside Pussy Riot. The immersive production from Les Enfants Terribles takes audiences on a promenade-style journey through the terrifyingly true story of Nadya Tolokonnikova, the Russian activist who (along with bandmate Maria Alyokhina) was sentenced to two years in a Siberian prison in 2012 after performing 40 seconds of an anti-Putin protest song in a Moscow church.

The Globe’s Sam Wanamaker Playhouse may be a historical recreation, but the same shouldn’t be true of the plays staged within it. Since it opened in 2014, this atmospheric space has spawned a whole sub-genre of historical new-writing – works that have too often been respectfully inert, struggling to find a contemporary voice among so much authenticity.
