What's in a name? Imogen has a softer music to it than Cymbeline, the only one of Shakespeare's plays in which the title character is marginal, and the daughter certainly dominates in a way that her regal father doesn't. So Cymbeline Renamed, as half the subheading of Matthew Dunster's bold production puts it, is fine.

At its best, theatre is great at putting resonant metaphors on stage. And, as Elinor Cook’s new play abundantly proves, the activity of mountain climbing seems very promising as a metaphor for masculine endeavor. All that effort, all that heaving, all that straining. Blood and sweat and sometimes tears. And then the question: why do men want to stand on top of the world? And is it just men who have this urgent need for power and dominion?

Very occasionally the playing of a play leaves a deeper impression than does the play itself. This is the case with Good Canary, a lippy, sweary tragicomedy by Zach Helm about secrets and addiction on the New York publishing scene. It has already played in translation in Mexico and in France, where it won Molière awards for direction and design. Its director, the prolific screen and stage actor John Malkovich, now brings it to London for the first time – and obligingly lends his famously dark-chocolate tones to the reminder to turn off mobile phones.

Michael Head's new play is based on the book They Took the Lead by Stephen Jenkins, which tells the true story of events at Clapton Orient (now Leyton Orient) Football Club during the First World War, when 41 men associated with the east London team – players, backroom staff and supporters – joined up en masse to fight the Kaiser. Three never returned and several others were seriously injured.

We are lost in the wood. In the limbo state between dream and reality, memory and present, youth and age, companionship and seclusion, life and death, struggle and success, fame and obscurity. Pinter often visits that place of in between, but the elusive and haunting No Man’s Land – electrifyingly presented by two of our greatest thespians – dwells deep within it.

Growing up is a kind of grief: losing the person you once were to embrace the person you will become. That loss can fracture familial relationships, forced to adjust and reform as offspring alter, challenge, question and move away – physically, emotionally or both.

The confidence trick to end all tricks, Ben Jonson’s The Alchemist is so utterly recognisable, so clearly contemporary, that to update the setting feels a bit like underlining the point in red pen. In this transfer from Stratford's Swan Theatre director Polly Findlay plays things 17^th-century straight, allowing her audience to make the connection with just a little help from an irreverent new epilogue.

The family is a war zone. Bam, bam, bam. For some people, it can be the most dangerous place on earth. Its weapons include domination and betrayal, blackmail and abuse, and its frontline is memory – what really happened, and who is most to blame? In actor-playwright Nathaniel Martello-White’s new drama, this war zone is crossed and re-crossed with passionate vigour in a minimalist production that has some strong points and some frustrating aspects too.

What price a human soul? That’s the question Marlowe’s Doctor Faustus asks – a question whose answers are rooted in faith and theology. But in a society with little use for faith and still less for theology, how do you reframe the question? Director Maria Aberg offers a deft if not always entirely coherent answer in her breathless, punky take on the play for the RSC.

We’re living in the age of the small play. Although there are plenty of baggy epics around on our stages, they are outnumbered by the small and short two-hander, whether it's John O’Donovan’s gloriously titled If We Got Some More Cocaine I Could Show You How I Love You at the Old Red Lion or the equally gloriously acted Counting Stars by Atiha Sen Gupta at Theatre Royal Stratford East. And, sure enough, the latest new play at the ever-enterprising Orange Tree, Zoe Cooper’s Jess and Joe Forever, is small and short. But it is also a hugely enjoyable romcom.
