Prolific writer Mike Bartlett is the most impressive penman to have emerged in British theatre in the past decade. The trouble is that his work is so uneven. Although he wrote the amazingly imaginative play, Earthquakes in London, and the Shakespearean West End hit, King Charles III, he has also been responsible for the preposterous improbabilities of the second series of the BBC’s Doctor Foster.

In a rather clever wheeze, Dominic Dromgoole, former artistic director of Shakespeare's Globe – who therefore knows a thing or two about historically accurate stagings – has established Classic Spring, a new company dedicated to celebrating work by “proscenium playwrights” and staging their plays in the theatres they were written for.

Loneliness: in the age of the digital hook-up and the flaunting narcissism of social media, it’s become a strange sort of taboo – a secret shame, the unsexy side of singledom. So it’s good to see playwright David Eldridge putting it centre-stage in this tender, pleasingly unsentimental two-hander.

The awful mother, the celebrity-obsessed teenager, the mediocre old writer who wants some young sex in his life – there are motifs in Chekhov’s The Seagull that fly merrily from one century to another, and Simon Stephens and Sean Holmes’ new modern-dress update for the Lyric, starring Lesley Sharp, is fresh and acco

God makes few appearances at the modern playhouse – so few that the Finborough Theatre saw fit to print a glossary in the programme for its latest production. What begins with Agnostic, Annunciation and Aramaic runs all the way to Spirit Guide, Utopia and Vespers, which gives some idea of the breadth of reference to be found in this tightly constructed three-hander by New York writer Keith Bunin.

What a difference an ocean and a change of scale can make. When I saw the Mel Brooks musical Young Frankenstein on Broadway a decade ago, the show seemed to take its cue from the lumbering monster contained within it, who stutters and sputters before eventually being kickstarted into something resembling life.

Bold and fearless are adjectives that might describe playwright Rory Mullarkey as accurately as any chivalrous knight. He made his name in 2013 when, at the age of 25, his play Cannibals, part of which was in Russian, took to the main stage at the Manchester Royal Exchange and went on to win the James Tait Black Prize. He has written opera libretti, a play about revolution for the Royal Court, The Wolf from the Door, and a version of The Oresteia for the Globe.

Playwright Simon Stephens and director Marianne Elliott are hyped as a winning partnership. Their previous collaborations include The Curious Incident of the Dog in the Night-Time, a massive Olivier award-winning hit, and her sensitive revival of his early play, Port, at the National Theatre.

What does it mean to feel contemporary? Feel. Contemporary. According to theatre-maker Chris Thorpe, whose new play Victory Condition has just opened at the Royal Court in tandem with Guillermo Calderón’s B, being contemporary is a really disturbing mixture of feeling all-powerful and completely powerless.

A year after premiering acclaimed French playwright Florian Zeller’s The Truth, the Menier Chocolate Factory now hosts The Lie – which, as the name suggests, acts as a companion piece of sorts.
