The clipped Fifties accents raise a smile for the first few minutes, but what’s startling about this new production of Terence Rattigan’s 1952 play is how universal, how timeless the story is. Director Sarah Esdaile wisely decides to play things respectfully straight, and within seconds the time and place, both beautifully evoked in Ruari Murchison’s detailed set, melted into irrelevance.

Just in time to capitalise - is that how that word is spelled? - on awards season, along comes the latest Broadway-to-Britain transplant, The 25th Annual Putnam County Spelling Bee, a musical all about a culture that likes to win, win, WIN! Does William Finn and Rachel Sheinkin's surprise 2005 New York hit go to the top of the London class?  Intermittently, yes. Charming and cheeky at its best, repetitive and sentimental elsewhere, the piece may simply be too echt-American to repeat its success here, though it certainly marks a change at the Donmar from the daunting fare this playhouse has favoured of late.

Forked lightning glimpsed through an aeroplane window, a silken dancer spilling stars in a snow-filled sky, a dragon tattoo etched on a man’s back: we’ve grown to expect seductive alchemy of images from the work of Quebecois master of visual theatre Robert Lepage, and in his latest show he doesn’t disappoint.

Men. They say these strange creatures never leave the playground. Even when the years have passed, boys stubbornly remain boys, chatting rubbish, competing manfully and finally burning out. In Enda Walsh’s Penelope, which was a hit at the Edinburgh Festival last year and now visits London, four men compete for the love of one woman, and they are as likely to be found bickering over a small barbecued sausage as they are to be seen fighting to the death with knives. The only question is: can they also work together?

From being virtually ignored by theatres and playwrights, the issue of climate change now threatens to swamp the programmes of our flagship theatres. If this is a good thing, meaning that the heat has been turned up on the debate, can public interest be maintained at this rate? Is the topic at all sustainable? After Greenland opened at the National Theatre last week, now it’s the turn of Richard Bean’s new play, which had its premiere at the Royal Court last night, in a production starring the superb Juliet Stevenson. And if the National's contribution to the debate was a bit too cool, Bean's play is much hotter.

Who needs America for the American theatre? Barely six weeks into this year, and already we've had the bracing and bilious Becky Shaw, the West End transfer of Bruce Norris's perpetually award-scooping Clybourne Park and Woody Guthrie taking up residence at the Arts Theatre courtesy of Woody Sez. What's been lacking has been the sort of defining revival on the order of last season's All My Sons that shakes down an extant text, inducing in sometimes unruly West End audiences a wondrous hush.

A whiff of excrement hangs around DBC Pierre’s Booker Prize-winning Vernon God Little. It’s a novel that likes to get right up into the crevices of society and then inhale deeply. Written in an anarchic, freewheeling American patois, it’s the inner voice of Vernon himself (and Pierre’s brutal way with a simile) that plays shock and awe with the reader, delighting many and appalling more. The loss of narrative voice would seem enough to deter any would-be theatrical adaptor, but in 2007 Tanya Ronder and the Young Vic took up the challenge. The result (newly revised) now makes a return – shotgun in one hand, the other down its trousers.

Theatre, particularly tragedy, can pack a terrific punch when things are kept simple – even if the themes evoked are enfolded in layer upon layer of complexity. Brian Friel’s Faith Healer, a play with three characters, each of whom takes to the stage alone, explores in a multifaceted way the life of an itinerant Irish healer who plies his trade along the backroads of the Celtic fringes of Britain.

Emlyn Williams may have been dubbed the “Welsh Noël Coward” and the action of his long-neglected Accolade may take place in a drawing room, but there’s little of the smiling social comedy to be found here. Trading sparkling cocktails and repartee for whisky and unpalatable truths, Williams’s play exposes the pinstriped hypocrisy of 1950s society – a society that will press its powdered cheek to all manner of sordidness in the name of Art, while recoiling from even a passing acquaintance with the workaday squalor of its members. Frank, and more than a little apt, the result is a stylish morality play that smuggles a progressive liberal agenda in under its cassock.
