"Love comes now. You have to start with love," urges Sarah Kahn (Samantha Spiro) early in Chicken Soup With Barley, and it's inconceivable that Dominic Cooke's knockout production of Arnold Wesker's 1958 play could have sprung from any other starting point. There's talk later in Wesker's three acts (taken here with only one interval) of seeing people in the round, which is exactly what the writing, not to mention Cooke's superlative ensemble, manages to do: the political and the personal conjoined in a compassion that one might describe as clear-eyed if only it didn't prompt from an audience such honestly earned tears.

Ben Butley is poisonous, spiteful, a bully, a sadist and a snob. So how does Simon Gray, who created his titular anti-hero in 1971, ensure that an audience can endure his company? He equips him with the kind of lacerating verbal dexterity that makes you catch your breath, appalled and a little awed all at once. And in Lindsay Posner’s fine revival, this nasty, sad, desperate piece of work who, as a lecturer in a London university English department, gets plenty of opportunity to inflict his wit on the soft young sensibilities of eager undergraduates, is played with bilious aplomb by Dominic West. You dislike him, often violently; but you can’t tear your eyes away from him.

Verbatim theatre has been the flavour of political theatre for the past two decades, and no theatre has done more to promote this style of public witnessing than the Tricycle in Kilburn, north London. Its artistic director, Nicolas Kent, has created a special style of verbatim drama called tribunal theatre, where the results of long-running public inquiries or trials are edited into an evening’s viewing. His latest venture, Tactical Questioning: Scenes from the Baha Mousa Inquiry, which opened last night, illustrates the pros and cons of this type of infotainment.

“Where once was certainty is now only void.” The age of John Donne was also the age of Galileo, Milton, of Hobbes, Francis Bacon and, of course, the King James Bible, whose 400th anniversary we celebrate this year. At the intersection of politics, religion and scientific philosophy, Donne’s life under James I holds up a mirror to the conflicted age that produced this extraordinary work of scholarship. Meshing the poet’s biography, his work and social history, Jonathan Holmes has produced a play whose scholarship and subject matter may be serious, but whose theatricality is poignantly, evocatively and, at times, even erotically handled.

If a great whorl of bubblegum were plonked on Trafalgar Square's fourth plinth all summer long, would there be any point in complaining about it? How do you criticise the uncriticisable? A new Much Ado About Nothing at Wyndham's is Shakespeare-by-television: failsafe. As theartsdesk has recently pointed out, there is the "other production" at the Globe, which celeb chatter over and vast publicity for this brassy West End one have conspired to relegate to a sideshow somewhere obscure south of the Thames.

Everybody’s talking about Much Ado About Nothing. At dinner tables, the pub and on the Bakerloo Line the only cultural conversation to be overheard having is whether David Tennant and Catherine Tate will be as wonderful as we all want them to be as Shakespeare’s feuding lovers Beatrice and Benedick. Their West End show opens next week, and among all the hype and headlines another production (and it was always going to be the “other production”) has quietly opened down at Bankside – a show with such warmth and knockabout energy that if Tate and Tennant are not very brilliant indeed they may find themselves outpaced.

With The Cherry Orchard just opened at the National Theatre and The School for Scandal at the Barbican, summer is quickly proving itself the season for classic theatrical revivals. The latest to join the London line-up is Shaw’s perennially beloved comedy of love and the English language, Pygmalion. Debuted at at the Chichester Festival Theatre last July, Philip Prowse’s traditional production returns a year on with a West End home and some starry new cast members, hoping to charm fresh audiences with this oldest of theatrical fairytales.

Dropped trousers, audience participation and an onstage skiffle band fronted by a singer/songwriter boasting specs by way of Buddy Holly: what has become of the National Theatre's Lyttelton auditorium? Well, let's just say that for the entire first act of One Man, Two Guvnors, it's got to be easily the giddiest theatrical address in town. And when the momentum flags, as it does somewhat after the interval, not to worry. By that point, Richard Bean's Goldoni rewrite has generated enough goodwill that you all but float home.

Anya Reiss must be the most precocious playwright in London. Her 2010 debut, Spur of the Moment, written while she was just 17 and still studying for her A levels, won two Most Promising Playwright awards, from the London Evening Standard and the Critics’ Circle.

"There’s no possibility of being witty without a little ill-nature,” preaches the Gospel according to Richard Brinsley Sheridan. What the playwright omits to mention, however, is that it is possible to be ill-natured without in fact being terribly witty, a flaw that proves almost fatal for Warner’s acerbic, alienated new production of The School for Scandal. Overstyling Sheridan’s most stylised of comedies, Warner turns what Hazlitt described as the most “finished and faultless” play into a mass of tensions, exaggerations and contradictions. The result can be exhilarating in the moment, but wears off into confusion and a slight headache.
