We remember JM Barrie as the creator of Peter Pan, that quintessentially English fairy story which features Neverland, the Boy Who Wouldn’t Grow Up, and where “to die would be an awfully big adventure”. Generations have embraced this mythical tale as an expression of the spirit of upper-class Deep England. Here the Victorians are us. But James Matthew Barrie himself was the child of a Scottish Calvinist working-class family, and is the subject of Alexander Wright’s play — a hit in Edinburgh last year — which aspires to be a kind of anti-myth.

The world of the media offers plenty of opportunities for satire, but the idea of a comedy about sub-editors at first glance seems odd. After all, the sub-editors, or subs, are hardly journalism’s most glamorous beings: these office-bound nerds spend their working days correcting the spellings of journalists and cutting their copy, while penning pun-heavy headlines and writing captions to pictures. Yet, as R J Purdey’s play - which was a sellout hit at this venue last year and now returns for another run - makes clear, there is some comic juice to be squeezed out of the dreams and tribulations of these worker ants.

Incongruence is always interesting, so the news earlier this year that Anthony Neilson, bad-boy author of adult plays such as Penetrator, The Censor and The Wonderful World of Dissocia, was penning a Christmas play — suitable for kids — at the Royal Court came as something of a delightful surprise. It was also clearly a chance to make amends for The Lying Kind, his 2002 seasonal venture at this address, which received what are politely called mixed reviews. This time, it's good to be able to report that his new festive comedy, which opened last night amid gales of laughter, proves that he has returned to top form.

Middle-class family angst continues to be this season’s theme at the Royal Court Theatre, but this time it is seen through the eyes of 10-year-old girls at a 1990s boarding school. But don’t expect this to be an episode of Malory Towers or even the rather good-natured naughtiness of St Trinian’s. No, this is a bleak institution where the girls are foulmouthed and vicious in their rivalry. As Mrs B, who supervises the dorms, says to the headmistress: “They are small dogs doing what small dogs do.”

London’s world-famous experimental pub-theatre has secured its future with a move into Shepherd’s Bush old library. Church and council permission were given yesterday for conversion of the library (owned by the Church of England) to be ready for curtain-up in 2011 when the lease on the Bush’s space in O’Neill’s pub, Shepherd’s Bush Green, expires.

Few playwrights have been so successful at moulding our view of a nation as Athol Fugard. It’s impossible to think of South Africa, especially during the apartheid years, without thinking of his Sizwe Bansi is Dead, The Island or Statements after an Arrest under the Immorality Act. Since the end of the old regime in 1994, the moral fuel that powered his plays may have evaporated, but this new work, one of nine premiered by the 78-year-old author in the past 15 years, shows that his feeling for stagecraft and his concern for human dignity remain undiminished.

If any play of the past two decades deserves the label legendary it must be Sarah Kane’s debut, which was condemned as “this disgusting feast of filth” on its arrival in 1995, but is now firmly ensconced in the canon of contemporary playwriting. Although the shock of its original production, which in retrospect simply heralded the appearance of a distinctive new voice, has led audiences to expect a similarly frightful experience every time it is revived, subsequent productions have emphasised the play’s poetry and its relevance.

Let's face it, the rom-com has an image problem. Too often, this genre is tainted by either sugar-sweet sentimentality or crashing cliché, or both. Often, there’s something more than a little oppressive about the whole idea of romance, as if love’s natural idealism is too weak to withstand a cold dose of reality. But there are exceptions. And this show is one of them. It’s great to be able to welcome D C Jackson’s new play, which he calls a “non-rom-com”, and which arrives in London having first enjoyed a successful outing at the Edinburgh Festival in August.

Verbatim drama, long established in theatre, has rarely been used in film. But director Clio Barnard uses the device to magnificent, and sometimes deliberately disjointing, effect in The Arbor, to tell the story of Bradford playwright Andrea Dunbar, who wrote The Arbor and Rita, Sue and Bob Too (made into a film in 1986) before she died at the age of 29 in 1990.

When, earlier this year, Edward Hall took the reins at the Hampstead Theatre, some eyebrows were raised. It’s meant to be a new-writing theatre and Hall has had much more experience directing Shakespeare than in tackling new plays. On the other hand, this venue needed a clean sweep and Hall is certainly able to wield a new broom vigorously. His first show, Shelagh Stephenson’s thrilling play about the disappearance of a gap-year student, opened last night — and it’s an excellent debut.
