The last time I saw Janet McTeer, she was doing her best with the slightly underwritten role of sister to Glenn Close’s lethal Patty Hewes in Damages, the ultimate TV series about the discrepancy between seeming and being. Which is the theme, too, of Christopher Hampton’s Les Liaisons Dangereuses, adapted from Choderlos de Laclos’ peerless epistolary novel.

On contemporary stages, absence is a constant presence. This is very odd if you consider how corporeal and concrete theatre is. Unlike film, which is just light shining on a screen, or books, which are just letters on the page, theatre is live performance that is irreducibly there in the same space as you are, breathing the same air. Yet many playwrights – led of course by Samuel Beckett, Caryl Churchill and Martin Crimp – have explored the notion of absence on stage.

From Singin’ in the Rain and Anything Goes to Hello, Dolly! and Mary Poppins, Olivier Award winner Stephen Mear has done more than any other British choreographer to usher classic musicals into the modern era. But adept as he is at razzle-dazzling ’em, there’s more to Mear, as recent excursions like City of Angels at Donmar Warehouse and Die Fledermaus for the Metropolitan Opera prove.

Political sleaze, arguments over Europe and fears for the NHS – sometimes it feels as if it’s the 1990s all over again. And, right on cue, theatre has been staging a whole shelfload of revivals of work from that decade: Kevin Elyot’s My Night with Reg, Conor McPherson’s The Weir and Jonathan Harvey’s Beautiful Thing. The Donmar Warehouse, under the spirited leadership of Josie Rourke, has led this trend, and its latest offering is Closer, Patrick Marber’s brilliant 1997 play, revived now with Rufus Sewell in the cast.

Drop-dead dames, a hard-bitten gumshoe, an ambitious writer and a sleazy movie mogul: this slick, sassy 1989 musical by Cy Coleman, David Zippel and Larry Gelbart serves up two parallel tales of Forties Tinseltown – and both of them are swell. Directing her first musical, Josie Rourke tackles this dazzling collision of noir thriller fantasy and garish Hollywood machinations with seductive brio. And her cast glide between the show’s twin dimensions with an elegance and wit worthy of stars of the classic silver screen.

It’s hard to believe that almost two years have passed since Phyllida Lloyd’s Julius Caesar at the Donmar Warehouse. Harriet Walter’s stricken face as the play ended is still burningly fresh in the memory as we return to the theatre for Henry IV – Part II of a planned trilogy of all-female Shakespeare plays. Incarcerating us once again in a women’s prison, can the power of Lloyd’s conceit survive a second outing?

Daniel loves Reg; so does John. Guy loves John; John doesn’t love Guy. Bernie loves Benny, and drives him mad. And as for Eric, he once thought he could fall for Reg – but they only shared one night together, and he never even knew Reg’s name. And anyway, as he points out, unlike the middle-aged others, he’s young – “I’ve got plenty of time.”

Brian Friel’s affinity with Russian writers, notably Chekhov and Turgenev, is central to his work, the playwright seeing similarities between their tragi-comic characters, hanging onto “old certainties” despite knowing in their hearts that their time is up, and people of his own generation in Ireland. The correspondences go beyond theme, of course; he’s not known as the Irish Chekhov for nothing.

The transfer this week to the West End of The Weir has reminded theatre-goers of Conor McPherson’s hypnotic powers as a dramatist. In the Donmar's revival of the play you can palpably feel the playwright’s storytelling magic casting its spell all over again as, on a windy evening in a rural Irish pub, character after character unburdens himself - and finally herself - of a supernatural tale.

In his later life Shakespeare, who never ducked ways to define a hero, offered the public a challenge: Coriolanus is a professional warrior, deaf to reason, patrician hater of people power. To beat all, this man’s man’s a mother’s boy. In a world trying to be newborn in democracy and a big society, Coriolanus sticks out like a sore thumb.
