When artistic director Dominic Cooke took up his new post at this venue in 2007, he said that he wanted “to look at what it means to be middle class, what it means to have power, what it means to have wealth”. Although this comment caused a lot of fuss, with die-hard Royal Court fans imagining that he was about to betray the theatre’s tradition of staging plays about low-lifes, Cooke’s programming has managed to balance gritty underclass dramas with plays about the rich and privileged.

It's common to feel a real sense of doom when you approach the Elephant and Castle Shopping Centre. But it’s not the dodgy hoodies that turn your legs to jelly, it’s the sheer ugliness of the architecture. Yes, aesthetically, this is urban hell. But it’s also the site of the Royal Court’s Local project, in which a rundown shop unit has been turned into a makeshift theatre. Random, a spirited revival of Debbie Tucker Green’s 2008 play, is the first of a season of edgy dramas to make the trek from Sloane Square to Southwark.

Over the past decade, much of the energy in new writing has come from black Britons. Homegrown talents such as Roy Williams, debbie tucker green and Kwame Kwei-Armah have sent us updates about the state of hybrid, streetsmart culture, and alerted us to the experiences of minorities. In doing so, they have reinvented punchy dialogue, with stage chat that zips along with dizzy humour and linguistic freshness. Hot on their heels comes Bola Agbaje, whose latest play has just opened on the main stage at the Royal Court.

Looking at posters outside the Apollo Theatre, where the West End transfer of Jez Butterworth’s award-heavy Royal Court success opened last night, you might be tempted to start humming: “And did those feet in ancient time…” But such nostalgic sentiments are unlikely to survive the opening scene of this phenomenal play. Soon after the curtain, a symbolically faded flag of St George, rises, we see a familiar rural scene: under-aged kids stoned out of their minds, dancing in a thumping rave. It’s a nocturnal bacchanalia of house music, gyrating girls and drug-addled wildness.

Crisis makes people hungry. In the case of the banking collapse, this seems to take the form of an ignoble itch for revenge, and a more laudable hunger for knowledge. What exactly happened and what went wrong? As Enron, Lucy Prebble's wonderful play about a previous financial scandal, roared into the Royal Court after its sell-out run at Chichester, there was time to reflect on just why this play has been such a huge success. And by success, I really mean success.

Reviving rarely performed plays is a high-risk strategy. On the one hand, there’s the chance of discovering a forgotten gem; on the other, there may be good reasons for the play being rarely performed. Nigel Dennis’s The Making of Moo was first staged at the Royal Court in 1957 with a cast that included Joan Plowright, John Osborne and George Devine, and provoked accusations of blasphemy. How has this satire on religion stood the test of time?

Richard Bean's monster mainstage play, England People Very Nice, was about immigration to London's East End - and was easily the most controversial play of 2009. He is a son of Hull (b. 1956). He is one of the most prolific and talented playwrights to emerge on the British new writing scene since the start of the new millennium.
