Close-up: Tarell Alvin McCraney

With three new plays, the 27-year-old aims to change the face of theatreland

Exploring Yoruban cosmology, trawling through New York drag clubs and rebuilding the spirit of New Orleans post-Katrina – Tarell Alvin McCraney's life is nothing if not varied.

The 27-year-old actor-playwright from Miami made his London debut last year, and is back this autumn at the Young Vic with the same play, The Brothers Size, as well as a second in his "Brother/Sister" trilogy, In the Red and Brown Water, before taking a third to the Royal Court Theatre.

While the first of these plays is a sparse, intense fraternal drama drawing on hip-hop rhythms and west African mythology, the second is a coming-of-age story, and the third... well, the third will transform the Royal Court into a drag queen's boudoir as its Christmas show, Wig Out!, McCraney's exploration of gender-bending, which also opened in New York last week.

McCraney is a disciple of the British innovator Peter Brook, and shares his belief in the sanctity of theatre: "People are sitting together in a room, believing together in something they can't see. How many times are we in a situation when everybody's imaginations and beliefs are invited?"

That's another of McCraney's passions: ensuring those usually excluded by theatre are represented. Last year, he went to New Orleans to stage a play about Hurricane Katrina. And last week, he was haunting Manhattan's drag clubs at 3am, giving out Wig Out! flyers. "Not because I want these people's money, but because I want them to see this show. Without young people, without people of colour, without those who feel their voice doesn't belong, American theatre will lose all its richness."
