Caryl Churchill, hailed by Tony -Kushner as "the greatest living English language playwright," has turned her extraordinary dramatic gifts to the subject of human cloning-how might a man feel to discover that he is only one in a number of identical copies. And which one of him is the original. . . ? A Number opens in London's Royal Court Theatre in October, directed by Stephen Daldry (Billy Elliot).

Caryl Churchill is the author of some twenty plays including Cloud Nine, Top Girls, The Skriker, Blue Heart and Far Away.
