When Joint Stock began their latest project four months ago, they had a writer but no script, actors but no roles. 'Borderline', by award-winning young playwright Hanif Kureishi, finally emerged out of the remarkable working process unique to the Joint Stock Company. Kureishi wanted to write a play about the problems faced by the Asian community in Britain, and his final script was the result of research, workshops and improvisation involving the whole company - writer, director and actors.
