In August this year, the East West Theatre Company from Sarajevo brought a new version of Nigel Williams' play Class Enemy to the Edinburgh International Festival. It's a hard-hitting and foul-mouthed production that tackles the topical subject of youth violence head-on. Is Edinburgh ready for such an unstintingly brutal portrait of the lives of young people today? The programme meets the cast and director Haris Pasovic at home in Sarajevo and follows the journey of the play to Edinburgh and then on to the Glasgow suburb of Rutherglen to see how the production goes down with a group of Scottish teenagers.
