Matthew Sweet talks to political playwright David Edgar about Testing the Echo, his new play about a group of immigrants preparing to take the new British citizenship exam. Does he believe that immigration and citizenship should be top of the country's agenda? Plus a review of the latest film from Danish maverick director Lars Von Trier, famous for starting the Dogma movement, whose work now seems to have taken another new turn with The Boss of It All, a comedy about an IT firm.
