This filmed adaptation of the National Theatre's 2011 musical ‘London Road’ invites a fresh look at old truths about prejudice, suspicion and, finally, solidarity. The weird brew that director Norris and co have cooked up is giddily intoxicating: the songs rubbing up against the subject matter, the actors repeating words spoken in interviews to the show’s writer, Alecky Blythe, giving them a heightened, ‘reported’ feel. There are choreographed dances in dismal suburban locations, and a careful casting of faces that are at once ordinary and extraordinary.
