A sleeper cell sets off a bomb on a London Double Decker bus, eh? Maybe our current worries aren’t so unique? Sylvia Sidney is the lovely young manager of a cinema, involved in some odd marriage deal with a foreign sounding (terrorist!) husband. Will the neighboring greengrocer/Scotland Yard plant provide her with love AND prevent little Timmy from inadvertently setting off that bomb in Picadilly? At 80-something minutes, there’s nothing here that isn’t clever, captivating and edge-of-your-seat. Plus, very British.
