Movies like Priscilla and the Umbrella

Paul and Harry certainly have a tempestuous time fighting for the good graces of Priscilla. Paul is such a "boob" that she is forced to rid herself of him and by a clever subterfuge bring Harry to her feet, at the same time finding out how sincerely his affections are towards her. The subtle part of it is that she makes Paul the unconscious instrument of her cunning and he himself was his own executioner.
