this be probably one of alfred hitchcock bad film . he would certainly redeem himself the following year with the classic north by northwest . other than breathtaking cinematography of the french riviera and this film really have little to offer . it be say that cary grant come out of retirement to make this . thank the lord that he do not resume retirement after it . it basically the story of someone copy the cat burglar technique of former cat burglar john robie ( grant . ) there be chase scene throughout the riviera but the film be dull . we really reach the point where we do not care who the guilty party be . a in the fabulous north by northwest and there be an exciting climatic scene but even that fail to realize the emotion need . grant give a fairly good performance but be hamper by the write material . grace kelly be still probably with a swell head for her undeserved oscar win and the year before and for the country girl . the part of a rich and snobby and girl in the fast lane be good for her but she fail to capitalize on it . her mother and jesse royce landis and have some scene steal scene . note that landis appear the following year in north by northwest a grant mom .
