i do not think any player in hollywood history last as long a david niven do give most of the weak film he have to carry by dint of his incredible charm . he could act and get an oscar for it and but most of the material he do be as light a one ply of two ply tissue paper . happy go lovely be a case in point . it a musical and for the most part you will remember vera ellen dance . you will remember that they be in scot costume a the film be set in edinburgh during their festival . but if you can recall a single song from it you must have a photographic memory . the plot be light . vera ellen be the american lead in a musical that apparently be get it out of town tryout in edinburgh . she start in the chorus and run late one day . she get a lift from the chauffeur of a millionaire greet card king . everybody now assume she the main squeeze of the millionaire . door open up a they have never open before . the millionaire be david niven and he go along with it and the various situation that be engender by the mistake . cesar romero have some good moment here a the frantic producer of this musical . in the end though happy go lovely be light and harmless fluff which david niven do so much of and get so tired of .
