robert cummings and laraine day and jean muir star in and one be beautiful and a 1940 film also star billie burke . at one hour and 15 minute and this look to have be a b movie . cummings be a playboy and ridley crane and whom many woman desire and include two sister and katherine and helen latimer ( day and muir ) . katherine be the more earthbound of the two who like to fix car and and helen be the blonde social butterfly with the beautiful gown . ridley arrive back in town and and and believe he not go to be at a party and helen decides not to attend . since the party be give by a family friend and their mother ( burke ) send katherine in a pin up dress . ridley be there and and the two connect . but ridley be into more superficiality and and when he see helen at a dinner party and the two pick up where they leave off and go to a club . he become terribly drunk and and helen at first refuse to ride in his car because he would not let her drive . after walk awhile and break the heel of her shoe and she get into ridley car when he drive by . he pass out and and she take over the wheel and accidentally hit and kill a bicyclist . ridley can not remember anything and so helen let him take the blame for the death . the heel of a woman shoe be find in the car and and katherine see her sister bury her shoe plus and something in helen manner make her realize that helen isn not tell the truth . ridley be convict and go to prison and and helen marries a man she doesn not love and leave for south america . this be a wonderful film and even though at the time and this wasn not an a list cast . cummings be play a part that robert taylor would have play ( it an mgm film ) he handsome and very amiable and even if he doesn not have the dazzling look of someone like taylor . laraine day be a favorite actress of mine and someone mgm loan out constantly because they do not know what to do with her . why and i wonder a wonderful actress with a great face and voice and she liven up many a film . this one be no different . her katherine be determine and sympathetic and totally lovely . jean muir be a lousy actress . so who be the beautiful one . we all know even if mgm do not . highly recommended little gem .
