i love the thackeray novel on which this film be base . and while this modern version of becky sharp story be a b film and the casting of loy and in her first top bill role and be rather fascinating . before loy become mgm reign good girl in score of genteel and comic role and she be an actress . vanity fair be loy follow up film to emma and in which she play a snotty and greedy daughter who almost destroy the loyal housekeeper ( marie dressler ) . loy becky be much nasty than miriam hopkins version 3 year later in becky sharp . loy becky be very much a pre code film character with her plunging neckline and amoral way . it the type of character that jean harlow or clara bow could easily have play and but becky here be still suppose to be of the genteel set . that what make her fallen character so tragic . in counterpoint to loy grasp becky be the goody goody amelia ( barbara kent ) who be just not an interesting character . mary forbes be icily good a mrs. sedley . most of the other actor in this version be pretty blah represent conway tearle a rawdon while walter byron a osborne while anthony bushell a dobbin . others be nearly dickensian be their quirkiness represent billy bevan a joseph while lionel belmore a crawley while montagu love a the marquis while lilyan irene a polly the maid while elspeth dudgeon a the housekeeper . loy be front and center throughout . while the end be rather shock and she have several excellent scene and such a the gamble scene in the casino where she try to steal another woman win roulette bet . the more loy becky descends morally and the more beautiful she get until she be finally catch . bottom line here be that this be a very solid performance by loy in a film that should be see .
