The screenwriter for "The White Sister," Donald Ogden Stewart, has an uncredited bit playing the hind end of a horse; that pretty well sums up this picture. It's an insipid, implausible, and uncompelling film that wastes a lot of prime MGM talent. <br /><br />***SPOILER ALERT*** The story concerns the ill-fated love between a sheltered, aristocratic Italian girl, Angela Chiaromonte, and a dashing soldier, Giovanni Severi. He pursues her despite the strenuous objections of her father and thwarts her marriage to a wealthy bankeran alliance that apparently was meant to save the girl's family from financial ruin. Their romance leads indirectly to the death of Angela's father in a car crash. The affair goes downhill from there. Throughout the film, Angela and Giovanni keep getting together only to be torn apartfirst by her father, then by the war, and then by God himself. Their rotten luck and bad timing are almost comical. Sent off to battle, Giovanni implausibly survives a horrific plane crash, then makes a daring escape from a German prisoner-of-war camp, only to find that Angela, believing him dead, has become a nun. At this point, there's nothing left for him to do but die an anticlimactic death with his white-habited fiancée at his bedside.<br /><br />The two leads, Helen Hayes (Angela) and Clark Gable (Giovanni), give it their best, but they can't overcome being both miscast and mismatched. Coming into his own just as films learned to talk, Gable exemplified the "new" American male: confident, brash, and openly sexual. The old-fashioned pieties of this movie fit him like a straight jacket. Hayes is more plausible in the role of the spirited/spiritual young girl. While you can see how she'd be carried away by Gable's charisma and animal magnetism, it's hard to understand why he'd be so attracted to this mousy little innocent. The whole enterprise might just have worked with someone like Leslie Howard as Giovanni; his restrained classical style would have been better suited to this dated material. <br /><br />Other welcome and familiar faces include Edward Arnold as a sympathetic priest (like Gable, though, he's seen to better advantage in earthy or roguish parts); Louise Closser Hale as Angela's duenna/companion, and May Robson as the Mother Superior. Uncredited but recognizable are Gino Corrado as a chauffeur, Nat Pendleton as Giovanni's soldier buddy, and Greta Meyer as the Italian-German woman who nurses Giovanni back to health after his plane crash.<br /><br />A minor quibble, but I found it hugely annoyingnone of the characters can agree on how to pronounce "Giovanni." Hayes, as Angela, seems to say it differently (and wrong) every time, which is odd considering her character is supposed to be madly in love with him.<br /><br />Worth watching mainly as an opportunity to catch Helen Hayes in one of her infrequent film roles (her reputation was primarily as a stage actress) and for Gable's characteristically charming performance (not to mention beefcake appeal!) in an uncharacteristic role.
