Sugary sweet Loretta Young does an uncharacteristic about-face in 20th Century Productions Born to be Bad. Young is cast as Letty Strong, an unwed teenaged mother who tricks happily married dairy farmer Malcolm Traver (Cary Grant) into adopting her baby. She later uses all her feminine wiles to steal Traver away from his mousy little wife Alyce (Marion Burns). Bad though Letty is, however, shes still portrayed by Loretta Young, so a last-minute redemption is inevitable. Juvenile radio actor Jackie Kelk plays Lettys obnoxious child, who (somewhat amusingly) turns out to be a bastard in more ways than one. No relation to the 1950 Joan Fontaine vehicle of the same name, Born to be Bad was co-scripted by actor Ralph Graves. ~ Hal Erickson, All Movie Guide
