In Vidor’s adaptation of Olive Higgins Prouty’s 1923 novel, Barbara Stanwyck created one of the most indelible heroines of Hollywood’s Golden Age: a rough-around-the-edges millworker’s daughter who, even after she schemes her way up a peg on the social ladder, can’t quite shake her working-class ways as she does whatever it takes to give her daughter (Anne Shirley) a better life. This is 200-proof melodrama in its purest form, ruthlessly wringing pathos from its nerve-touching themes of class, motherhood, and self-sacrifice. Through it all, Stanwyck is a miracle, pouring every ounce of Brooklyn brass and just-below-the-surface vulnerability she’s got into the endearingly crude Stella, before going in for the kill with the titanic heartbreak of the impossible-to-forget ending.
