Jean Simmons' fascinating interpretation of an uncharacteristic role is the main drawing card of Otto Preminger's Angel Face. The daughter of Charles Treymayne (Herbert Marshall), who remarried a wealthy woman (Barbara O'Neil), Diane Treymayne's (Simmons) angelic countenance masks an unbridled psychotic who'll let nothing stand in the way of her happiness. Diane arranges for Catherine's death, making it look like an auto accident. Coveting family chauffeur Frank Jessup (Robert Mitchum), Diane steals Frank away from his sweetheart Mary (Mona Freeman) and forces him to become her spiritual accomplice in her stepmother's murder. And when Diane finally realizes that she'll never, ever, be able to hold Frank, she... well, enough said. If Angel Face doesn't look like a typical early-1950s RKO Radio film, it may be because its director was borrowed from 20th Century-Fox, and its cinematographer (Harry Stradling) was a loan-out from Sam Goldwyn.
