Played By: Rita Hayworth
Movie: Gilda (1946)

The eponymous cabaret singer is simultaneously the object of every man's love as well as their contempt, rarely resembling anything close to faithful during her two dysfunctional relationships in the film. She first surfaces as the brand new trophy wife to casino owner Ballin Mundson (played by George Macready), but all she's really concerned with is driving her former lover, and Mundson's right hand, Johnny (Glenn Ford) wild with jealousy—with other men.

When Mundson disappears, she and Johnny consummate their sexual tension and marry...only to devolve right back into the hate side of their love/hate dynamic, leading her to stripteasing for other men to send him up the wall again. Whatever helps to spice up the relationship.
