Madame X is a 1966 American suspense drama film directed by David Lowell Rich and starring Lana Turner, John Forsythe, Ricardo Montalbán, Burgess Meredith, Constance Bennett, and Keir Dullea. Based on the 1908 play of the same name by French playwright Alexandre Bisson, it follows Holly Anderson, the wife of a wealthy American diplomat who, under the pressure of her mother-in-law, fakes her death after the demise of her lover. Holly spends the following fifteen years abroad under a false identity before becoming embroiled in a legal battle after she commits a murder, during which she is unknowingly represented by the son—now a successful attorney—whom she was forced to abandon.
