"A cleverly woven design of warped psychology and phantom jealousy is excellently directed by Jacques Tourneur in his best terror evoking mood. Hedy Lamarr plays the wife of a sadistic millionaire who attempts to drive her mad. This archetypal plot with overtones from Gaslight, Jane Eyre, Rebecca and many other Victorian-type melodramas, is especially notable for the way the flashbacks are used to unsettle the viewer at the beginning so he is forced into the film's uncanny mood." --British Film Institute
