Single White Female (1992)

Synopsis
In this psychological thriller, a needy young woman finds fulfillment by trying to literally become her successful roommate. Attractive Manhattanite Allison Jones (Bridget Fonda) has it all: a handsome beau, a rent-controlled apartment, and a promising career as a fashion designer. When boyfriend Sam (Steven Weber) proves unfaithful, Allison strikes out on her own but must use the classifieds to seek out a roommate in order to keep her spacious digs. In steps Hedra Carlson (Jennifer Jason Leigh), who's timid and frumpy but puppy-dog sweet. The self-centered Allison finds Hedra's eager friendship flattering, but soon she grows annoyed as Hedra begins emulating everything about her. After Allison gets back with Sam and asks Hedra to please vacate the premises, the pert beauty really gets to see her weird new roomie's bad side -- Hedra, it seems, is downright homicidal. Directed by Barbet Schroeder, who wowed Hollywood with Barfly and Reversal of Fortune. Single White Female was the second screenplay from future Opposite of Sex director Don Roos. ~ Brian J.
