The Simian Line (2000)

In addition to declaring that Katharine's (Lynn Redgrave) head and heart line are hopelessly fused into one "simian line", eccentric palm reader/fortune-teller Arnita (Tyne Daly) makes a dire prediction: By the end of the year, one of the couples present at a Halloween party will have broken up. But will it be Katharine and her much-younger boyfriend Rick (Harry Connick Jr.); her upstairs tenants Marta and Billy or new yuppie neighbors Sandra (Cindy Crawford) and Paul? Fueled by Arnita's prediction, each of the couples begins to drift apart in a sea of doubt and distrust. Can the "divine" intervention of two well-meaning ghosts (William Hurt and Samantha Mathis) keep these earthly conflicts from erupting into multiple self-fulfilling prophecies?—Anonymous
