The multiple award-winning made-for-TV movie Sybil was based on the book by Flora Rheta Schreiber. Sally Field won an Emmy for her portrayal of the title character, a substitute teacher in New York who has developed multiple personality disorder. As a coping mechanism to deal with the abuse she suffered at the hands of her mother, Hattie (Martine Bartlett), Sybil created separate personalities: aggressive Peggy Lou, suicidal Mary, baby Sybil Ann, and several others. Joanne Woodward plays Dr. Cornelia Wilbur, the psychologist who diagnoses Sybil's condition and helps her to get over it. William Prince and Jane Hoffman play her father and stepmother, while Brad Davis appears as her would-be boyfriend Richard. Originally shown in 1976 as a two-part special on NBC for a total of almost four hours, but most home video versions have been edited down to two hours.
