Joanne Woodward and Lee J. Cobb star in this 1957 movie, one of the first to dramatize a case of multiple personality disorder. Cobb plays the therapist who discovers that his patient, played by Woodward, appears to have three very distinct personalities. A generation later, in 1976, Woodward played the psychiatrist treating a female patient with an even larger and more disparate array of personalities. That was in the 1976 NBC miniseries Sybil, starring Sally Field as the patient.
