The original TV-version ran two nights for a total of four hours (198 minutes minus the commercials). Most video copies are pared down in length, one running 122 minutes and another "expanded" to 132 minutes. Both these versions are missing key scenes such as:
- The introduction of of the alternate personality "Vanessa"
- Sybil's first date with Richard
- Her recollection of her childhood sweetheart.
- Sybil dissociating into the personality of an infant, leading to Dr. Wilbur's memorable statements "My god Sybil, what did that monster do to you? What happened in the green kitchen?"
- Dr. Wilbur confronting Willard Dorsett over him having left his daughter in the care of such an obvious and dangerously disturbed woman as Hattie
- Sybil's two male personalities arguing with Dr. Wilbur about them being able to father children
- Sybil finally confronting and learning to accept all of her personalities while under hypnosis
