Claim: In the plot of The Three Faces of Eve, a mother with severe headaches and blackouts learns she has multiple personalities.
Evidence: In 1951, Eve White is a timid, self-effacing wife and mother who has severe and blinding headaches and occasional blackouts. Eventually goes to see psychiatrist Dr. Luther, and while having a conversation, a "new personality", the wild, fun-loving Eve Black, emerges. Under hypnosis at one session, a third personality emerges, the relatively stable Jane.
