Who Is Julia? was based on author Barbara H. Harris' "speculative fiction" page-turner. Mary Frances (Mare Winningham) is a dull, drab housewife suffering from brain disease. Julia (Judy Ledford) is a drop-dead-gorgeous model who is killed in a car accident. Out of desperation, the surgeons decide to transplant Julia's brain into Mary Beth's body. The balance of the film involves Julia's distressed reaction to being trapped with the plain features and blue-collar lifestyle of Mary Beth. Sidelines sufferers include Jameson Parker as Julia's husband and Jonathan Banks as Mary Frances' spouse. Who Is Julia? is a farfetched but irresistible made-for-TV effort.
