The voice of "Aaron" is provided by Gordon Anderson, who was Sondra Locke's husband at the time, although it was later sensationally revealed that their 51-year marriage had never been consummated.
Despite playing mother and daughter, Mary Ure is only 11 years older than Sondra Locke, who was almost twice her character's age.
