Trivia / Doctor Jekyll and Sister Hyde

• Hostility on the Set: Martine Beswick has said that her topless scenes were originally intended to feature full-frontal nudity, but she fell out with director Roy Ward Baker over how much she wanted to show, and they did not speak to one another for a week.
• Romance on the Set: Husband and wife Ralph Bates and Virginia Wetherell first met as they prepared to shoot the scene in which Bates as Dr. Jekyll kills the prostitute played by Wetherell.
• What Could Have Been: Caroline Munro and Kate O'Mara both refused the lead role(s) because of the nudity required.
