Dr Jekyll has to deal with gender confusion
Dr Jekyll and Sister Hyde was a Hammer Production. The twist was that they took the Dr. Jekyll story and added Jack The Ripper and gender transformation. Jekyll played by Ralph Bates is obsessed with transforming himself into a woman and must kill females to get the right ingredients. There was some sex mixed in on the top as well. Eventually the good doctor is fighting over what gender he wants to be. It’s a pretty good plot executed well as are most of the films made by Hammer. Martine Beswick from James Bond fame plays Sister Hyde and she’s a site to see.
