Dr. Jekyll (Ralph Bates) is a scientist researching the cure of many diseases. He is a very reserved and shy man, and spends most of his time working on his laboratory. One day, his friend Professor Robertson (Gerald Sim) visits him and advises that he would probably die before the conclusion of his studies. Dr. Jekyll decides to research an elixir of life, based on feminine hormones, to extend his life and consequently end his work. He uses female corpses to get the hormones. The effect of the elixir releases his '"feminine repressed side" and he becomes an aggressive and beautiful woman, Ms. Hyde (Martine Beswick). When the bodies finish in the city morgue, Dr. Jekyll starts killing women to proceed with his research.
"Dr. Jekyll & Sister Hyde" is another charming movie by Hammer and a great entertainment. The theatrical style uses few locations and the gore and killing are not graphic. Fans of Hammer Film Productions will certainly enjoy this different version of the classic story Dr. Jekyll and Mr. Hyde. My vote is seven.
Title (Brazil): "O Médico & Irmã Monstro" ("The Doctor and Sister Monster")
