Claudio Carvalho 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")

TheLittleSongbird Hammer Films produced a number of classics and an even larger number of very good, entertaining films and a few misses. While Dr Jekyll and Sister Hyde is not a classic, it is one of their better later films, and much better than Hammer's other Jekyll and Hyde re-imagining The Two Faces of Dr Jekyll.Dr Jekyll and Sister Hyde looks incredibly good, no surprise seeing as Hammer's films always looked good no matter the quality of the rest of the film. The sets and lighting recreate the Victorian London era with lovingly and evocatively and they look sumptuous and splendidly Gothic. One also has to love the rich colours and the beautiful and atmospheric photography. It is not just that the production values look great that is really well done, but also how much it contributes towards the feel and atmosphere of the film, here the atmosphere is wonderfully moody and has a real sense of fear throughout, which were not always there as effectively in other later Hammer films.The film also has a chillingly haunting, with also some touches of lush romanticism, score with an at times Rachmaninov sound to it, the dark richness of the orchestration adding so much. It also has the advantage of being well placed and used effectively, excepting some overblown moments in a couple of the transformation scenes. Dr Jekyll and Sister Hyde is very intelligently scripted, with some witty and thought-provoking dialogue, while the story(with one of Hammer's most innovative and pretty ingenious premises) is incredibly clever and enormous fun, the suspenseful and often very creepy atmosphere staying consistent all the time and the chills and scares come off tastefully and unsettlingly. Loved the use of the Jack the Ripper mystery, which really did give off a sense of dread, and the nod to Sweeney Todd. The transformation scenes are beautifully shot and boast good effects work and a real edge-of-your-seat tension. The film is strongly directed, the characters carry the narrative very well and the acting is solid; with Ralph Bates giving by far his best performance in a Hammer film and Martine Beswick- youthful beauty at its best- even better in a menacing but never over-the-top performance.It's not perfect however, but comes close. There are a few pacing longueurs, where a few scenes towards the start dragged just a little. And while the film is incredibly entertaining, rich in atmosphere and does a great job with the majority of its ideas, others did come off rather clumsily, especially the anachronistic and out of place inclusion of Burke and Hare, leaving one wonder why they were included in the first place(a nod to Stevenson's story The Body Snatcher perhaps?).Overall, while not without flaws and not one of the Hammer classics, it's one of their better later films and never fails to entertain, chill and engage, making the most out of a great premise. 8/10 Bethany Cox

Michael_Elliott Dr. Jekyll & Sister Hyde (1971) ** 1/2 (out of 4) Hammer's gender blending version of the Stevenson novel has Henry Jekyll (Ralph Bates) experimenting with extending life but he accidentally turns himself into the beautiful but deadly Mrs. Hyde (Martine Beswick). This here is certainly an ambitious little film that works a lot better than it should have. I think the biggest key is the screenplay by Brian Clemens, which throws everything into the picture and just hopes it sticks. Not only do we get the gender bending version of Jekyll and Hyde but we also get Jack the Ripper elements thrown in and we also get Burke and Hare elements added for good measure. We've basically got three different movies going on here and it's all held together with some very good direction by Baker. He handles the material quite well and mixes it up nicely and for the most part delivers a good film. The biggest problem is that the movie starts to run out of steam towards the end and the final ten-minutes are pretty dragging. Another strong aspect are the performances by Bates and Beswick. It's remarkable how much they look alike and this adds to the story of them being brother and sister. Both are very strong in their roles with Bates really shining and I'd say he's one of the better Jekyll's out of any of the versions. Susan Broderick is also very good as the neighbor who loves Jekyll. I think this film is a lot better than Hammer's previous attempts at Jack the Ripper or the Jekyll/Hyde tale and the added sexuality makes this one to watch.

rose-294 Hyde as a woman! Could be a bad comedy, but thankfully it is not. Made as a Gothic thriller with some humor in it, Brian Clemens'script is nothing short of a masterpiece. Sister Hyde/Jill the ripper in her strikingly scarlet and feminine dresses is sexy and blood-thirsty without filthy ho-look and her stalking scenes in the streets of 1888 London, accompanied by David Whitaker's wonderful score, make this lady one of the great villains of cinema. No, not just horror movies but cinema in general. Photography and sets are good - hey, this is a Hammer film! - and Susan Brodrick's rose-coloured jacket-dress ... lovely! Burke and Hare, who sold the bodies of their victims to the doctors in 1820s Edinburgh, are now magically transported to another time and place, with a bit of 1950s British movie Flesh and the fiends (the duo's fate in the hands of the mob) thrown in for the good measure. There's even mention of the legendary Victorian killer barber Sweeney Todd and the fate of HIS victims in Burke's comment "If I were you, I would not eat meat pies in this neighborhood". Alternative universe Hammer, so don't whine about lack of realism.
