Organnall Too much about the plot just didn't add up, the writing was bad, some of the scenes were cringey and awkward,

Aubrey Hackett While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

Roy Hart If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.

Staci Frederick Blistering performances.

rodrig58 The film is not great, despite the efforts. As acting performances, the best are Gerald Sim and Susan Brodrick. Ralph Bates is repeating himself and is not a right choice, not creepy enough, not convincing at all. The same can not be said about Martine Beswick, for her is perhaps her best role. Nice ass and breasts too! Roy Ward Baker is a good director but with other films, especially "The Saint"(TV Series), "The Avengers"(TV Series), "The Baron"(TV Series).

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")

trashgang This Hammer flick was a major turn in the career of Martine Beswick. Her first flick could have been a major role in Dr. No but the director preferred Ursula Andress instead but promised her another role in another James Bond which became From Russia With Love. After Jams Bond she appeared in a lot of flicks but had one problem, she didn't want to do nudity. Even as she was asked to do it she refused in way that her career was influenced by it. But to cut a long story short, she was asked by Hammer to have a lead in this flick, an era were Hammer had a lot of nudity in their flicks and so she agreed to appear naked. Only her breasts should be shown but due a game of the director he asked her to go full monty and somehow the studio was full of people watching her strip. She wasn't offended by going nude and after the Hammer flicks she went into Italian soft core flicks. Once that she was done with that she went to television for series and commercials. So here we have her for the first time in her nudies. Luckily for the Europeans it came in an uncut edition, sadly for the US the nudity was cut out to have a commercial rating. The flick itself hasn't really a typical Hammer Gothic feeling but it still works. It's based on the Jekyll and Hyde story combined with the Jack The Ripper story. The filming is sublime and the acting is really good. Of course there is blood in it but you never see the knife going in, the effects are up to today's standard laughable, especially the transformation from Jekyll to Hyde. Nevertheless, it's enjoyable and surely one to watch and to have in horror collection.

Witchfinder General 666 Hammer's take on the Robert Lewis Stevenson's unforgettable novel is an amazing one indeed! Personally, I think that the great Hammer Studios produced some of their greatest films in the early 70s, and "Dr. Jeckyll and Sister Hyde" (1972) is a great one indeed. Directed by prolific master Roy Ward Baker ("Quatermass and the Pit", "The Vampire Lovers", "Scars of Dracula"), this bizarre take on Stevenson's "Dr. Jeckyll and Mr. Hyde" accomplishes to be creepy and darkly funny at the same time.The regretfully underrated Ralph Bates stars as the eponymous brilliant scientist Dr. Jeckyll, who experiments in order to create a serum which is to make human life spans longer. In this film, he does not simply turn into a bad man when he tests the serum on himself, but into a female - more precisely into the stunning Martine Beswick! And the beautiful, but unscrupulous 'Sister Hyde' will do anything to stay..."Dr. Jeckyll and Sister Hyde" is doubtlessly one of the most bizarre Hammer films, and one of the few 'mad science' themed films Hammer made outside their brilliant "Frankenstein" cycle starring the great Peter Cushing (another one being "The Horror of Frankenstein" in which Bates played the eponymous Baron). Other than Dr. Jeckyll, the film also includes other popular Horror themes, namely the real-life events surrounding Burke and Hare and the Jack the Ripper case (though, in real life, Burke and Hare committed their crimes sixty years before Jack the Ripper, but then - who cares?). The film is terrifically set in late 19th century London, the dark and foggy alleys of which Hammer recreates with the usual Gothic greatness.Ralph Bates was a great actor and he makes a fantastic, sinister Dr. Jeckyll in the lead here. The ravishing cult-siren Martine Beswick (who was a Bond girl twice, in "From Russia With Love" and "Thunderball", and who also stared alongside Raquel Welch in Hammer's 'Cavemen vs. Dinosaurs' flick "One Million Years B.C. in 1964) is great as Sister Hyde; Miss Beswick is stunningly beautiful, but it is quite difficult to enjoy her beauty knowing that she is the female incarnation of Ralph Bates. Susan Broderick is very cute and likable as the neighbor girl who falls for Dr. Jeckyll, whereas her annoying brother (Lewis Fiander) is intrigued by Sister Hyde."Dr. Jeckyll and Sister Hyde" is simultaneously a suspenseful and creepy and often hilariously comical. In good Hammer tradition, the film profits from a great photography, Gothic set-pieces and a great score. The film maintains a creepy atmosphere from the beginning to the end, and is full of pitch-black morbid humor. Overall, this is a film that should be seen by any Horror fan. My fellow Hammer-fans in particular cannot allow themselves to miss it.
