Villain(s)  Mr. Edward Hyde

Actor(s):  Paul Massie, Dawn Addams, Christopher Lee, David Kossoff

Brief Description  Released in the US as House of Fright, The Two Faces of Dr. Jekyll is a 1960 British horror film by Hammer Film Productions. Directed by Terence Fisher, the film stars Paul Massie in a dual role alongside Dawn Addams and Christopher Lee. It inverts Robert Louis Stevenson's classic tale by making the alter ego, Edward Hyde, handsome and charming rather than disfigured, while Dr. Jekyll is a older, stern, and neglectful husband.

Plot:
In 1874 London, Dr. Henry Jekyll is an isolated, bookish scientist completely absorbed by his fringe research into freeing the dual natures of the human mind. His obsession leaves him socially awkward, emotionally distant, and utterly oblivious to his surroundings. Because of his neglect, his beautiful young wife, Kitty Jekyll, feels starved of passion. She is trapped in a secret, reckless affair with Jekyll’s suave, profligate friend, Paul Allen. Allen is a manipulative gambler and a freeloader who shamelessly abuses Jekyll's financial generosity to cover his heavy debts.

Ignoring the warnings of his colleague Dr. Littauer, Jekyll tests his newly perfected transformation serum on himself. Instead of turning into a hairy, hunchbacked beast like in traditional adaptations, his old, bearded, and reserved persona melts away. He transforms into Edward Hyde: a clean-shaven, dashing, and extraordinarily confident young man. Initially, Jekyll is exhilarated by the raw freedom of his alter ego. Guided by the unsuspecting Paul Allen, Hyde begins to frequent the seedy and exotic underbelly of London's nightlife. Hyde is entirely devoid of a moral compass; he behaves like a refined sociopath, smiling coldly while indulging in deep debauchery.

Hyde quickly discovers that Kitty is cheating on Jekyll with Allen. Fueled by Jekyll's deeply repressed resentment and anger, Hyde decides to use his charm to orchestrate an intricate, sadistic revenge plot. Hyde feigns friendship with Allen, actively encouraging his destructive gambling habits and luring him into deeper financial ruin. Ultimately, Hyde forces Allen into a corner and brutally murders him by letting a wild python loose on him during a cabaret act. Attracted to the dark, unfaithful side of Kitty's personality, Hyde effortlessly seduces his own wife. He forces himself into her life, stripping away her dignity. When Kitty discovers the horrifying truth—that this handsome monster is actually an extension of her dull husband, and that he has orchestrated Allen's death—she is driven to complete despair and commits suicide by jumping from a balcony.

As the story progresses, Hyde grows exponentially stronger. The transformations begin occurring at will, and Hyde actively fights to suppress Jekyll permanently. In a desperate, final bid for control, Hyde attempts to frame the weak, fading Dr. Jekyll for his own horrific crimes. However, in an unusual departure from Stevenson's novella, the Jekyll/Hyde character does not die at the end. Instead, during a final confrontation with the authorities, the psychological trauma breaks the illusion, and Hyde involuntarily transforms back into a haggard, broken Dr. Jekyll in front of witnesses, leaving him trapped to face legal judgment for the atrocities his alter ego committed.
