Doctor Jekyll y el Hombre Lobo

After a series of scientific experiments directed towards freeing the inner man and controlling human personalities, the kindly, generous Dr Henry Jekyll succeeds in freeing his own alter ego, Edward Hyde, a sadistic, evil creature whose pleasure is murder.

As American policemen in London, Bud and Lou meet up with Dr. Jekyll and Mr. Hyde.

In foggy London Dr Jekyll experiments on newly deceased women determined to discover an elixir for immortal life. Success enables his spectacular transformation into the beautiful but psychotic Sister Hyde who stalks the dark alleys of Whitechapel for young, innocent, female victims, ensuring continuation of the bloodstained research. With each transformation Sister Hyde becomes the more dominant personality, determined to eventually suppress the frail, ineffectual Dr Jekyll forever.

Dr. Henry Jekyll believes that there are two distinct sides to men - a good and an evil side. He believes that by separating the two, man can become liberated. He succeeds in his experiments with chemicals to accomplish this and transforms into Hyde to commit horrendous crimes. When he discontinues use of the drug, it is already too late.

A strange animal attack turns a botanist into a bloodthirsty monster.

Henry Jekyll is a troubled man. His wife died of pneumonia. He wants his sister-in-law, but her father forbids any contact. And his experiments into the dual nature of man have yielded a personality-splitting drug that he has tested on himself, changing him into an uninhibited brute who seeks violent and undignified pleasures. Jekyll quickly becomes addicted to the sordid freedom induced by the drug. He can commit the most enjoyably revolting deeds, then return to his laboratory and use an antidote to change back to his original form, so that his lofty persona remains untarnished.
