Scientist Dr. Henry Jekyll is intelligent and diligent, but also uptight and extremely serious about his work. When his friend, Sir George Carew, takes him to a show featuring the sensual Miss Gina, an aroused Jekyll sets out on a quest to separate man's saintly and sinful sides. His experiments succeed, and his evil alter ego, Mr. Hyde, is created. As the doctor uncontrollably alternates between Jekyll and Hyde, danger looms. Considered by many to be the first great American horror film, John S. Robertson´s Dr. Jekyll & Mr. Hyde allowed stage legend John Barrymore to deliver his first virtuoso performance on film. Blending historic charm with grim naturalism, this version of Dr. Jekyll & Mr. Hyde is one of the more faithful of the many screen adaptations of Stevenson´s story, recounting a visionary scientist´s ill-fated attempts to unleash the human mysteries that dwell beneath the shell of the civilized self.
