U.S. titles: House of Fright and Jekyll's Inferno) is a 1960 British horror film directed by Terence Fisher and starring Paul Massie, Dawn Addams, Christopher Lee and David Kossoff.

[3][4] The screenplay was by Wolf Mankowitz, based on the 1886 novella Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson.

Ignoring the warnings of his colleague and friend Dr. Ernst Littauer, the middle-aged, mild-mannered Jekyll concocts a chemical potion which he hopes will help him learn the depths of the human mind.

Hyde then kills a man in Jekyll's laboratory by shooting him in the back and sets his body up at a desk in order to frame his other self for his crimes.

Some time later, Hyde, Littauer and the police attend the coroner's court, where it is found that Jekyll was responsible for the deaths due to his dangerous experimentation with drugs, and that he then took his own life.

[8] Dr. Jekyll has brown eyes and wears a full beard with rather long hair and bushy eyebrows, whereas Mr. Hyde is blue-eyed, clean shaven and has a shorter haircut.

"[9] Variety gave the film a good review, praising Paul Massie for an "interesting performance" and Jack Asher for "colorful and sure" camerawork.

"[11] Harrison's Reports graded the film as "Fair", adding, "Horror fans will hardly be scared by this well-mounted British import... Paul Massie does the best he can in the poorly written twin role.

Ultimately, the critical and commercial flop of Mary Reilly (1996), TriStar Pictures' own Jekyll and Hyde film, and the dissolution of Dreamscape ended the project.
