Tony Todd (Clive Barker's Candyman, Final Destination 2) is Dr. Henry Jekyll in this blood-drenched, modern adaptation of the macabre classic. Part crime thriller, part psychological horror, The Strange Case of Dr. Jekyll And Mr. Hyde takes Robert Louis Stevenson's sinister story to chilling new depths as Mr. Hyde leaves a grisly trail while terrorizing local college co-eds. With the police bearing down on him, Mr. Hyde attacks Henry's fiancee in the demented denouement of this twisted tale that must be seen to be believed!

The Strange Case of Dr. Jekyll and Mr. Hyde is really just as much the story of Gabriel John Utterson, a lawyer and good friend of Dr. Henry Jekyll. More importantly, Utterson is a Victorian Gentleman, who is guided by a chivalry-like code to remain loyal to his friends and maintain his status in society. It is loyalty that drives Utterson to play detective in an effort to protect Jekyll from the malicious and scheming Mr. Hyde. Eventually, Utterson finds himself introduced to a world that he is neither ready to enter nor accept. The story takes place in Victorian-era England, after the Industrial Revolution. Utterson, a lawyer, and true Victorian Gentleman, discovers that his long-time friend, Dr. Henry Jekyll, has become involved with a mysterious and dangerous man named Edward Hyde. Jekyll is a tall, handsome man with a very high social status, which he is expected to maintain. Hyde is a complete opposite, short and vulgar, with an unidentifiable deformity.

While his nights are lost to him, he awakens with bloody mementos and violent memories of the screams of his victims.

Christopher Lee stars in this Amicus production of “Dr. Jekyll & Mr. Hyde” where the names have been changed to Dr. Marlowe and Mr. Blake.

Peter Cushing plays his friend and colleague, Dr. Utterson.

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.
