Gothic hangoverLee going FULL LeeCushing side-eye

Overview

HorrorScience Fiction

Christopher Lee stars in this Amicus production of “Dr. Jekyll & Mr. Hyde” where the names have been changed to Dr. Marlowe and Mr. Blake. Lee as Dr. Marlowe experiments with intravenous drugs that are suppose to release inner inhibitions. So comes forth Mr. Blake (also Lee) who gets more monstrous with each transformation. Peter Cushing plays his friend and colleague, Dr. Utterson.

Standout Aspects

Acting

Lee's physical transformation work — subtle, then suddenly NOT.

Production

Fog-drenched London sets on obvious budget, somehow more haunting.

Practical Effects

Progressive monster makeup that ages worse than the themes.

Best for:Solo: Late-night gloom when you want to feel Victorian-miserable.·Rewatch: Spot which transformation looks most like bad taxidermy.·Streaming: Perfect 70-minute commitment for horror completists.
Heads up:Disturbing: Animal cruelty scene that'll have you hissing at the screen.·Sexual Content: Repressed Victorian lust bursts through in sleazy undertones.

Deep Dive

Trivia, insights & behind the scenes

Trivia

Stephen Weeks was only 22 when he directed this, making him one of Britain's youngest feature directors — explains the ambition exceeding the budget.

Cultural

Amicus was Hammer's scrappy rival; this film's renamed characters let them dodge Universal's copyright on the Stevenson adaptation while keeping the exact same story.
