I, Monster is a 1971 United Kingdom horror and science fiction film directed by Stephen Weeks about Dr. Marlowe, who experiments with drugs to release inner inhibitions, resulting in the emergence of his monstrous alter ego, Mr. Blake.

Programmer's Pick

Christopher Lee and Peter Cushing face off yet again, but this time it’s Lee vs. himself in a one-man descent into Victorian madness. Amicus gives the Jekyll & Hyde formula its own sinister twist, swapping names but not the deliciously monstrous transformations.

Overview

I, Monster reimagines the infamous Jekyll and Hyde story in Victorian London with Christopher Lee as Dr. Charles Marlowe, a psychiatrist whose experiments with a mind-altering serum bring forth the sinister Mr. Edward Blake. Each injection strips away more of Marlowe’s restraint, and his monstrous alter ego becomes ever more dangerous. Peter Cushing lends his signature gravitas as Dr. Frederick Utterson, Marlowe’s increasingly concerned friend. This Amicus production combines gothic atmosphere, psychological horror, and a touch of science fiction, focusing on the consequences of scientific hubris and the duality of human nature. The film’s period setting and strong performances drive this tense, cerebral horror adaptation.
