Curse of Frankenstein was the "breakthrough" picture for the fabled Hammer Studios. Told in flashback, the story centers around Baron Victor Frankenstein (Peter Cushing), a dangerously arrogant scientist who takes it upon himself to play God. Using portions of dead bodies, Victor fashions a synthetic monster (Christopher Lee) with a bad attitude. In a radical departure from the Frankenstein canon, it is the imperious Victor who orchestrates the film's two murders by "borrowing" the brain of a learned professor, then leaving his next victim at the mercy of the monster. In 1958, the film spwaned the sequel Revenge of Frankenstein.
