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.

Why it matters

A moody, late-period Amicus take on “Dr. Jekyll and Mr. Hyde” that pits Christopher Lee’s brooding intellect against his monstrous alter ego in a fog-drenched London.

  • Lee and Cushing together again, trading their now-iconic Hammer roles for a more restrained, psychological duel.
  • Intravenous drugs replace potions, reflecting early 20th-century anxieties about science probing the subconscious.
  • Less splashy than its Hammer counterparts, it leans into atmosphere and eerie restraint over gore or shock.
  • Perfect for fans of classic British horror who appreciate subtle period details and a slow-burn descent into madness.
