Dr Jekyll and Mr Hyde become Dr Marlowe and Mr Blake in a vapid attempt to give a Freudian psychological interpretation to Robert Louis Stevenson's oft-told tale. Christopher Lee is convincing as the doctor meddling with a dangerous formula, and the Victorian London atmosphere is well captured, but director Stephen Weeks's inexperience means that any complex themes are quickly abandoned, and the end result is flatter than you might expect.

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.
