Peter Cushing stars as the evil Baron Frankenstein who,driven out of his homeland of Bohemia,has set up shop in an English boarding house,where he blackmails the lovely Miss Spengler,who has inherited proprietorship of the establishment from her ailing mother,and Miss Spengler's dashing young fiancé Carl into helping him with his diabolical experiments.Through Frankenstein's great good planning or great good fortune,Carl is a doctor employed at the mental hospital in which resides the infamous Dr. Brandt,Frankenstein's one time research associate and the very man Frankenstein came to England to see,now a hopeless madman.With Carl's help,Frankenstein plans to abduct Dr. Brandt and cure his insanity..."Frankenstein Must Be Destroyed" by Terence Fisher is brilliantly directed film.The script by Ben Batt is truly intelligent and Freddie Jones's creature is the most interestingly complex and well played of all the Hammer's Frankenstein monsters-indeed it is the only one to come anywhere near Mary Shelley's novel and her conception of an intelligent and literate creation come to taunt its creator for the condition inflicted on it.Give this one a look.8 out of 10.
