The townspeople have had enough! With the burgomaster's approval, the Castle Frankenstein is finally destroyed for good, but the explosions free The Monster from the sulfur pits below! Ygor has also miraculously survived, and the two escape to the small town of Vasaria, which is home to Dr. Henry Frankenstein's second son Ludwig. Using a treatment of his own design, the younger Frankenstein hopes to replace The Monster's defective brain with a healthy one, but Ygor seems to have other plans! GHOST OF FRANKENSTEIN revisits similar themes to the previous production, with Sir Cedric Hardwicke assuming the role of Ludwig Frankenstein this time around. Unfortunately, The Monster not only receives less screen time, but he is reduced even further into a lumbering oaf. Boris Karloff is greatly missed, and Lon Chaney Jr.'s zombified performance lacks personality. It is Bela Lugosi who comes through once again with another playful performance as the conspiring Ygor. GHOST OF FRANKENSTEIN would be one of the first films to show the downward decline of the Universal monster movies, but series crossovers would give The Monster a few more jolts of energy.
