The ghost of Frankenstein : Son of Frankenstein / Universal Studios.

The ghost of Frankenstein: When Ygor brings the monster to Frankenstein's country castle, the doctor decides that a brain transplant might be in order. While Frankenstein thinks the transplant should be of a healthy and sane brain, Ygor plots with Frankenstein's unscrupulous colleague Dr. Bohmer to transplant Ygor's brain instead, so that he can rule the world using the monster's body. Their plan turns sour when the monster becomes malevolent and goes on a rampage in the nearest town. Son of Frankenstein: The son of Dr. Frankenstein returns to his ancestral castle twenty-five years after the infamous monster's "death." There he meets Ygor, a mad shepherd who is hiding the body of the creature. The young doctor revives his father's creation in the hope of rehabilitating him and clearing the family name.
