If you’re the daughter of Frankenstein and you need a serum to make you eternally young, there’s only one man’s whose blood will work. That would be Santo. And that’s all we really need to get this movie rolling, right? Also, to make things even more awesome, Dr. Freda Frankenstein has several monsters in her employ, including the half-human, half-ape Truxon and a very Universal Monsters looking version of her father’s creation that she has named Ursus*.
She also kidnaps Santo’s girlfriend Norma and hypnotizes her into cutting out his eyes with a knife because life is cheap in Mexico and our hero has already turned down the evil woman’s advances.
I have a weakness for the female side of the Frankenstein family tree — witness Jesse James Meets Frankenstein’s Daughter and Lady Frankenstein — and this film has that plus lucha libre and ends with Santo fighting Japanese wrestler Yamaguchi for the title.
After this, Santo would battle Dracula, a wolfman and Dr. Frankenstein himself. Gina Roman, who played Freda, was also in La Venganza de las Mujeres Vampiro as the dreaded Countess Mayra.
*They’re both played by Gerardo Zepeda who was also in El Topo, Night of the Bloody Apes, Santo and Blue Demon Against the Monsters — in which he played Ciclope and a zombie — and so many more movies.
