Boris Karloff plays Franz Badulescu, a famous sculptor and who has been blind since his wife, Tania (Viveca Lindfors) tried to murder him for his fortune. Claude Marchand (Jean-Pierre Aumont) has come to the Spanish village of Pinderera to interview Badulescu for a travel magazine. Not surprisingly, Tania and her lover (Milo Quesada) are making a second attempt on Badulescu's life, but they kill a couple of other people first, apparently so they can hide the bodies the sculptor's statues; this looks good but makes no sense. I also have no idea why the evil couple waits until there is a visitor to try something as difficult as killing a blind man...
"Cauldron of Blood," originally titled "Blind Man's Bluff" and known as "El Coleccionista de Cadaveres" in Mexico, is one of Boris Karloff's final films, released after this his death. Ironically, although Karloff was ill with emphysema, he got this role because Claude Reins was too ill to accept the part. Certainly not as bad as the final quartet of cheap horror films Karloff made for a Mexican producer in 1968, "Cauldron of Blood" is still a cheesy movie. I would recommend you check out one of Karloff's lesser known horror films from the 1930s like "The Black Room" instead.
