Also known as Cauldron of Blood, Blind Man's Bluff is a Spanish-made horror film long on gore but short on logic. Several beautiful models have disappeared, and the prime suspect is blind sculptor Boris Karloff, a surly and secretive sort who produces skeletal statues. Lovely model Rosanda Monteros tries to get to the bottom of the mystery, and of course nearly winds up a victim herself. The killer is not Karloff but his wife Viveca Lindfors, who hopes to sustain her husband's reputation by providing fresh skeletons for his artwork. Lindfors ends up hoisted on her own petard when she accidentally dips her arm in a vat of acid. Yeccch.
