Los Monstruos del Terror

Los Monstruos del Terror English The Monsters of Terror, also known as Dracula vs. Frankenstein, Reincarnator and Assignment Terror, is a 1970 SpanishGermanItalian horror film directed by Tulio Demicheli, Hugo Fregonese and Eberhard Meichsner. The last two were uncredited in the films original print. It is the third in a series of movies featuring the werewolf Waldemar Daninsky, played by Paul Naschy. It was originally slated to be called The Man Who Came From Ummo, referring to the Michael Rennie character.

Lead actor Paul Naschy also wrote the screenplay. The original shooting title was The Man Who Came from Ummo El Hombre que Vino de Ummo, but the producer changed it to The Monsters of Terror. Direction was split between two people, Tulio Demichelli and Hugo Fregonese. Filming was interrupted because of financial difficulties and also resulted in the script not being filmed as it was written. Whole segments of the script involving flying saucers and a Golem were never filmed as the result of sorely lacking funds.
