However, after de Ossorio finished the film, the producers decided to make the uncle an actual vampire in the English-language version, and added a low-budget disintegration scene to the finale of the English-dubbed prints that completely contradicted the plot.
Strangely, many of the actors who regularly appeared in Jesus Franco's films also worked for Amando de Ossorio, such as Jack Taylor, Montserrat Prous, Paul Muller, Fernando Bilbao, Luis Barboo, Rosanna Yanni and Kali Hansa.
Unfortunately de Ossorio's last horror film, the 1984 Sea Serpent (which had been his dream project for many years) was a disappointment to him due to the very low-budget special effects he was forced to utilize, and led him to retire from filmmaking in 1984, at age 66.
During the interview, de Ossorio complained about the pitifully tiny budgets he was always forced to work within, and he lamented that in almost every case, the finished project never came close to what he had envisioned when he first conceived each film.
In 1993, de Ossorio was shopping around a script for a fifth Blind Dead film, to be called "The Necronomicon of the Templars", but he failed to interest a producer in the project.
