The Mark of the Wolfman

La Marca del Hombre Lobo (English title: The Mark of the Wolfman), is a 1968 3-D Spanish horror film, the first in a long series of films about the werewolf Count Waldemar Daninsky, played by Paul Naschy. The film was also known as Hell's Creatures: Dracula and the Werewolf, The Nights of Satan and Frankenstein's Bloody Terror (the latter despite the fact that the film has nothing to do with either Frankenstein or his bloody terror). Naschy followed up this film with his 1968 film Las Noches del Hombre Lobo (which is today a lost film) and his 1969 film Los Monstruos del Terror.

Plot
A drunken Gypsy couple spending the night in the abandoned Wolfstein castle accidentally resurrect the werewolf Imre Wolfstein when they remove the silver cross from his corpse. Once alive, he not only kills the Gypsy couple, but also wreaks havoc on a nearby village. The villagers attribute the attack to ordinary wolves, and in response, form a hunting party to kill off the animals. While on the hunt, Count Waldemar Daninsky is attacked by Imre Wolfstein and is afflicted with lycanthropy. After killing innocent victims in the midst of his transformation, he seeks help from specialists, Dr. Janos de Mikhelov and his wife, who turn out to be two vampires, who then prey on both Janice and Rudolph, Waldemar's friends. The vampires revive the first werewolf, Imre, from the dead, and force the two werewolves to battle each other. Waldemar kills Imre Wolfstein with his fangs and then destroys the two vampires, only to be killed in turn by a bullet fired by Janice, the woman who loved him most.

Production
Paul Naschy is the stage name of the late writer and actor Jacinto Molina. Because La Marca del Hombre Lobo was being financed by German investors, it was felt that Molina needed a Teutonic-sounding pseudonym. “Paul” was an homage to the Pope at the time, Paul VI, and “Naschy” was inspired by a well-known Hungarian Olympic athlete, Imre Nagy. La Marca del Hombre Lobo was the first in a long line of werewolf films that would make Paul Naschy world famous.

In the United States, the film was called Frankenstein's Bloody Terror, solely to satisfy the distributors' need for a second "Frankenstein film" to pad out a planned double feature release. To justify this odd choice of title, a specially created animated opening sequence explained that a branch of the Frankenstein family became cursed with lycanthropy and took the name Wolfstein. American producer Sam Sherman needed to fill 400 playdates for his film Dracula vs. Frankenstein, which at that time was entangled in a legal stand-off with an unscrupulous film lab contracted to produce the release prints. The 400 theaters in question had been promised a Frankenstein film, and Sherman was determined to give them one. Both films thus ran together in 1974 in American theaters.

La Marca del Hombre Lobo was filmed in Jan Jacobsen’s Hi-Fi Stereo 70 3-D format. When Sherman learned this, he was persuaded by other investors to hire optical effects maestro Linwood Dunn to create single-strip, over-and-under 35mm prints for American release. The final results were reportedly beautiful to look at when projected through high-quality 3-D lenses (such as those created by Robert V. Bernier for Space-Vision). But a celebrity-studded Hollywood premiere was completely undone when Sherman’s fellow investors provided shoddy acrylic lenses for the projectors.
