La Marca del Hombre Lobo (translation: 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 claimed he followed up this film with his 1968 film Las Noches del Hombre Lobo (which is today a lost film, if indeed it was ever made at all, since no one has ever seen it) and his 1969 film Los Monstruos del Terror.
