Malenka, the Vampire's Niece (also referred to as Malenka, Malenka: La Nipote del Vampiro, Malenka: la Sobrina del Vampiro, The Vampire Girl, and Fangs of the Living Dead) is a 1969 Spanish-Italian horror film that was written and directed by Spanish director Amando de Ossorio, and his first horror film. The movie had its world premiere on July 23, 1969 in Italy and was released in Spain in August of the same year. The film was inspired by similarly themed Italian and British vampire films that were releasing during the same time period such as Dance of the Vampires, and is one of the first vampire films to originate in Spain. It has been credited as being "the 1969 picture that hammered the final nail into the cinematic coffin of the bomb-shelter-era bombshell Anita Ekberg", as well as being "one of the most original gothic examples of Spanish horror". Boris Karloff was initially approached to star in the film, but he eventually turned down the role following contractual wrangles. (Boris wound up dying before the film was completed anyway.) There are two alternative endings for the film, a rationale-type ending in which the vampire turns out to be a hoax, and a supernatural ending which was added only to the English version of the film. The musical score by Carlo Savina was later reused in the 1971 low-budget horror La notte dei dannati. Julian Ugarte played the vampire uncle, fresh from his appearance as the vampire in Paul Naschy's classic La Marca del Hombre Lobo (1968).
Upon its release producers offered "free psychiatric care" for anyone disturbed by Malenka or by two of the other films they were showing, Curse of the Living Dead or Revenge of the Living Dead.
