La Noche de Walpurgis (Walpurgis Night, released in the United States as The Werewolf vs. The Vampire Woman, and in the UK as Shadow of the Werewolf [theatrical] and Werewolf Shadow [video]), is a 1970 Spanish horror film starring Paul Naschy, the fifth in a series about the werewolf Waldemar Daninsky.
 This film was directed by León Klimovsky and written by Naschy and Hans Munkel, and is generally regarded to have kickstarted the Spanish horror film boom of the Seventies, due to its awesome box office success upon its release.
 Patty Shepard was so convincing as the vampiric Countess, it was thought at the time that she might replace actress Barbara Steele as Europe's reigning horror queen.
 Klimovsky filmed many of the scenes in slow motion, to add to the otherworldliness of the film.
