Las Noches del Hombre Lobo is a lost 1968 Spanish horror film that centers around the werewolf Count Waldemar Daninsky, played by Paul Naschy. It has been credited as the second part of Paul Naschy's 12 "Hombre Lobo" films. However, it's been heavily disputed if the film was ever made or exists at all. No one, including Naschy himself, has ever viewed the film and it has never seen a theatrical or home media release.
