Paul Naschy, an actor, director and screenwriter widely acknowledged as the dean of Spanish horror films, whose dark web of credits includes “Night of the Werewolf,” “The Night of the Executioner,” “The Nights of the Wolf Man,” “Night of the Howling Beast” and “Good Night, Mr. Monster,” died on Nov. 30 in Madrid. He was 75.

The cause was cancer, his son Sergio Molina told the Spanish news agency Efe.

A bloodied veteran of more than 100 pictures, Mr. Naschy retains an ardent cult following around the world, in particular for the films he made in the 1960s and ’70s, the apex of his long career. Acting in his own films and those of other directors, writing many of his own screenplays and sometimes directing them, Mr. Naschy was responsible for a slew of movies that cheerfully explored the lurid, the violent, the sexual and not least of all the sanguinary.

Among them are “Werewolf Shadow” (1971); “Dr. Jekyll and the Wolfman” (1972); “Blue Eyes of the Broken Doll,” a k a “House of Psychotic Women” (1973); “The Black Harvest of Countess Dracula” (1973); “Horror Rises From the Tomb” (1973); “Hunchback of the Morgue” (1973); “The Orgy of the Dead” (1973); “A Dragonfly for Each Corpse” (1974); and “Cannibal Killers  Human Beast” (1985).

There are a great many others.

A review of “Blue Eyes of the Broken Doll” on the Web site blogcritics.org last year called it “an entertaining and somewhat bloody whodunit wherein an ex-con gets wrapped up with a trio of weird sisters in a remote French village,” adding, “Sex, murder, sex, sex, the actual slaughter of a pig, more sex and more murder are just some of the highlights in this enjoyable thriller.”
