Be sure and watch the uncut version with the title "The Mask of Satan," not the censored "Black Sunday" copy, to get the full effect of this living dead masterpiece of Italian cinema. More a movie of the undead than a vampire flick, it reminds the horror aficionado of a Val Lewton film from the 1940's, especially "The Leopard Man," not that "The Mask of Satan" is about leopards, but the mood and atmosphere are similar.
The film is about a woman of darkness and her mate who were executed for witchcraft two centuries before the Napoleonic period of European history. The most gruesome feature of the execution involved nailing a mask of Satan to their faces by means of a giant sledgehammer before they were entombed. By accident two hundred years later a doctor and his assistant while journeying through the region by coach on a dark stormy night filled with eerie devilish sounds, the doctor removes the mask from Princess Asa Vajda supposed corpse. Now Princess Vajda and her fiendish companion become free to seek their revenge. Their evil is released on the world and must be stopped.
This is undoubtedly director Mario Bava best film. The marvelous camera work draws the viewer into the maelstrom of darkness and evil through innovative movements and angles. The shadowy settings where the actors are posed in ominous fashion are unforgettable. One obvious inspiration for Bava was the contemporary British Hammer horror film popular in America, especially with the drive-in crowd. The arrival of Katia Vajda with what appear to be the dogs of Hell, standing like a silhouette of damnation, reminds one of a Caspar David Friedrich painting from the German Romantic art movement of the Napoleonic era. One wonders if the director of "The Omen," Richard Donner, patterned his creepy scene in the cemetery with the Rottweilers after this scene in "The Mask of Satan."
This movie remains a must see for horror fans, somewhat of a lost treasure.
