If you haven’t watched the 1966 Hammer film, The Plague of the Zombies (John Gilling), you should. Much of it is fairly standard Hammer fare—set in the nineteenth century, stagey dialogue, filmed on artificial sets—but it has moments of real power, and it’s an important entry in the zombie tradition.
The Plague of the Zombies is a crucial link between the zombie revolution that was about to hit the screens two years later—in George A. Romero’s 1968 classic, Night of the Living Dead—and the zombie films of the 1930s and 1940s, which drew up Haitian lore and in which zombies were mindless bodies under the control of an evil (white) man.
