'White Zombie'

[1932] Arguably the first-ever zombie film, this low-budget indie hews closer to the voodoo origins of zombie lore than later flesh-eating versions made popular by Romero, Fulci, and others. The real draw is Bela Lugosi as Murder Legendre, who commands an army of the undead, as well as the mist-filled studio backlots that effectively stand in for the film's Haitian setting.
