White Zombie (1932) is widely considered the first feature length zombie film. While genre-purists may revere George A. Romero, Victor and Edward Halperin came first.
But we're not talking about dead bodies stiched together to create new life! We're talking about complete bodies being transformed into the living dead. For...sexual purposes, if you believe the poster. My guess is that since Béla's Dracula was so sexualized (as many classic and modern interpretations of these aristocratic undead are), they tried to use the same draw by applying the motive to the Bokor.
Okay - enough of me rambling on about voodoo priests, sexy fanged dudes, literature, and pop culture. It's movie time!
That's right, you can watch White Zombie on the Internet Archive - everyone's favorite place for public domain films. You can find White Zombie here. Enjoy!
