aka Blood of the vampires,
aka Creatures of Evil (UK),
aka Vampyrernes forbandelse (Denmark)
Directed by: Gerardo de Leon
Original trailer in it's original aspect ratio and pretty worn after having been played at hundreds of drive-ins (I assume). The video quality is top notch, though; HD (1080p)
CURSE OF THE VAMPIRES is great! I highly recommend you check out Andrew Leavold's reveiw here.
