Dracula: Prince of Darkness (1966)

Directed by Terence Fisher

Whilst vacationing in the Carpathian Mountain, two couples stumble across the remains of Count Dracula's castle. The Count's trusted servant kills one of the men, suspending the body over the Count's ashes so that the blood drips from the corpse and saturates the blackened remains. The ritual is completed, the Count revived and his attentions focus on the dead man's wife who is to become his partner; devoted to an existence of depravity and evil.
