Blacula (1972)

An 18th century African prince is transformed into a vampire by Count Dracula, cursed with the name Blacula, and entombed in Dracula's castle after he fails to convince the Count to support him in his cause to end the slave trade. Two hundred years later, a pair of gay interior decorators transport his coffin to L.A., where he awakes with an unquenchable thirst for human blood. As Blacula pursues a woman who resembles his long-dead wife, Luva, her brother-in-law, a pathologist, investigates the string of carnage that follows in the vampire's wake.
