The fantastic and terrifying things continue in the film Blacula where Prince Mamwaldi was sent by the elders of the African nation to seek the help of Count Dracula in suppressing the slave trade. Instead, Dracula laughs at this demand and hurts Mamoaldi after a fight with the disciples of Dracula, Mamuwalde is transformed into a vampire. Dracula is cursed as 'Blackola' and imprisoned in a sealed coffin in a hidden cellar under the castle. Luva is also imprisoned in the cellar and left to die.
It's redeemed somewhat by a cool soul soundtrack and a lead performance by the classically-trained Marshall, who displays a reverence for his iconic role that the filmmakers could have heeded.
William Marshall brings considerable nobility to the lead role - no mean feat when you've got patches of hair glued all over your face and keep turning into a giant bat.
