Voodoo Black Exorcist (1974)

The mummy of long dormant, but powerful Caribbean voodoo priest Gatanebo gets revived on a luxury South Seas ocean liner as a big buff bald guy and proceeds to terrorize the passengers. Gatanebo beheads several folks, occasionally reverts back to his prune-faced mummified state, and falls for the ravishing Sylvia, who reminds him of his old flame Kenya.
