Beast Of Morocco (1966)

aka: The Hand Of Night

William Sylvester stars as Paul Carver, a grieving widower (both his wife and child were killed in a car accident) who takes an unusual and hazardous job accompanying an archaeologist (Edward Underdown) and his daughter (Diane Clare) on a North African tomb-hunting expedition. After their arrival in Morocco, they learn of legends involving a Moorish vampire who haunts the tomb. Before long, the lonely Paul has succumbed to the seductive charms of a mysterious woman (Alizia Gur), who begins to bend him to her will.
