Detective Lovelorn and the Revenge of the Pharaoh (2002)

Nils Lovelorn, blessed with a present ego and a "second self" in the form of a well-rounded super blonde called Bebe, is sent back in time by time machine. There he is to blow out the lights of a pharaoh who, 3000 years later, threatens the world with destruction as a demon. Unfortunately, his feminine second half occasionally gains the upper hand and, to make matters worse, falls in love with the blood-sucking, evil pharaoh.
