Death on the Nile (1978), featuring Peter Ustinov in the celebrated Christie role of lead detective, in this case Mr Poirot, utilizes the lovely scenery along the Nile River of Egypt, including the majestic Abu Simbel, to contrast the Divine serenity of the Pharaohs of Egypt, demi-gods themselves, with the sordid nature of the then-current English high-class, who are collectively resentful of the American whose family deprived them of their wealth. They are bitter, grasping, and pretending that they still can lord it over everyone else: Egyptians, English lower classes, and those uppity Americans.
Throw in a few charming American anachronisms emitted by the Egyptian boat manager, Mr Choudhry, and this is a pleasant enough manner for passing a couple of hours. Put the butter on the popcorn, folks, and sit back and enjoy big Hollywood names having fun.
