Continuity mistake: In the scene at the market in Jerusalem, when Poirot tells Dr. King "Offer him five", the merchant at the stall is standing in front or behind a trinket with a large rectangular pendant, depends on the camera angle. (00:49:45)
Continuity mistake: Poirot is in colonel Carbury's office to convince him not to rule the death as natural. He tells Carbury that he will tell him who the culprit is.

(00:48:50)
Continuity mistake: Poirot asks Sarah King if the bottle of digitalis in her bag was empty. In the wide angle his index finger is placed on the neck of the bottle, it's much lower in the close-up. (00:47:30)
Continuity mistake: Raymond timidly approaches Dr. King at the buffet of the Qumran campsite. A local with a big turban walks behind them right to left to grab something behind the watermelon. Cut to a different angle for a couple seconds, and when we're back to the first, the same extra repeats the exact same movement. (00:38:45)
Continuity mistake: Carol sits down with Dr. King and begins explaining what was her mother did for a living before her marriage.

Continuity mistake: Freshly arrived to the hotel in Jerusalem, Dr. King looks down from the balcony and spots Raymond eating something at the table with his family. In the next shot, he's not munching anymore, and he's already smiling at her. (00:28:05)

Continuity mistake: When Dr. King approaches Poirot with the scopolamine syrup, in close-up Ustinov's hand is a bit lower on the glass, and, the woman in the background, who had her hand up, has it down; not that she has a choice, since you can tell she is forced to keep firmly her hand down her side to hold in place her skirt (the wind would otherwise make it flap around all over the place).
