Continuity mistake: When the butler tells Linnet Ridgeway that the architect isn't there yet, she turns towards him dramatically in the first shot, and in the following she again turns towards him. (00:04:30)
Continuity mistake: Mia Farrow begins running towards her friend Linnet holding a box of sweets in her left hand. The next shot shows her holding it with both hands, and then she switches to just the left. (00:04:50)
Continuity mistake: When Jackie tells Linnet that she has a favour to ask, she holds the box at different height and tilt during the conversation, and the position of her fingers on it changes as well. (00:05:40)
Continuity mistake: In the introduction of her character, Bowers tells Mrs. Van Schuyler "What do I care" to her threat. She sits straight, with the cigarette hand slightly below chin level. In the wide angle she sits back, with the cigarette hand resulting at a higher position. (00:09:45)
Continuity mistake: When Linnet and Simon reach the pyramids, their horses change abruptly position as they dismount to tie them to the stone, and change distance again at the next overhead shot. (00:11:00)
Continuity mistake: On the top of the pyramid, Linnet whispers "Silly" to Simon's question about her happiness, and she holds him close. Her thumb is on display at the side of his bicep, but at the cut it's on the part of the arm that faces her. (00:12:20)
Continuity mistake: On the Neter Menkaura pyramid, Linnet shouts; "She's following us about, deliberately" in a close-up with all the hair in front of her shoulders, contrasting with the previous angle, where her hair was behind the shoulders. (00:12:55)
Continuity mistake: When Simon frees the horse's reins from under the stone, the saddle blanket all of a sudden folds between shots. (00:13:25)
Continuity mistake: Simon and Linnet regain their wits after the unexpected encounter with Jackie on top of the pyramid of all places. They make out, and Linnet's hair changes radically position depending on the camera angle throughout the whole snogging. (00:14:35)
Continuity mistake: When Ferguson says that he's "observing the decline of the capitalist system", he holds 'Das Kapital' at the top corner. His hand moved from the position in the previous shot, which was at the bottom of the same side, and changes again at the cut and switches back and forth as the angles alternate. (00:17:15)
Continuity mistake: When Poirot tells Jackie "Turn your back on the past", Mia Farrow is wiping her neck, but in the next shot her handkerchief is pressed against the cheek instead. (00:23:25)
Continuity mistake: Poirot watches Jackie leave the hotel seemingly falling for Simon's ruse. He's having breakfast; when he puts the croissant in his coffee, the hand holds the brioche with its flat side upwards. Ustinov in close-up is eating the brioche with the curved side up. (00:27:00)
Continuity mistake: During the conversation when Bette Davis' character is introduced to Lois Chiles', the background changes inconsistently between shots. (00:32:40)
Continuity mistake: In the first conversation between Linnet and Mrs. Van Schuyler, Bette Davis' hands are positioned differently depending on the camera angle - either the right hand or the left hand on top of the other. (00:33:00)
Continuity mistake: Bowers and Van Schuyler retire in the cabin leaving Linnet behind them. The deck is dusky, but in the reverse angle that follows, there she is, on the fully sunlit deck. (00:34:30)
Continuity mistake: Mrs. Salome Otterbourne sits next to Linnet. Linnet is holding an object between her hands; when Salome says that writers can get flowery in their speech, Linnet replies drily, but the hands changed also position. They were at the same level in the first shot, they are one on top of the other in the follow-up. (00:35:00)
Continuity mistake: Linnet is enraged because apparently Salome Otterbourne featured her in her fiction book and equated her to "a nymphomaniacal baboon." Nonsense aside, she gets up holding the book. Angela Lansbury is looking at her, left hand upturned. Cut, and she is staring at her with both hands in her lap, downturned. (00:35:35)
Continuity mistake: When Poirot and race play checkers while Pennington tries to swindle Linnet, a single piece lies at the side of the board in the wide angle, but in the closer views you can count 3. (00:36:05)
Continuity mistake: Pennington sits at Linnet's table and begins putting down contracts to sign. David Niven in the background looks at him, closed fist below the nose, but in the next shot he's staring at him stroking his temple and moustache, and at the following cut he changed position again. (00:36:20)
Continuity mistake: When Poirot and the other tourists are walking in the section of the temple of Karnak with the ram statues, they cast shadows towards the right of the screen, their left. The action focuses on Salome extolling the priapic virtues of the beasts, and the shadow she and the professor cast is at their back. (00:42:30)
