Continuity mistake: When Poirot sits down with Nadine Boynton, her hat is in a different position on the table in each shot - just look at the flower. (01:01:50)
Continuity mistake: Interviews at the American Colony Hotel in Jerusalem. At quarter to 4 Lennox fixes his mother's wristwatch; the sunlight is much dimmed down in the shot when she waves him off. (01:00:25)
Continuity mistake: Poirot wants to interview Lennox Boynton at the hotel, where he is having a toast with his wife. The wife leaves the table picking up her hat. Under the hat there's a plate with a napkin on it, untouched, but when Poirot sits at the table, the napkin has been used, or at least it's not resting neatly on the plate anymore. (00:59:20)
Continuity mistake: As Poirot is attempting to leave Lord Peel's office, Miss Quinton says that she's going to visit Petra with Mr. Cope. There's a cut mid-sentence (those are never good to see), and while her position is almost flawless continuity-wise, in the background the curtains on the left window are parted and away from the wall in the second shot, were straight in the first take. (00:57:30)
Continuity mistake: Poirot tells the doctor that if she 'put the clock back two hours' she would have protected Raymond. During the dialogue, the extras in the market on the background don't carry between cuts, or do it wrongly, like the man with a basket that walks next to the car coming from different directions. (00:52:50)
Continuity mistake: After 'behaving like a man' kissing without consent, Raymond says bye to Sarah; he says "There's something I have to say, and do, to prove you that..." The shadow cast on her chest changes as the camera angles change, on and off her necklace. (00:43:10)
Continuity mistake: When Raymond invites Dr. King at the postprandial trek, his hand is right next a large crease on the towel, completely ironed out when the angle changes. (00:41:30)
Continuity mistake: Poirot waves goodbye from Carbury's car as they leave for a tour of Acre. Sarah King waves back. Behind her in the background David Soul is at his own table, sitting staring ahead. Cut to Emily suggesting everyone to go for a walk; Soul is standing, wearing his hat already and facing the other direction. And it's a shot supposedly in continuity, because the same extra is walking outside the tent in both. (00:40:00)
Continuity mistake: After the beatdown, Cope clutches in hand his ill-advised gift to Nadine as he says "It was just a figure of speech." It's closed, but when he gets up it's open. (00:23:55)
Continuity mistake: Lennox pulls out of his jacket the infamous cigarette case. In the reaction shot, Carrie Fisher's fingers are curled, in the wider angle they are straight along her cheek. Notice in this shot also Carol, with her arms down her sides. Next shot and she has her hands clasped. (00:23:45)
Continuity mistake: On the ship, Emily plans to kill her lawyer who just left her cabin. She holds the bottle of heart medicine, and in close-up the fingers are positioned differently on it. (00:20:05)
Continuity mistake: Emily Boynton tells her lawyer to stop the affair with her daughter-in-law and leave. He threatens her (not quite clear with what) and tells her "I want those children of yours to have a chance." Notice Emily's shadow, perfectly clear under the window. Next shot, and there's no shadow. (00:19:15)
Continuity mistake: Nadine tells her husband Lennox that they should disappear when they hit Jaffa. Lennox asks her "What do we use for money", his left arm folded, hand up. Close-up, and it's hanging all the way down. (00:17:30)
Continuity mistake: When Poirot moves across the beach volley (ship volley?) court, a girl in an ample blue skirt is moving left to right towards him, and is completely gone at the cut. (00:16:45)
Continuity mistake: Poirot's stomach is upset by the effluvia of the 'dead duck' that some random prankster exposes in front of him. Visible fumes are in front of Peter Ustinov, immediately gone in the wider angle. (00:14:25)
Continuity mistake: When Miss Quinton finds her lost cigarette case, Dr. King in the background is laughing. She changes position, but in Poirot's reaction, which should be in perfect continuity since the quarrel does not pause, she is sitting with her arms perfectly still. (00:14:00)
Continuity mistake: Nadine reads Cope's inscription on the cigarette case in close-up. One of his fingers is on the right side of the box, and it's absent in the next angle. And when he closes it, Carrie Fisher's right hand which was lowered, is at bosom level. (00:12:00)
Continuity mistake: Hearing that Cope is around, Nadine asks "He's not here, is he?" as she stands up from the bench. Without her handbag, that is suddenly there at the cut. (00:09:50)
Continuity mistake: The family is sightseeing London, and the eponymous Tower. A yeomen warder points up; Nadine is looking where he's pointing assuming a different position in the two shots, with the sunlight being as well different. (00:05:45)
Continuity mistake: After the will was read, Mrs. Boynton tells the 'children' that she has a lovely surprise. Carrie Fisher in the wide angle changes position leaning her chin against the back of her hand, and repeats the gesture in a subsequent shot. (00:04:15)
