Continuity mistake: When Highway first assembles his men, it is meant to be very early morning (5:00 am.). Judging by the very short lengths of the shadows, it is quite obvious that it is around noon.

Continuity mistake: When Robert DeNiro renounces his vows of obedience, he enters the room with his hair tucked behind his ears. During the conversation with Jeremy Irons, the camera cuts away and returns showing that DeNiro's hair has changed style - the camera then cuts away a couple of times and when it returns his hair is behind his ears again.

Continuity mistake: In the scene where Steph is in her second show, there are at least 2 different horses. The manes and tails go from being braided to being unbraided. Also, the breeches change from grey to beige. One of the horses before her round, a chestnut, has one sock, then none, then three, etc. There were multiple (I counted at least 7) horses that played the part of Lightning, who was supposed to be registered with the Jockey Club, which is the Thoroughbred registry. Most of the horses that played him were not even close to being Thoroughbreds.
Continuity mistake: When the football players are trying to chase Lucas off of the field, Lucas is not wearing or carrying his helmet, and it isn't seen anywhere near him.

Continuity mistake: In the scene where Remy finally figures out that Ann has some serious questions about his dept., he pushes her against a tree. When the camera is on him, her necklace has swung around to the back of her dress. When the camera is on her, the necklace is 1/2 inside and 1/2 outside the front of her dress. This switches back and forth several times.

Continuity mistake: After the car accident, a man in a black hat and coat runs up to the left-side rear window of Patton's car, taps on the glass, then peers into the car.

Continuity mistake: Poirot met Ariadne Oliver who invites him to the "murder hunt." Poirot and Hastings then get on a boat to head there. As they sit on the boat, there are a few extras, led by an easily identifiable lady in a yellow sweater, that move up the stairs of the pier and reach the top. The boat slowly takes off, and about 10 seconds later we see the pier again, with again those same people from before just reaching the top of the stairs. (00:02:25)
Continuity mistake: To reach Poirot, Hastings walks through the Acapulco airport with two ladies (one with a white jacket, light blue skirt, updo, carries a large brown suitcase, and another one with short hair, glasses, white trousers) that are both in front of him AND behind him, depending on the camera angle.
