Continuity mistake: When the shark is pursuing Bond through the sunken ship, you see first Bond, then the shark coming through the door. The bubbles generated by his movement abruptly disappear as the shark comes through, revealing too obviously the stitching together of the two sequences. (00:50:50)
Continuity mistake: When Bond and Felix Leiter are underwater snooping around Lago's boat, Felix can be seen in diving gear minus hat. After Bond gets sucked into the boat and Felix returns to land, you can see Felix take off the hat that was not in the previous scene. (01:30:30 - 01:32:50)
Continuity mistake: When the nuclear missiles land in the ocean, the man on the boat guides them down. On the screen in front of him, the range goes from 12 to 4 km away, but then to 5 km and 3 km away. (00:30:05)
Continuity mistake: When Bond and Domino jump into the water from Palmyra with the horse, Bond is wearing a very tight fitting brown jacket and shoes. When he emerges from the water a second later, he is shirtless and shoeless. (01:48:15 - 01:48:55)
Continuity mistake: When the horsemen arrive to where Domino is tied up, the watcher has a cigarette in his lips, but it appears in his hand in the following shot. (01:44:25)
Continuity mistake: When Nigel falls in the water, his hairstyle changes between shots. Sure there's a two seconds shot in between, but that would mean that Nigel had that short lapse to let go his suitcase, bend his head backwards, comb his hair and grab onto his suitcase again... Impossible.
Continuity mistake: Largo's men leave the fishing boat in full on wetsuits to recover the warheads but the men who retrieve them are wearing sleeveless wetsuit tops and wetsuit shorts, also the wrong wetsuits for the colder UK waters.
Continuity mistake: During the title sequence two villains are playing an implausible-looking chess game which includes two black bishops both positioned on black squares. Black takes white's queen. A moment later we see the player putting the taken queen aside but numerous pieces have moved, including two knights and several pawns. (00:03:05)
