Continuity mistake: When Major Derval steps up to the co-pilots seat and sits down you can see him wearing an orange life preserver and strapping on the white four-point safety harness. However, when he removes the gamma gas from his pocket the safety harness is missing but is back in place in the next scene.
Other mistake: When the SEALs attack Largo's men, there is a scene where a SEAL swimming forward is shot with a spear gun. But the man simply doubles over; the harpoon - which should be visible protuding from his front - is not seen.
Continuity mistake: One for the wristwatch enthusiasts: Towards the end when Bond goes into the water he checks the time on his Omega. Later he looks at his watch and he's wearing the Breitling with built-in Geiger counter that Q gave him. Both shots are long and clear, probably because the watchmakers paid for them.
Continuity mistake: Near the end of the film as James Bond swims towards Palmeras, he gets out of the water to go up a flight of steps, and you see that he is wearing red shorts that are wet as he gets to the top. You then see a shot of Largo's henchmen getting into the back of a truck, as Bond goes down the next flight of steps the shorts are no longer wet, and they are now much lighter in colour.
Plot hole: It seems very convenient that Largo should have with him an entire team of men ready to do battle to over the bombs at the end of the film when he couldn't have known Bond had already got word that the bombs were in Miami. A few men to help handle the bombs yes, but he just has to have about the same number of men ready to counter balance the good guys jumping from the plane.
Plot hole: How does Fiona know about the escapades Bond has had with other women? She wasn't around when he was with any of them, if they were enemy agents they've been killed and if they were good Bond girls they're not telling the world what they did with Bond. It's not like he's blabbing to the world what he does so how does she know any of this?
Continuity mistake: When James and Felix land on the water and find the Vulcan, as James goes to dive Felix is wearing shorts, when James returns Felix is wearing rolled up trousers then back to shorts again.
Continuity mistake: As Bond reaches his car just before tossing the jet-pack into the trunk, it is clear to see that the entire rear portion of the car is covered in tree droppings, especially the rear window. However, the angle changes as he is in the car and now the car is completely clean.
Continuity mistake: Bond takes off his jet-pack and tosses it into the trunk of his Aston Martin. He tries to close the trunk lid, but it is still open a few inches as he drives away. Somehow the trunk lid appears completely closed in the next shot as he races away from the bad guys.
Continuity mistake: When Bond removes the bandage from Duval's face, he first uncovers a large square area from the nose to the hairline. In the next shot Duval's face is again fully covered except for the eyes.
Continuity mistake: In the bit where the power on the island is turned off, while Largo is getting ready in his room, you can see the moonlight that is coming through the grill of the door suddenly "turn on" as the lights go out.
Continuity mistake: When James Bond and Domino come out of the water after their underwater love scene, 007 suddenly wears a shirt and Domino's got a towel.
Continuity mistake: After Vargas is harpooned, Bond is walking quickly up the beach with Domino toward his car. He tells her to go straight back to Palmyra. Her speed boat is anchored off-shore in the opposite direction. Shouldn't she be heading for the boat and not the car?
Revealing mistake: When James Bond and Felix go out in the helicopter for the second time to search for the mising plane, at the moment when Bond is looking through the pair of binoculars, and when Felix says "you won't find it down there, that's the Golden grotto" just look how slowly the rotor blades are turning, at this speed there is no way that the helicopter could possibly fly and besides, there is hardly any noise from the engine.
Continuity mistake: One of the gadgets which Q gives to Bond is a mini air tank, "good for about four minutes of air." He's very specific about this number. In the huge climactic underwater battle scene, Bond Against The Hordes, 007 puts on the mini tank and proceeds to fight, vigorously, for a solid ten minutes without borrowing anyone else's tank. He either had gills implanted or can fight while holding his breath for enormously long periods of time.
Continuity mistake: At the carnival scene Bond gets shot in the calf, but in the underwater fight there is no mark on either of his calves.
Factual error: When the operation to plant the bombs is foiled, the Disco Volante casts off, pursued by two speed-boats and a destroyer. But how could the latter, as a large (and slow) battleship, approach the yacht without arousing suspicion?
Continuity mistake: When Bond and Felix go out for the first time to search for the missing plane, Bond's hair has a parting to the left and is wearing watch on his left arm, but at the moment when they are flying over Largo's house, Bond is looking through a pair of binoculars. As he says to Felix "separate pools for sharks, no less" his hair is now parted on the right and his watch is now on his right arm, also watch out for the mouthpiece on Felix's headphones - it changes from left to right.
Revealing mistake: When Bond is wounded and on the run from Fiona and her assassins, he tries to lose them in a parade. At one point during the chase, for several seconds, there is a dog in the frame. Even without slowing down the film one can see that the dog is stuffed.
Suggested correction: The dog is peeing in the street.
