Revealing mistake: When Largo escapes to Disco Volante, he closes the underwater hatch before Bond arrives. But the hatch can't close completely. A hole is visible (and light from behind). The hatch is obviously created in a studio, because the boat would not be able to sail - at least not that fast - with such an opening in the bottom.
Visible crew/equipment: When the colonel dressed as a woman enters his house a butler opens a glass door, as he does, for a second, a big round stage light is reflected. (00:01:45)
Continuity mistake: When Bond is at the spa and he turns the dial on the steamer, one second the man has a pink/white towel around his neck, the next it has turned blue. In addition, when it cuts back some bottles have disappeared from a nearby steamer. (00:17:05)
Revealing mistake: Near the end of the film, when the bombs are on board the mini-sub, Bond is spotted by Largo and swims away, but is chased by one of the other divers who has a fight with Bond: Just before they get to grips with one another, you can see that the jacket of Bond's underwater suit is already torn at the right shoulder.
Continuity mistake: The scene with the Aston when Lippe's car is blown up by the motor bike rider is filmed at Silverstone. You can see the Stowe grandstands in the background. (00:36:40)
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: The shark pool the thug is thrown into alternates between just deep enough for sharks, to several feet deep and back between shots.
Continuity mistake: As the man holds the gun on Angelo after his demand for more money, first the gun is at the small of his back, and a second later, it's at neck level.
Revealing mistake: In the close ups of the jet pack scenes, the wires holding Bond up are visible.
Continuity mistake: When James goes to meet Largo, there is a woman swimming laps in the pool. When she is finished, her hair covers her ears and some of her face, but, in the next shot, her hair has been combed back, making her look presentable and beautiful.
Continuity mistake: In the car chase scene, the black car chasing Bond gets blasted by a motorcycle. The back of the car explodes and is has flames twice as tall as the car. When seeing it through Bond's windshield, the car has only smoke. When the camera cuts back, the flames are huge again. Also, when the motorcycle goes to pass Bond, he looks left, but the bike passes on his right.
Audio problem: The dialogue with Largo is completely unsynchronized when he returns to the Disco Volante for the final chase and battle scene.
Factual error: The Panamanian flag on the Disco Volante is upside down throughout the film. It flew in that configuration only in 1903.
Continuity mistake: Bond's watch changes wrists several times when he speaks to the receptionist at the health farm.
Continuity mistake: When Bond meets Domino in the diving scene, when Domino is seen from below, the sky above her is overcast. In the following wide shots the sky is clear (or almost clear).
Continuity mistake: When the second SPECTRE tape is being played, in the first shot the left tape wheel - where the tape which is still to be played is coming from - is almost empty. In the next shot it is full.
Visible crew/equipment: When the red headed woman answers the phone, a row of lights are reflected on the phone head. (00:17:50)
Revealing mistake: At the end of the film in the underwater fight scene, when Bond is zooming through the water, you can see the cable pulling him along through the water
Continuity mistake: Just after Vargas has been harpooned and impaled to the tree, watch the position of Domino's hands as she says to Bond "I'm doing this for my brother for what he did to him" in between shots: When she has her back to the camera you cannot see her hands, but when you see Bond from behind, she has both of her hands on his shoulders.
Answer: Bond hands Kutze a lifesaver just before they jump off the hydrofoil. Presumably he just floated there before being picked up by the Coast Guard.
