When Bond follows Stacey to her home from San Francisco, a radio announcer is discussing the weather. His dialogue is continuous, yet in each shot of Bond and Stacey driving, there is a different background, indicating time-lapse in their journey.
When Bond and Tibbett break into the laboratory, Bond does not even have the basic burglar/spy item of gloves, and leaves his fingerprints all over the lab, being so inept as to "announce" his presence by putting the vial back into the wrong spot.
Bond climbs out of the elevator shaft easily. There is no reason why Stacy can't climb out. Yet, Bond has to come back with a separate rescue for Stacy - using a fire hose as a rope, rather than putting the fire out with it.
The police captain's patrol car is hit by a taxi at a major intersection during the fire truck chase, and five other vehicles swerve to avoid a collision. All come from three directions at once with no signs of yielding to each other, and thus would have crashed or swerved anyway, had the pursuit not blasted through the intersection to stop them.
When James is chasing May Day up the Eiffel Tower, she turns around and whips a fishing line at him, which sends him sprawling over the rail. As he is suspended upside-down halfway over the railing, his legs are spread apart, however when he regains his balance and begins unwinding the fishing line, his legs are now bound together.
In the Golden Gate Bridge scene, the boats consistently change position. First, a wake passes and a small boat is seen on the left most part of the screen for a split second. Two shots later, that same boat is seen entering from the right side. Moments later, a cargo ship is exiting the right side of the screen. Two shots later it is seen entering from the left side.
When Bond is using the fire hose to pull Stacey up from the burning elevator shaft, there is a patch of flames immediately below him which would certainly impede her progress, but when the camera angle switches to show her from his point of view, there are no flames.
The Rolls Royce has blackwall tires. However, after it has been pushed underwater the tires are clearly marked Michelin in bold white letters in the scenes where Bond is using the air in one to breathe.
During the Paris car chase scene, Bond is going in reverse down a small set of stairs, but it cuts to a different camera angle and we see Bond is going reverse down a much larger set of stairs, which appear to be in a different area.
The police car stuck at the top of the drawbridge is a Dodge Diplomat. In the close-up of its rear tire spinning before it falls, the wheel arch is different and is in fact a shot of an earlier Dodge Monaco, which are also used in the scene.
During the fire truck chase scene, the police are driving two Dodge Monacos when they sideswipe each other and lock fenders. A moment later, they hit a post which separates the cars and causes them to spin out of control. When this happens, suddenly the Monacos have turned into Dodge Diplomats. When the police begin the chase again, the cars have turned back into Monacos.
At the drawbridge, with the cop cars having crashed into each other sliding down the raised bridge, the operator makes a move to lower the bridge. But the motion of the counterweight crushing the police captain's car is indicative of the bridge raising, not lowering.
At the first horse race you see that Pegasus is gray. Later at Zorin's stables when they are bringing Pegasus out of a horse trailer, he is brown. Then a few scenes later when they show Pegasus going into a stall he is gray again.
On the main cable of the Golden Gate Bridge, when 007 and Zorin are fighting, they appear to be on a flat platform where the roadway cables would loop around, however in the next shot the roadway cables just loop around the main cable, there is no platform.
When Bond and Sir Godfrey go down the stable elevator to the lab, there is straw on the floor. When the two goons approach the elevator, there isn't any straw. A moment later when they go down the elevator, there is straw again.
When Bond is hanging from the mooring rope of the blimp as he passes over the city, a wide shot shows that it is a cloudy day and the top of the Golden Gate Bridge is covered in fog, way off in the distance. 30 seconds later as the blimp approaches the bridge, almost all of the fog has disappeared and it's now sunny.
Bond attempts to free himself of May Day's wire in the Eiffel Tower. He is seen holding his gun when he goes to reach the wire. In the close-up shot, he is shown freeing himself with both hands and no gun. The next shot has him back holding the gun.
When Bond is chasing May Day up the stairs of the Eiffel Tower, three red lifts go up the shaft within the space of a minute. This is impossible as there is only one lift per shaft, and it takes longer than a minute to go up and come down again. When Bond jumps onto the next lift traveling down, it is yellow, showing they are filming in a different shaft.
When May Day drops a man from Zorin's airship, two buttons can be seen on the wall: first with the upper one she opens the floor, than with the lower one she flats the stairs. After his fall, May Day uses the buttons to revert everything to its original state, however, even though she presses only the upper one, both the floor and the stairs go back to the original position.
When Bond puts the oxygen tank into the turbine, the bottom part of the tank is the part that gets jammed in the fan blade. Notice that the paint is not damaged very much. When Zorin pulls the oxygen tank out of the turbine, the center of the oxygen tank is where it has been cut, and the paint is also badly damaged.
When Bond is swinging from the fire truck ladder as Stacy drives, his feet knock the hats off two guys in a convertible. The driver is on the right side of the car, as though they were in England instead of SF.
As Bond and Stacey are climbing up the elevator shaft, the cables burn through and the elevator falls down the shaft. Elevators have braking systems that prevent them falling even in the event of loss of their supporting cables.
In the Paris chase, Bond drives the front half of a car which apparently still runs. This is impossible even with front wheel drive because the gas tank would be in the back. The brakes would also no longer work because the lines would have been cut.
The type of water intake for the pipeline is incorrect. The blades on the turbine are nearly flat, and thus would not generate any appreciable amount of suction, especially at the low speed is is shown rotating in the film. Additionally, a system dedicated to pumping large volumes of water would use an impeller type of turbine, not the axial type depicted.
The color pattern of the phone box is incorrect for a 25 pair phone line. And the wire position, (IE the 2 wires in the middle of the block) are in the wrong spot. They should be in the far left if they are coming into the block or far right if they are going into the house.
In the horse laboratory with Tibbett, Bond uses a stethoscope to break into the medical cabinet. However, he puts on the stethoscope backwards. This is seen by the angled ear prongs pointing rearwards rather than forwards. In this position the ear pieces do not seal in the ear canals and so no sound can be heard.
Bond's Rolls Royce is shown sinking a long distance from the shore. We then see Bond looking up from under the water and seeing Zorin and Mayday standing on the shore. At such a large angle to the vertical, you can't see anything outside the water: total internal reflection means that the surface of the water from below looks like a silvered mirror. You can only look out of the water through a narrow vertical cone, up to about 60 degrees from the vertical.
When Bond and Stacy exit the burning building, there is a fire ladder leading up to the top floor, even though no firefighters are entering the building that way. Also, the firefighters seem to just stand there on the ground and watch Bond and Stacy make their way down the ladder without trying to help them in any way. It seems as though the ladder was just left there and the survivors are responsible for making their own escape.
When May Day jumps off the Eiffel Tower, she is about halfway up in the tower after being chased up the stairs, but when the jump is viewed from below, it is obviously made from the top of the tower. A special platform made for jumping is clearly visible mounted on top of the Eiffel Tower.
When Bond is fighting Zorin's men in Sutton's mansion at the top of the stairs, the railing is perfectly precut and gives way as Bond pushes the thug past the railing, with only the slightest pressure.
When Bond is talking to Dr. Mortner, the same clip of Bond using the "ring camera" to take a picture is re-used from earlier. You can tell because Bond is not holding a champagne glass at the time he takes the picture, but there is a champagne glass in his hand in the shot.
When Pola Ivanova sneaks out of the Japanese bath-house with the (wrong) tape, she leaves her clothes and underwear behind in a pile; supposedly, she's wearing only a robe. Outside, the robe slips, and briefs are visible.
During the opening sequence, Bond takes a runner from a skidoo and uses it as a snowboard. The trail he leaves behind is from a real snowboard instead of from a skidoo runner, as it leaves a smooth track instead of leaving the mark of a running groove.
After the fight with the intruders, Stacey tells James that the vase contained the ashes of her uncle (it's OK, he always liked a good fight) but when she broke it over the intruder's head, we can see it was empty as no ashes were released.
At the Golden Gate Bridge, Stacey is missing when Bond and Zorin are fighting, there are inconsistencies in the ships sailing underneath and then when Stacey and Bond are together at the end, the fire axe has disappeared.
When the mine is flooded and May Day and 007 are caught in the water, May Day's hair is completely drenched and ruined. She even has to push the damp bangs from her eyes. Later, when she and James are discussing what they should do about the bomb in the power keg, her hair is perfect again, despite James' shirt still being wet and plastered to him.
When Zorin falls from the blimp, he and Bond are wrestling at the top of one of the Golden Gate Bridge Towers. However, they immediately cut to a shot where he's falling off the road deck of the the bridge.
