Continuity mistake: When Bond turns in the opening scene to fire his ski pole he turns left, then a split second later he turns right. No way at that speed anyone could turn left then right without falling. (00:02:00)
Continuity mistake: When Bond hangs the clear sheet on the screen, the dark line is both next to and on top of the pink line showing the submarine course. A moment later, the clear sheet has moved, making the lines further apart. (00:13:58 - 00:14:41)
Suggested correction: The pink line is always visible and depending on the camera angle it's brighter in places than others, if the clear sheet with the black line on has moved it's very slight.
The mistake says nothing about the pink line not being visible or changing brightness. And if the clear sheet moved slightly, that's a mistake.
Continuity mistake: When Bond goes to check Fekkish's bedroom the top button of his coat is buttoned. He goes to the door, looks in, and comes back out with the button unbuttoned, without unbuttoning it. (00:24:50)
Revealing mistake: When Bond is in Fekkish's home and the woman that meets him gets shot after he spins her around, his gun appears already in his hand and he fires it. He never reaches into his holster to get it. (00:25:55)
Revealing mistake: As Bond enters the night club in Egypt, the camera pans right to reveal two extras who appear to be waiting for their cue to start walking, but obviously miss this cue as they don't actually start walking until the camera is on them. (00:32:48)
Audio problem: When Bond and XXX are following Jaws in the ruins, we hear his footsteps when he walks but not theirs when they run on the same concrete floor. (00:40:55)
Factual error: When the two missiles blast out of the water, the first thing you see is the glare of the rocket motors under water. SLBMs rise out of the water solely on the air or steam pressure impulse that propels them out of the launcher. The rocket motors ignite only after the missile has left the water completely. (01:43:20)
Factual error: As the SLBMs eject from the submarines, they visibly jostle and shake the missile tube hatch, especially the second one - the hatch even scrapes the missile surface. Real missile hatches don't do that. In fact, if the missile actually did scrape the hatch, both the hatch and the missile would be irreparably damaged - consider the momentum of a 10m high, 13 ton missile... (01:43:20)
Revealing mistake: The shot of the two nuclear missiles being launched is used twice, just reversed. They seem to have changed the saturation slightly in one of them to make it look different, but there are identical clouds at the top left/top right in both shots, ruining the trick.
Continuity mistake: On the train, the wine stain on Jaws' jacket disappears for one shot and then reappears. It then changes size and shape repeatedly.
Plot hole: If they assembled the wet bike on the submarine, they wouldn't be able to get it off as it would be too big to fit through the hatch.
Plot hole: When Bond's Lotus is being attacked while it's traveling underwater, it develops a few small leaks, which spray a thin stream of water into the car. When the Lotus drives out onto the beach, Bond rolls down the window and drops a big fish out of the car. How did that get in there? If there was a hole in the car the size of that fish, it would have flooded the driver's compartment and sunk the car.
Continuity mistake: When 007 pushes Jaws outside the train, he breaks the window, but it is intact in the following shot. It's broken again a little bit later.
Factual error: When James Bond programs the two submarines to destroy each other, we see the paths of the missiles displayed on a globe. They swing across in two arcs, narrowly missing each other. However, we are looking down on the surface of the globe with no height perception, so the missiles should, in fact, travel in straight lines directly between the submarines.
Continuity mistake: In the scene where Stromberg is thanking Dr. Bechman and Professor Marcovitz, he has a towel in his hand. When the camera changes to another angle that shows the back of his chair, his hands are totally empty and resting on an arm of the chair. Then it changes back to the original camera angle, and he now has a towel in his hands again.
Deliberate mistake: As the Lotus drives off the pier and enters the water, the exposed underbody is that of a normal car. After it enters the sea, the underbody we see is completely sealed, which it needs to be to allow the car to submerge.
Factual error: When Jaws kills the shark, the carcass floats on the surface of the water in the tank. It should sink to the bottom, as dead sharks do.
Continuity mistake: When Q is showing the microfilm to Bond and XXX, Bond points at the Stromberg fish. But he points right at the projector. That would have made his finger much larger compared to the screen than it is in the next clip - and blurred. Furthermore, the position of his finger on the screen doesn't match with the position he holds it in.
Plot hole: When the submarine with Bond aboard sees the Liparus it is 6,200 yards away, and over to the side. How can it then suddenly be behind the submarine?
Continuity mistake: When Bond skis downhill in the beginning, in the close-up of his skis, you can see a hard, firm snow surface. But in the next clip, he is skiing off-piste.
