Continuity mistake: In the scene where Stromberg is thanking Dr Bechman and Professor Marcovitz he 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.
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.
Continuity mistake: When the rescue pod is speeding towards the surface you can see it has a keel weight which, judging from the size of the pod, must be 3-4 meters long. When it floats into the cargo bay of the navy ship, there wouldn't be room for the keel. You can see that the water level in the cargo bay is no more than 1-1½ meters.
Continuity mistake: At the end of the film we see the large tanker ship exploding at many different areas of its hull including a lot of explosions on the topside. However, there is a point where the camera shows the ship sinking with an underwater shot, sinking with bow first and then progressing towards the stern and there are no holes let alone burn marks that would show where the explosions took place.
Continuity mistake: When Stromberg raises his 'house' from the sea, in the first shot where the paintings slide up, you can see the water's surface in the top of the window. But in the next clip, exterior shot, the house is still fully submerged. And based on the size of the house and the location of Stromberg's living room, his windows must have been 10-20 meters below the surface in the first situation.
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)
Continuity mistake: When Bond places the OHP film on the tracker, it perfectly matches the line of the course, whereas when Q arrives on the scene, the line of the tracker deviates.
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)
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: At the submarine base Bond places a see through copy of the submarine course on the display and the two lines match up and are touching, in the next shot the bottom of the lines are no where near each other but meet further up in the middle.
