Revealing mistake: When Bond and XXX are visiting Stromberg's home by speed boat it shifts or rocks in the water when they step on board. This is normal, because speed boats are very unstable. When they reach Stromberg, they have to step off, but the boat does not shift in the water as it should, in fact, the way the boat slowed and stopped was stiff and unnatural. Obviously indicating the boat was on a trailer for these scenes.Vince van Riet
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 XXX is freed by 007 to escape the torpedoed base she is wearing a red bikini. As the escape develops this changes to black.
Other mistake: When the captain of Stromberg One tells missile control they have a change of target he reads a new set of coordinates (which is really Stromberg Two). But if you look at the paper that was just printed the coordinates he reads are not on the paper.
Other mistake: Just after Naomi winks at Bond the helicopter turns to the left. The same piece of film is used again just as Bond drives onto the jetty.
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)
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.
Continuity mistake: When Bond is waiting to meet Stromberg he notices the remains of the women killed at the beginning by the shark, but the tank with the shark in has nothing in it but water and the shark. The tank Bond is looking at has coral and other fish in it.
Revealing mistake: During the helicopter/Lotus chase the shots of the helicopter turning are used twice.
Deliberate mistake: When the speedboat docks at the Stormberg Laboratory with Bond on board the speedboat has no helm or gauges fitted to the dashboard. From that angle we should see them or something resembling them as we did when Bond was picked up.
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)Doc
