Continuity mistake: Near the end when Kristatos slaps Bibi, you can see the difference between two takes.

Continuity mistake: When Melina's car is hit by the machine gun, we see a close-up of the back end of the car, including the 2CV6 sign. Later in the car chase there suddenly is a Spanish national sticker (E) to the left of the 2CV6 sign. The bullet holes are different as well.
Continuity mistake: When Gonzales opens the suitcase with money the middle pile is taller than the others, and is more than one bundle of notes taller than the rim of the suitcase. In the next clip, when Gonzales grabs one of the bundles, the middle pile is no taller than the others or than the rim of the suitcase.
Continuity mistake: The bullet holes in the back of Melina's car change pattern and size several times during the car chase.
Continuity mistake: In the casino scene, when Bunky makes his first bet, his two remaining piles of chips are totally straight. When he reaches for his cards, they are not.
Visible crew/equipment: Right after 007 can escape by jumping from the ski tower, Christatos gets into his car. When the car drives away you can see clearly a part of the filming crew including a set of lights in the windows reflecting.
Plot hole: As we first see the St Georges, a marine officer in uniform is seen smoking on deck. On the other hand, we have camouflaged doors, fishing going on, everything consistent with a completely secretive operation. It is not very consistent, nor does it make much sense to put that much effort into hiding the true nature of the ship and then go gallivanting across deck in a navy uniform.
Suggested correction: He is not in uniform.
Continuity mistake: During the car chase in Spain, we see a close up of the crumpled radiator on Melina's 2CV, and one of the black cars is directly behind the car at this point. But in the next shot when the 2CV goes around a corner, the black car is much further away than it was in the previous shot. (Widescreen version.)
Revealing mistake: When Bond and Melina are attacked by the JIM suit diver whilst looking for the ATAC system in the wreck of the St. George's, the diver pulls Melina up and you can see the cable and hook on the back of Melina's diving suit winching her up the wall.
Other mistake: In the casino scene they're playing Baccarat. Bunky reveals a natural 8 (5 and 3). When Bond's hand is revealed, the croupier announces 9 for the win: "et neuf la banque" ("and 9 for the bank"). Only, Bond has revealed a Queen and a 5 (a natural 5).
Other mistake: When Bond is being chased on the bobsled track, just before he escapes the track.there is a shot of Eric Kriegler taking one last shot at him. In this shot however, Kriegler's bike appears to be in an open area and certainly not on a bobsled track. In fact it looks like a disused shot from when the chase started.
Continuity mistake: At the restaurant, when Colombo rewinds the tape in the lamp it passes over 2-3 sentences and then he plays the tape starting with the sentence 'But I must warn you.' But after that Bond and Kristatos exchanged 18 sentences, which lasts for approximately a minute before the lamp is removed from the table. Colombo did not rewind the tape that far.
Continuity mistake: In the opening scene with the helicopter, when we first see Blofeld there is a tall wall to the front left of him. But when we see him in the overhead shot and when Bond flies close by him, there is no such wall.
Revealing mistake: When Locque's Mercedes starts to slide off the cliff at the end of the car chase you can see cables holding it up.
Continuity mistake: When Bond and the countess start walking on the beach (and we see some divers jump in the water from a Zodiac) the water is totally calm. Not a wave in sight. But when Locke comes in the dune buggy, and we see an overhead shot, there are quite large waves.
Continuity mistake: Right before Bond gets on the bobsled ramp, he puts one of his ski poles between two trees, leaving him with no ski poles (the other one was shot by the skiing expert). As Bond jumps onto the bobsled ramp, there is a quick shot with Bond holding one ski pole and after another quick shot, when Bond is on the ramp, the pole is gone.
Other mistake: General Gogol's helicopter has Polish civilian markings, SP-(3 letters), repainted so they would resemble Soviet ones. However, Soviet markings were CCCP-(5 digits). When Gogol comes out of the helicopter, the manufacturer's logo (PZL-&346;widnik) is visible over his shoulder.
Continuity mistake: When Melina is going to see her killed parents, they don't have blood on them but the shot later, her father has blood everywhere.
Revealing mistake: Bond kills Locque by pushing him over a cliff in the Mercedes. When the wrecked car finally comes to a halt upside down at the bottom of the cliff you can see that the running gear and engine of the Mercedes have been removed and the wheels are simply held on with 2 straight beams (it is a different car altogether, just a shell with wheels).
Continuity mistake: The damage to the yellow Citröen 2CV appears / disappears between shots, especially after exiting the village and rolling down a hill. For example both of the headlights get knocked out, then the reflector reappears shortly afterwards.
