Continuity mistake: Just after Loque runs over the countess in his dune buggy, Bond runs over to her, kneels beside her and takes her pulse. She blinks.
Factual error: In the pre-credit sequence with Bond and Blofeld, the helicopter makes a steep dive, however, the sound it makes is for a fixed-wing airplane, similar to dive bombers in WW2. Helicopters make no such sound.
Continuity mistake: During the fight at the ice rink, one of the ice hockey players tries to kick Bond with his blade and makes a hole in the wall in the process. In the next shot, when another player tries to hit Bond with his ice hockey stick, the damage to the wall has suddenly disappeared.
Continuity mistake: The ski jump in Cortina d'Ampezzo is in the bottom of the valley - which can also be seen in the overhead shot from the top of the ski jump. But nevertheless Bond has a long ski ride down from the bottom of the jump. And in several shots during the chase it is clear that he is much higher in the mountains than below the city.
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.
Revealing mistake: When Bond throws the dead pilot out of the helicopter, you can tell it's a dummy as its arms and legs bend at impossible angles.
Revealing mistake: At the end, where Bond receives the "Come in 007" message on his watch, one can see that the watch has been filmed separately to the wrist: the wrist moves slightly , but the watch itself remains perfectly still.
Continuity mistake: During the car chase in Spain, when one of the two black cars bump into Melina's 2CV, we see a close up of the driver and there no vehicles visible on the road behind him. In the next shot when the 2CV is pushed off the road, the second black car is almost directly behind him.
Continuity mistake: When Bond and Melina are being chased in Melina's car, after they roll down the hill and hit the road, the tires actually bend under the car. Then when they drive again, they are straight.
Visible crew/equipment: At the end when Max the parrot drops Bond's watch into the water you can see a piece of wire lowering it in.
Continuity mistake: In the scene where Locque is kicked off the cliff by Bond in his car, it is a Mercedes-Benz S-Class, model W 116. But in the shot before, when Locque drives away from Kristatos' warehouse it is the predecessor of that model.
Revealing mistake: When Bond and Melina are pursued by Gonzales' henchmen in Madrid, we see a close-up of one of the cars and the man in the back seat begins shooting at them. If you look carefully, you can see there is no-one in the front seat.
Continuity mistake: Bond fixes the end of his rope with a spring-loaded camming device (which is unsuitable for lose, porous rock by the way). When Apostis tries to dislodge him, the end loop of the rope is fixed to a piton - it has to be, because SLCDs literally cannot be knocked out of the rock.
Revealing mistake: As Bond prepares to drop Blofeld into the smoke stack, you can see that the cervical collar isn't put on correctly, the actor can still move his head. The intention of a cervical collar is to take all strain off the spine and neck muscles and prevent any movement that could cause damage to the spinal cord. To work, a stiff neck must be fixed so the neck is completely immobilized and slightly extended. However, wearing a cervical collar is very uncomfortable to the wearer, so they probably used a slightly lower one and didn't fully tighten it.
