Revealing mistake: When Bond and Melina are being chased in Melina's car, they are rolling upside down in a street of a small village. With help of some other people they tilt back the car on his wheels. At that moment you can see specially added roll bars mounted in the car to prevent the roof from crushing.Vince van Riet
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.
Revealing mistake: During the fight with Bond and the ice hockey players at the ice rink, Bond climbs into the Zamboni and "hits" the last hockey player, sending him into the net with the other two players. When you look closely at the footage, it appears the hockey player literally skates head-on into the Zamboni on purpose.
Revealing mistake: When Bond reaches the top of the cliff, Apostis kicks him in the face. You can see that Apostis' boot never makes contact with Bond's face, but Bond reacts as if it did.
Revealing mistake: When Bond pushes Kriegler through a window, we can see in the shot of Kriegler falling that he is just a dummy.
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.Doc
Revealing mistake: When "Mac" is told by the captain of St. George's to destruct the ATAC system, an explosion occurs and he gets thrown to the ground. When this happens, you can see that the man playing Mac is his stunt double.
Revealing mistake: Many of the underwater close up shots are done with a fish tank in front of the camera and bubbles superimposed where the actors' breathing apparatus should be, but the location of the bubbles isn't always correct. This is obvious in the first underwater diving scene at the archaeological dig with Bond and Melina. In some shots the bubbles appear to come from her hand instead of her regulator. The position of her hand matches the location of the regulator in close ups of Bond. (01:21:10)riku2
Revealing mistake: When Bond enters Q branch, he is met by a technician with a false broken right arm. After saying "Coming along very nicely sir" the arm then swings to the technicians' right breaking the head of the dummy. This then reveals the arm of the technician, who then holds his hands suggesting the false arm is a 'Spy Gadget'. You can see that the revealed hand is not that of the actor but of someone stood behind the set wall. The actor has used his real arm to carry out the effect, and then clasped the hand of the extra person. This is supported by the fact the arm movement can be seen through the shirt, the skin complexion of the hand is completely different to the actor, the arm looks like he is being hugged, when he puts his hands together it is not natural, and as they move away he moves his right shoulder up and the 'third' arm remains in place.John Hancocks
Revealing mistake: When Bond attacks the ice hockey player in yellow with his stick during the fight at the hockey rink, you can see the player reacts to being hit just before the stick makes contact.
