Continuity mistake: It is 1940. Two pilots come out of a house - one of them has just lost his wife and family in the London Blitz, the other is an RAF Squadron Leader. The door they come out of has a modern electric bell push - a post 1965 version, white rectangular box with a round button.
Continuity mistake: After the gang is pulled off the bank job, they race away in the three Minis - as they go through a tunnel at one point they roll up and down the sides of the tunnel. The mistake is that each car supposedly has two occupants, but on one shot of the cars in the tunnel, one car has only a single occupant - visible because the car following has his headlights on illuminating the car in front.
Continuity mistake: When Blofeld gets thrown from the bobsleigh and gets his neck caught between the branches of a tree, he is caught under his arms in the long-distance shot.
Continuity mistake: Sykes is shot in the right leg, in the thigh area, by the bounty hunters. We see the blood clearly on it when he sits on a rock and holds his leg. Later, when he returns to Aquaverde where he meets Robert Ryan, we see as he sits on his horse that his left leg is bandaged.
Continuity mistake: In this scene we see the General briefing his men. A map is spread out over the bonnet of a jeep. While he is studying the map and planning the next move a steaming hot cup of something is given to the General and is placed on the map for him. The General then takes it in his right hand and is about to drink it when someone speaks to him. The General replies to him and in the next wide angle shot there is no cup in his hand nor is it anywhere else.
