Continuity mistake: After the game of golf between Goldfinger and Bond, Goldfinger gets Oddjob to show off his usually dangerous hat. He throws the hat at the statue and we see it fly off to the right of the screen, well away from the statue. Yet in the following shot, the decapitated head falls down next to the hat on the ground right by the statue.
Continuity mistake: Oddjob drives a '64 Lincoln into the junkyard. Then he walks away from a '63 Lincoln, which is the car that is crushed. (01:13:15 - 01:15:25)
Revealing mistake: When headshots are shown of Bond inside the Aston Martin at the Auric Factory, and when he drops Tilly off at the gas station, you can see the three holes left in the headliner of the car where they have removed screws for the interior sun visor. (00:37:50)
Visible crew/equipment: During the scene at the golf club, when the Rolls Royce begins to move off, the reflection from one of the film set lights can be seen on the rear left hand side of the Rolls Royce: There is no way that this could have been the relection from the sun, because the weather during the scene was on the dull side. (00:31:50)
Factual error: When Tilly Masterson's Mustang crashes, the laws of physics are ignored. Tilly does not go through the windscreen and is not hurt at all, despite the high rate of speed and sudden stop. (00:36:15)
Continuity mistake: The Aston has a dent in the side that comes and goes between scenes.
Revealing mistake: When Bond's car crashes at the Auric factory, and the Mercedes comes to a stop, you can see the cut edges of the colored paper covering the headlights of the Mercedes. (00:45:50)
Deliberate mistake: When we first encounter Tilly Masterson, she overtakes Bond and he decides not to pursue her. Then, when Goldfinger has stopped, Bond is actually ahead of her as she nearly hits him with a rifle shot. Given that most Swiss passes are single carriageways, surely Bond would have noticed her had she parked earlier. (00:33:30)
Continuity mistake: After Oddjob has knocked Bond out whilst he was looking for some cold champagne, Bond is seen lying in front of an open refrigerator door which has five small and one large bottle on the lower shelf. When Bond awakes there are now six small and one large bottles there. (00:15:35)
Continuity mistake: When Oddjob drives Mr. Solo to the airport, he drives him in a black car. After he shoots him and takes him to the scrap yard, then he has the car crushed in the compactor. When it comes out, it's the compacted remains of a car painted a lighter shade of blue.
Other mistake: Pussy Galore's flying circus is approaching Fort Knox flying in a V-shaped formation. Pussy is counting down from 5 to 0 before they release the nerve gas. On each count, we see another female pilot in a different plane but we also see another plane through the right side window. If you fly with 5 planes in such formation, only 3 planes can have another plane at their right side, not 4 or 5.
Factual error: When the Flying Circus is on it's way to Ft Knox, the lead pilot reports they are proceeding at 240 knots. Top speed on a Piper Cherokee 180 (the plane in question) is/was 141 knots.
