Continuity mistake: In the first shots of the golf course, you see Goldfinger's Rolls parked to the far left of the main building, with Bond's car in the lot in the background. When the scene changes to the inside of the clubhouse store, the Rolls is now very close to the front of the store. At the end of the golf game, the Rolls is back to the left of the main building, and as the camera pans back, you can see that the store is to the far right of the main building.
Continuity mistake: Right at the end, the insurance man gives Charlotte Jewel Mayhew's letter and in the next shot of him, his hands are empty. But in the following shot he's holding the letter again.
Revealing mistake: When Marnie is dreaming, watch her window. The curtains move as if there is wind, but the window is closed.
Continuity mistake: In the train yard scene when Le Biche and Colonel Von Windheim are watching for the trains to switch to the right tracks a pipe is tossed onto a chair and tobacco spills out, but when the camera is panned away and comes back the tobacco is nowhere to be seen.
Factual error: When the pursuing fighter jets are supposed to start their engine afterburners, we instead see a short clip of them firing their air-to-air missiles.
Factual error: The movie shows a 'jet' aircraft belonging to 'consolidated airlines'. The so called airplane is a laugh. It has two jet engines attached to the horizontal stabilizers. The landing gear appear to be bolted to the wings. During the movie this plane crashes and the engines are moved to a terminal to be examined. They are too small to be real engines. During the course of examining the engines, they are run inside the terminal building. One of the investigators stands 10 feet behind the jet intake and is not sucked inside. The cockpit is not even close to what one would find in a jet airplane.
Visible crew/equipment: The shadow of a camera and cameraman are revealed on the left side while the President (Frederic March) is moving from one room to another (door jamb), after learning about Martin Balsam's death. (01:20:00 - 01:21:00)
