Continuity mistake: The first time we see Goldfinger by the pool, in the wide angle there's a girl with an orange bathing suit, and a man with a striped shirt next to her. In the close-up, the man now has a white T-shirt with a blue print, and the girl has a white bikini and an orange skirt.
Continuity mistake: By the pool, Bond is given a note by an agent. The way he holds the note changes between shots.
Continuity mistake: During the pre-credits, the amount of soap on the back of the girl that was taking a bath changes between shots.
Continuity mistake: During the pre-credits, Bond lights his lighter to check his watch before the explosion. In the close-up he lights it again.
Continuity mistake: During the pre-credits Bond enters a room and his hands are spotless. In the close-ups of him placing explosives they're very dirty.
Continuity mistake: When the head of the statue falls on the ground after being decapitated by Oddjob's bowler hat, the head is now bright white and no longer matches the colour of the original marble.
Continuity mistake: When Colonel Smithers says "That's not quite fair" during the dinner sequence with Bond and M, the position of Smithers' hand/cigar jumps between shots.
Continuity mistake: When Bond is knocked unconscious by Oddjob in Goldfinger's suite, the robe-knot on his dressing gown changes when he regains consciousness.
Continuity mistake: As the vault door closes the shadow of the running man can be seen at the door, which was still open enough to get through. Inside the vault, he just reaches it as it shuts.
Continuity mistake: When Bond gets in the car outside the hangar in Kentucky, we see Oddjob open his door to get in. In the close up of Bond in the next shot, however, we see the car door is now closed, but we still hear it closing in the shot.
Continuity mistake: When Bond and Oddjob are fighting to the death at Fort Knox, Bond retrieves Oddjob's lethal steel-brimmed derby hat and takes aim, preparing for a backhand throw with his left hand. Camera cuts to a startled Oddjob for a split-second. When the camera cuts back to Bond, he is executing a much more difficult forehand throw with his right hand.
Continuity mistake: When the cube of metal that was the Lincoln comes out, the electromagnet comes in and grabs it as it sits close to the exit. When the camera cuts to a wider shot, the cube is being lifted from a further distance out from the exit.
Continuity mistake: After Shirley Eaton is painted gold, Bond looks at her legs. The shot shows a pair of short, heavyset legs. These are a stand-in's legs or artificial ones. Shirley's were long and perfectly shaped, as seen at the beginning of the bedroom scene.
Continuity mistake: In Goldfinger's plane, Bond's Martini swaps from being by his lips to down by his waist.
Continuity mistake: In Fort Knox, after Oddjob cuts the cables, his hat and the cable change positions on the floor.

Continuity mistake: In the barn, after being flipped over, Bond's hair swaps from messy to brushed between shots.
Continuity mistake: In the opening, Bond finds the button to let open the secret hatch in the oil tank. This hatch looks very heavy and is driven by a motor or something; you can hear the humming sound of it as well. When Bond is inside, now he can close it by hand. Also when he leaves the oil tank, he uses the same hatch, and can now open and close the hatch again with his hands.
Continuity mistake: At the card game in Miami, before Goldfinger joins his opponent at table, the card backs are blue, but when he sits down and they begin the game, the card backs are red.
Chosen answer: They're not. Q was just indicating to Bond that these were the wing machine guns, he wasn't stating which was which.
