Factual error: When Goldfinger's pilots fly over Fort Knox to deliver the sleeping gas, they could not have done this in real life because Fort Knox is in a no fly zone. Fort Knox's airspace is a 3.5-mile radius and it goes up to 3,500 feet. They'd have been intercepted in no time. (01:29:06)
Revealing mistake: When Bond is at the hotel at Miami, in several scenes you can see that film was shot at a hotel, and then the editors placed the card game opponent's figure in the film. The filming of the figures is a lot clearer and crisper, while the background looks like a homemade film.
Continuity mistake: After we first see Tilly Masterson's car overtaking Bond's Aston, the next few shots of the scenery are inconsistent. What is seen through Bond's car windows does not match the scenery in the subsequent long shots. And Tilly's car is shown leaving the village, then after getting out on the open road, the shot through her rear window shows her leaving the village again.
Factual error: Due to the actual weight of gold, it would be inconceviabe for the gold to be stacked in such a way as it is depicted in Fort Knox.
Factual error: When Odd Job gets electrocuted at the end, the electricity would only go through his body if he were grounded, which he wasn't. So only his hand would really have gotten shocked.
Continuity mistake: When Oddjob drives into the junkyard, watch his shadow as he exits the car. Then look at the shadows while he drives off. Some hours have passed between the shootings, perhaps the missing hours are the ones it took for the engine to be removed from the car? (Check the other mistake from this scene).
Audio problem: When Bond fights Oddjob in Fort Knox, he tries to hit Oddjob with a metal pole, but it ends up to wall, and Oddjob cuts it with his hand. The remaining piece of pole falls to floor and it sounds like the pole is made of styrox.
Other mistake: When Q briefs Bond about the Aston Martin, he tells him the homer (tracker) has a range of 150 miles. When Bond is tracking Goldfinger in Switzerland, he is momentarily distracted while Tilly overtakes him. The blip on the screen has then disappeared, meaning G's car is some 150 miles ahead. But moments later, Bond pulls up on the hillside above where G has stopped for refreshments. How could he have made up the best part of 150 miles in so short a time?
Other mistake: Inside the plane Bond punches Goldfinger's chest. However, Goldfinger reacts as if he had been punched in the face.
Continuity mistake: Bond is in bed with Jill. He goes to get some ice and she faces forward at him. A shot later she is facing upwards and her head is tilted sideways.
Continuity mistake: When Oddjob throws his steel-rimmed hat to kill Tilly, you can see the hat falling in a downwards direction, yet it still manages to hit Tilly on her neck.
Other mistake: In the scene where the flying circus pilots are introduced and are landing, you can plainly see that one of the pilots is a man with a cowboy hat on, rather than one of the girls.
Plot hole: When Bond goes into the kitchen for the champagne, Oddjob is waiting for him. But where was he hiding? Oddjob couldn't have hidden in the bedroom without being seen. The kitchen is separated from the bedroom about halfway by a metal grate and not a wall. Oddjob could have only been hiding in front of the cupboards since we can see Bond from the bedroom POV all the way to the refrigerator. There is no possible way Bond wouldn't have seen him or even brushed against him. There is lighting in the kitchen, which we know because Bond is illuminated when he walks in; he casts a strong shadow on the floor during and after his fall (not from the refrigerator); and is illuminated when he stumbles out. The pan shots of the kitchen show no places where Oddjob could have concealed himself - and he is not exactly on the thin side.
Suggested correction: But he is on the short side. Bond just didn't look down.
Continuity mistake: When drinking with Bond, Goldfinger's julep alternates between being in his hand and on the table, between shots.
Continuity mistake: When Bond is picking a bottle from the fridge and is knocked down by Oddjob, he lies with both arms extended, yet the left one moves down between shots.
Continuity mistake: In Fort Knox, Bond throws Oddjob's hat and gets it tucked between the metal bars. A frame later, the hat is tucked further in between the bars.
Continuity mistake: After Bond speaks with Felix on the phone, the escort is lying on the bed looking at Bond, her hair all around her left cheek. In the next shot it's brushed backwards.
Revealing mistake: "Q" says Bond has to activate the homing device by pressing it, but he doesn't press it, he pulls it back.
Deliberate mistake: When Bond interferes with Goldfinger's cheating at cards in Miami Beach, we are watching the shot in which Goldfinger snaps his pencil and hits the table with his fist through binoculars from Bond's position far away on the hotel balcony. The sound of Goldfinger's actions are audible making the scene more effective. However, Bond and therefore the viewer wouldn't actually be able to hear it. (00:13:20)
Other mistake: Right at the end of the golf match when Bond is about to make his final shot, you can see two shadows being cast onto the lawn. Since the only source of light in this scene is supposed to be the sun, there should only be one shadow. The second one is caused by the set light. (00:29:35)
