Other mistake: In the plane when Bond fights Goldfinger, one of the henchmen is partially visible behind Goldfinger when he appears from behind the curtain. When the fight starts, the henchman's arm is also visible. When the fight is over and just before Bond moves to the cockpit, the henchman is lying on the floor with no explanation for why he was not sucked from the plane like Goldfinger.
Other mistake: The crushed 'cube' car is not the whole Lincoln; that kind of small cube is produced in junkyards from the body only, without wheels, drive train, etc.
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.
Other mistake: After Goldfinger has lost the golf round and is about to depart, Bond hands Oddjob the Slazenger 7 and says 'I believe this is yours'. Oddjob (who's obviously upset that Goldfinger lost) crushes the golf ball and throws it out the window. It's ridiculous. 1: Golf balls have a liquid or rubber core, so you'd see the residue. 2: A golf ball has several very hard layers to prevent it from collapsing on a hard impact. 3: When Oddjob throws it, look closely and it looks a bit like a section of a styrofoam cup.
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: 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.
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)
Other mistake: In Fort Knox, where Bond has just gotten un-handcuffed from the bomb and is battling it out with Oddjob, Bond throws a gold bar quite a horizontal distance and hits Oddjob in the chest. The fact that it bounces off is in keeping with the fantasy of Oddjob's strength - but how in the world did Bond throw it that far? A Fort Knox gold bar weighs over 27 pounds.
Other mistake: When several cars are pursuing Bond and Ms. Masterson through the woods, the first car falls prey to the smoke screen. As the second car continues pursuit, a man leans out of its passenger window to shoot at Bond. But he doesn't appear to be aiming, or even holding his gun tightly; the muzzle waves far to one side for the first several shots.
