Factual error: When Bond is flying from Europe to Baltimore on his way to Goldfinger's studfarm in Kentucky, Pussy states that they are flying at 35,000 feet. Flying west, they would fly at an even altitude, not odd.
Factual error: Goldfinger says his Rolls is made from gold, but the magnetic homing device clings to it. You can't attach a magnet to gold.
Plot hole: Goldfinger wasn't planning on Mr. Solo breaking away from the rest of the gangsters before Goldfinger could have them all killed by the nerve gas so it makes no sense that there would already be a truck from the stud farm waiting for Oddjob to drive back with the remains of the crushed car. It also begs the question if Oddjob had to drive the truck back to the farm where is the guy that drove it to the junkyard in the first place?
Revealing mistake: The rear projection behind Bond as he is driving through Geneva doesn't match the scenery outside his car.
Continuity mistake: Near the start when Bond and Moneypenny are talking about gold, she throws his hat at the hatstand. The top of the hat is facing left as it flies offscreen, but when the shot cuts to it landing it's turned itself around so it can catch properly on the hook. Plus it lands on the hook furthest from the door, but when Bond leaves he picks it up from a closer hook.
Continuity mistake: When Bond comes around on the plane and meets Pussy for the first time, she tells him they are flying SW over Newfoundland. The clock on the restroom door shows 10.05am. Later, when she announces arrival in Baltimore in 55 mins, the clock is now showing 2 .45pm giving arrival time of 3.40pm. Flying time would have been approx 3 hours, arriving at 1.05 pm.
Revealing mistake: Before Goldfinger is sucked out of the plane, the flying cushions (superimposed on a chroma) magically vanish.
Revealing mistake: When Oddjob is killed and falls face-down, he turns his head to the left a second before he smashes it against the floor.
Continuity mistake: When Oddjob arrives at the junkyard, it's a cloudy day and the car casts no shadow; however, a shot later, from a different angle, it's a sunny day and there's an 8 o'clock shadow beneath the car.
Continuity mistake: After Bond hits Oddjob with the stick, Oddjob launches him face-down, but from the next angle Bond is landing and sliding face-up.
Revealing mistake: When Bond grabs a huge stick to attack Oddjob, the first wide shot behind Bond is of a very obvious stuntman with a square face and a prominent jaw. Stunt also visible after Bond jumps and grabs Oddjob's neck, when he is launched against the wall.
Revealing mistake: When Oddjob throws his hat at the statue and the head comes off the head falls on top of the arm and breaks it. Obviously this was not meant to happen as there is a quick edit in the film before the arm falls completely off (notice the trees behind the statue suddenly freeze).
Revealing mistake: When the CIA guys are following Odd Job to the airport in "Kentucky" there are several indicators that show they are in Florida. One is a big sign that says Opa Locka, which is north Miami.
Character mistake: Goldfinger is holding a S&W .38 in his plane. Bond says (in his explanation about shooting guns in planes), "That's a Smith and Wesson .45."
Other mistake: At the 17th hole, on his "drive" shot, Goldfinger actually hits a straight drive that never leaves the ground. (00:28:01)
Audio problem: Bond's tires squeal as he brakes hard on the gravel/dirt road during the car chase in the woods near the factory.
Suggested correction: Yep, happens all the time, depending on how firm the road is.
Revealing mistake: Bond's unconscious body falling out of the car at the end of the car chase is obviously sped up.
Continuity mistake: After Bond has wrecked Tilly Masterson's car, he takes her to a gas station. At the gas station, there is a orange camping tent visible in the background, When Bond leaves the gas station, the tent is suddenly gone.
Factual error: According to Bond's radar map, Goldfinger is driving north of Geneva. There aren't any mountain passes north of Geneva. The whole sequence (involving the murder attempt by Tilly) was filmed between the Furka Pass and the town of Andermatt.
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)
