When Bond is getting a rubdown from Dink, his back is perfectly shaved. When he wakes up the next morning with Jill, he has apparently grown a good deal of back hair.
After Bond ejects Goldfinger's henchman at the factory, subsequent shots of the Aston Martin show the roof sections intact.
When the Lincoln is being lifted into the crusher, the car tilts, and it is obvious that there is nothing i.e. no body in the back seat.
Goldfinger's crew uses a giant truck-mounted laser to burn their way through the Fort Knox entrance. Several shots of the truck show the laser beam being moved across the entrance extremely rapidly; however, when these shots are intercut with views of the entrance itself, the beam inches across the entrance door very, very slowly.
After the soldiers are all knocked out by nerve gas, the procession to the gold depository is led by an army jeep. The jeep shown keeps switching back and forth from a WW2 era jeep to a much later 1950s-style jeep. The trucks also change between shots.
There is nothing about decompression that changes the aerodynamics of aircraft. Wings still produce lift and the control surfaces still function. Remember Aloha 243 landed safely with a third of its upper fuselage missing.
In addition to what has been pointed out by others about the small Ford Falcon-based Ranchero truck never being able to carry the crushed Lincoln Continental (weight doesn't change because something is compacted to a smaller physical size), the Continental's large-block cast iron engine (which is fairly non-compressible)is almost as large as the depicted "cube" by itself let alone all the rest of the car's parts. Even today, there is no way a vehicle of that size can be turned into a compacted cube of the small size that was depicted, let alone with crushing equipment from 50 years ago.
The 1964 Ford Ranchero that Oddjob uses to carry the crushed continental could carry a maximum load of 800 pounds. Depending on options, the curb weight of a 1964 Lincoln Continental is between 5,000 and 5,700 pounds, with an average weight of 5,350 pounds. In 1964 $1 million in gold bullion weighed 974 pounds, raising the car's weight to 6,324 pounds. Add one passenger (or corpse) and this comes to about 6,500 or three and a half tons). That comes to 8.125 times the maximum load of the Ranchero.
The idea that all-over gold paint would suffocate someone is something Ian Fleming made up.
In the Fort Knox vault, the gold is stacked too high to be practical. Given the weight and softness of gold, the lower bars of the stacks would be flattened by the sheer weight of the bars above them.
While Bond is giving Tilly a lift to the garage, he looks in his rear view mirror at the initials on her case. He sees "T.M." His view should be ".M.T" This is because we don't see a camera shot of the mirror. The camera shows the case in the back, so the initials are not mirrored.
Felix allowed Goldfinger's henchmen to take over Fort Knox (while the soldiers were only pretending to be dead) so that Goldfinger and his men would bring the atomic device to the fort, where it could be seized and defused. If they had not allowed it in, the other henchmen could have used it elsewhere.
During the "laser" scene, Goldfinger reveals that Bond has been outed by "one of your opposite numbers, who is also licensed to kill". MI6 has not been compromised; an "opposite number" is a person's counterpart within an opposing force, so Goldfinger is referring to a spy from another country.
When the atomic device is activated, the timer can be seen and heard ticking at a rate that would have detonated the device long before it was actually disabled. But the ticks do not represent seconds, and the film is not shot in real-time.
During the "laser" scene, Goldfinger reveals that Bond has been outed by "one of your opposite numbers [an enemy agent], who is also licensed to kill". Only MI6 00 agents are licensed (sanctioned) by the British government to kill, but it has already been established in From Russia with Love (1963) that there are SPECTRE and Soviet agents licensed to kill. Later films in the series confirm this, so Goldfinger is telling the truth.
The reflection that Bond sees in the girl's eye isn't a mirror image like a true reflection would be.
When the crusher picks up the 1964 Lincoln Continental, as it lifts the car, the weight of the engine causes the car to tilt forward, however, with so much gold in the trunk, you would expect the car to stay level or tilt backward.
The common misconception of junkyard operations is that a car is taken "raw", squeezed, and simply compacted into a two-foot cube as depicted. In reality, the glass, rubber, metal, plastic, vinyl and other materials are all run through a chopper, which breaks down everything into small parts which are then separated according to the material type. The metal (steel and iron engine parts, chrome bumpers, etc.) is magnetically separated from the scrap, and Goldfinger's gold, being non-magnetic, would not have stuck to the magnet and would been mingled along with all the other virtually worthless scraps.
A standard gold bar used by banks and bullion dealers weighs 400 troy-ounces, or 27.5 pounds each. Goldfinger's henchmen are transferring the gold bars to the truck as if they weighed almost nothing.
When the "Flying Circus" planes land and taxi to a stop, one can clearly see that the pilot of the nearest plane, who is looking at the camera making sure not to hit it with the wing, is a burly man wearing a blonde wig. It is basically a yellow hat with pigtails.
The maximum payload of a 1964 Ford Ranchero was only 800 pounds. The weight of the crushed 1964 Lincoln Continental plus Mr. Solo's gold was about 7,154 pounds not including Solo's body. No way the Ranchero could haul that much.
The real interior of Fort Knox doesn't look anything like in the film, it's also much more secure. However, the filmmakers had --no way of knowing what the interior really looked like at the time.
The helicopter that delivers Pussy Galore, Goldfinger and the "nuclear device" to the depository has the registration N-ASAZ. Aircraft registrations in the USA haven't used the "N-and four letters" system (as used in the UK, for instance, with G in place of N) since 1927.
There are no children or elderly people in the hotel pool area only young and athletic looking men and women.
When Auric Goldfinger is talking to Mr. Ling about the process of melting down the gold from the car, his lips never move.
After Goldfinger's been beaten at Gin Rummy and snaps a pencil in anger, we hear this while we're seeing through Jill's binoculars. We wouldn't be able to hear something like that from Jill's vantage point, several floors up from the pool area.
In the first dialogue of the pre-credits sequence, when Bond chats to Sierra just after the explosion, the actor playing Sierra has clearly been dubbed.
After Goldfinger writes a check in his car, he closes the door. You can clearly see the film crew in the reflection of said door.
As Bond regains consciousness after being struck by Oddjob, the shadow of the camera and boom moving is visible on the bottom of the cupboards.
When Bond drives his Aston Martin between the buildings of Goldfinger's facility, the studio roof is visible instead of a clear night sky.
The stage lighting is visible in the vault door, even as it opens.
When Felix and his partner are following Oddjob to the airport, thinking they are tracking Bond, palm trees are visible in "Kentucky".
When Bond is tracking Goldfinger's car in Switzerland, the map on his dashboard show's Goldfinger's blip moving north from Geneva along a lakeside road, yet the shots of the cars indicate a high mountain pass.
When M accepts a call from Washington, the audience sees that Felix Leiter has the White House just outside his window. The White House is a considerable distance from the CIA in Virginia and no building has a clear unobstructed view of it.
When Leiter contacts M on the green scrambler, the south portico of the White House is shown through a window behind him. There are no structures directly south of the White House to the Tidal Basin except for the Washington Monument.
When Bond is driving to the Auric Enterprises building (in Switzerland), he's seen driving on the left hand side of the road but he should be driving on the right hand side in Switzerland (as shown in the previous scene).
If Bond's car has a bullet-proof rear window, as Q explains, there would be no need for a bullet-proof rear sliding panel.
After ejecting the guard, Bond tries to make his escape back out the front gate. However, he is thwarted by the old lady with the sub machine gun and ends up driving away and in the ensuing chase, crashes and is captured. Bond should have just keep driving out the gate since he knew his car and windows were bullet proof and he could have deployed his headlight machine guns to easily eliminate the lady.
Mr. Solo is driven away by Oddjob, who then shoots him before the car is crushed. Oddjob then has the remains loaded onto an open truck, which he drives back to the stud farm. Goldfinger then tells Bond that he has to arrange to separate Mr. Solo from his gold. Seeing as Solo had been shot, the simplest thing would have been to put him into another car for disposal, and return the original car. That way Solo's body would have been hidden and the gold could have been simply taken back out of the car without the need for a complicated separating process.
When Goldfinger is getting ready to slice Bond in half with his laser Bond claims he knows all about Operation Grand Slam. All Goldfinger would have had to do was tell Bond to tell him what Operation Grand Slam was and Bond would have been dead meat because he obviously couldn't have done that.
When Bond is fleeing with Tilly, he turns left at a fork in the road. Having driven the road and scouted the area during daylight, Bond knew that a cliff was in that direction. In short, he intentionally drove towards a dead end.
Bond squeezes the plastic explosive out of its packaging before laying it. This is unnecessary as it would have worked while still wrapped and as a professional spy he should have known this. Also it just increases the time that he might get caught and stopped.
The U.S. Army Brigadier General is addressed as "Brigadier"; U.S. Army, Air Force and Marine Corps officers of this rank are addressed as "General", since in the U.S. military it is a General officer's rank. "Brigadier" is strictly a British or Commonwealth form of address. It's understandable that Bond might make this mistake, but Leiter, an American, should know better.
When Bond disables Tilly's car, not only does he bust her tires, he also tears the side of her car to shreds. Yet Tilly makes no mention of this when she examines the damage, only remarking about her blown tires.
As they watch him meet up with "his pigeon", Felix tells Bond: "That Goldfinger's a fabulous card player." It takes Bond less than a minute to deduce Goldfinger is "a fabulous card player" because he cheats, yet Felix, who has had Goldfinger under surveillance for a week, didn't figure that out.
After the bomb is diffused, Bond says: "Three more clicks and Mr. Goldfinger would've hit the jackpot.", indicating there were 3 seconds to detonation, but the clock shows "007". It originally showed "003" but was altered as an afterthought by which time Sean Connery was unavailable to redo the line.
