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.
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.
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.
Speaking to Jill Masterson, Bond claims that the champagne should be drunk at 38 Fahrenheit, this is 3.3 Centigrade and barely above freezing. Most wine experts recommend 7 to 9 Celsius which is 43 to 48 Fahrenheit.
When Pussy Galore's Flying Circus takes off for its lethal run towards Fort Knox, one of the pilots says, "Speed: two-two-oh. Wind check: westerly." Flying speeds are usually given in knots, and the top speed of a Piper Cherokee 180 (the type of plane used by the Circus) is approximately 130 knots, not 220. It's unlikely that the pilots would use KPH (130 knots is roughly 240KPH).
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.
Bond tells Pussy Galore that if she fires the gun at him at close range that the bullet would pass through him and the fuselage and that they'd be sucked into outer space. As a rule of thumb outer space does not begin until a minimum altitude of 100km at the Kármán line, while most planes rarely exceed an altitude of 10 km.
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.
When Pussy Galore's Flying Circus lands at Blue Grass Field, the blonde girl we see getting out of the first Piper is not among the group of pilots who report to Pussy in the next shot. When the girls are dismissed, there are no planes in the background.
When Felix Leiter and the other agent follow Oddjob and the soon to killed Mobster to the airport, the Ford Thunderbird they are driving has no "fender skirts", or coverings for the rear wheel openings on some luxury cars. After they loose the signal in Bond's transponder, they return to Goldfinger's ranch, and as they pull up by the fence, the T-bird suddenly has fender skirts.
At the Miami resort, when Goldfinger walks towards the card table, on the far left you can see Bond and Leiter standing watching Goldfinger in the background. In a close up shot of Bond and Leiter we see Bond reaching for a towel and putting it on his shoulder, but then in the wide shots there is no towel over his shoulder and he never moves.
Before Goldfinger joins his opponent at the card table in Miami, the cards are blue, but when Goldfinger sits down and they begin the game, the cards are red. (There is another deck of cards on the table, also red, but they remain untouched throughout the scene.)
When Bond is listening beneath the model of Fort Knox, just after he is caught by Pussy Galore, his vest has one button undone. But is the next shot, still standing in the same place, the button is done up.
In the intro scene, while Bond deposits the explosive along the drums labeled 'Nitro' you can see that his hands are all grimy. After he climbs back over the wall shortly after and takes off the overalls his hands are clean.
In the car chase between Bond and Tilly Masterson, Bond opens the control console hidden beneath the arm rest, you can see that the entire sleeve is black but in the earlier and the following scene Bond's wearing a brown jacket and a white shirt.
Goldfinger's Lockheed Jetstar has "Auric Enterprises" written on the nose in the airport shots, but it's not on the model in the flight shots. (Lockheed had the company names put on the Jetstars during production to remind the workers of the importance of their clients.)
At the Florida hotel Bond is giving Goldfinger orders over the radio system. We see two close-ups of Goldfiger holding the cards and a gold ring is clearly visible on his little finger, left hand. The next two shots of Goldfinger are face on and the ring has moved to the fourth finger, left hand.
When Bond enters Goldfinger's hotel room in Miami we see that the transmitter is on the table next to Jill. Bond turns it off but when Jill turns around and says, "Who are you?" we see that Bond is too far away from the table to have just turned off the transmitter.
After the golf duel Goldfinger takes a seat in his car to write a check. After this, Oddjob is crushing a golf ball with his bare hands and then drives away. When the passenger seat is shown, Goldfinger is not in the car.
In the cantina in the pre-credits sequence, Bonita can be seen reflected in the mirror, and a man is lighting a cigarette for her. In the next shot, she storms out of the cantina with no cigarette, and the man has suddenly disappeared.
Goldfinger's minions are shown parked in several U.S.-Army-disguised trucks ready to invade Fort Knox. One of these is clearly a 1958 or 1959 Chevrolet Viking. As the trucks move out, the 1958-1959 Chevrolet Viking truck completely disappears, although the same number of trucks are still shown.
When James has just been passed by the Mustang on the mountain road, then he stops and looks at Goldfinger and Oddjob buying fruit from the children far below on the lower part of the winding mountain road, Goldfinger takes a bite of his fruit as he is walking our right to left. When Goldfinger is shown in the next shot, viewed from up above, where James is, he is still standing and looking/talking to the kids, not having walked away, or, it would seem, having taken a bite of his fruit.
In the JetStar, when Bond wakes up. Lighter on the table changes place from Bond's side of the table next to ashtray, when the rear of the plane is visible, to Pussy Galore's side of the table when the front of the plane is visible.
When Oddjob leaves the Continental at the salvage yard there is no front windshield when the claw comes down to pick it up. When the claw drops the car in the crusher bin the windshield has reappeared.
When James has just been passed by the Mustang on the mountain road, and then he stops and looks at Goldfinger and Oddjob buying fruit from the children. As Bond stops and exits the car he is quite a distance from Goldfinger and there are 5 unbroken stone bollards visible. In the next shot Bond and the Aston Martin have suddenly moved much further down the mountain and the Bollards are different, some are closer together and the one nearest Bond is broken.
After the game of golf, Goldfinger sits in the back seat of his car and makes out a cheque to Bond. Once he receives the cheque, Bond gives the golf ball to Oddjob (who is in the driver's seat). Oddjob crushes the ball and drives away, but Goldfinger is no longer in the car.
At the airport when Goldfinger's Rolls is being loaded onto the cargo plane, Bond reaches into his car and turns on the radar unit. The bleeps shows the Rolls and the plane are taking off from the south end of the runway when they haven't even started the engines yet.
During the golf game, Bond is standing to the left and slightly behind Goldfinger. Yet the bar of gold 007 drops lands to Goldfinger's right. When we see Bond in the next shot, he's still in his original position.
When Bond is speaking with his fellow agent at the bar after blowing up the heroin plant, a large mirror behind the bar shows Bonita talking with several other men in the middle of the room, yet in the very next shot she's alone, much farther away from where she was, and storming her way up the stairs.
When Bond takes over the communications, the focus of the binoculars changes from the other players gin rummy hand to Goldfinger's face, and then later to his hand when he snaps the pencil. Neither Bond nor Jill every touch the binoculars which are mounted on a stand.
The Falcon Ranchero that Oddjob uses to remove the remains of the Lincoln initially has blackwall tires and in the final scene where it passes the agent's T-Bird it has whitewalls. When it arrives back at Goldfinger's compound it has blackwalls again.
When Bond drops Tilly at the service station, the mountain peak back up the road is partially obscured by clouds and overcast. A few seconds later, when Bond drives away, the mountain peak is cloudless and sun-bathed.
In the first shot of the "Pigeon" he can be seen shuffling a deck of blue back cards. In every clip that follows where the cards are visible they are red back, including the 2 decks sitting on the table.
When Bond and Jill are in a hotel room bed, she is first shown laying on top of the bedclothes, but after the phone rings a shot from another angle shows her with blankets tucked tightly around her waist.
In the opening scene, when Bond approaches those huge metal cylindrical containers, the walls are almost completely smooth, constructed of large panels of metal (a few feet taller than Bond). When he gets closer, the panels are much smaller (he has to crouch to get inside) and the joins are much more obvious.
Near the beginning of the film when we are flying across Miami to the hotel, the guy dives into the pool, but in the corresponding shot from inside the hotel when we see the pool underwater, he appears to have dived in from the side, not straight on. Additionally, you can clearly see that there's no huge glass window for spectators within the hotel, and there's nobody else in the pool, so the girl who swims past seems to have come from nowhere.
On the first green shown, Oddjob has Goldfinger's golf bag on his shoulder. As Goldfinger finishes his put, Oddjob can be seen in the background with the golf bag off his shoulder on the ground. As the camera moves, Oddjob has the golf bag on his shoulder.
During the car chase at Goldfinger's Swiss warehouse the car that slides down the hill on fire and crashing is has hardly any body work damage when it hits the wall of the building at the bottom of the hill.
In addition to the jeep changing from the WWII type to the 1950's style in the procession to Fort Knox, the large trucks change from Chevrolet trucks when they are going through the town to International trucks where the main actors appear. This can be explained due to the fact that background scenes were photographed in Kentucky and principal photography was done at Pinewood Studios in England.
The high-angle zoom-out shot of the Aston Martin parked in the Alps clearly shows a horizontal dent along its left front fender and driver-side door. Shortly after, when Bond offers Tilly a ride, the dent is gone.
Tilly's gun case is shown to be placed along the back window of the Aston Martin when Bond drives her to the garage (which is how he's able to note her initials on the case), yet when they park and Bond retrieves it, he takes it off the rear seat.
After one of Goldfinger's guards has been ejected through the sunroof of Bond's Aston Martin, a chase ensues through the smelting plant. The sun roof panel is clearly missing throughout the chase. After eluding his pursuers, Bond is confronted with a with a car apparently "playing chicken" by apparently approaching him at full speed. Firing his machine guns, Bond he is forced to swerve into the wall of an adjacent building to avoid collision with the enemy car. An examination of the resulting accident scene shows the sun roof panel has mysteriously returned to the car.
During the Swiss drive just before Bond slashes Tilly's tires, the cars enter a straight section of road with train tracks to Bond's right. At different points in this sequence the cars are shown back at the start of the straight section again. During close-ups of the tire shredder and Bond's car, there are no train tracks visible anymore. Also, during close ups of Tilly in her car, the road is curved and not flat. Finally, after the tires are slashed, Tilly is suddenly in front of Bond as she loses control of her car.
When Goldfinger confronts Bond in the plane near the end of film, a crew member is briefly seen when Goldfinger initially steps from behind the curtain. You can then see the curtain is open behind Goldfinger, but moments later it is closed. About 30 seconds later, when Goldfinger says he will take care of Pussy, you can see that same film crew member again, his left arm is sticking out from behind the curtain. After the explosive decompression, the crew member can be seen lying on the floor, either unconscious or dead. We could assume that he ended up that way because of the explosive decompression, though it doesn't explain why he doesn't help Goldfinger when he fights Bond.
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 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 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).
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.
A 1964 Lincoln Continental, including the weight of the gold in the trunk, would have weighed more then 5,000 lbs. which would have snapped the rear axle of the 1962 Ranchero wagon it was loaded on, not to mention, the rear would have dropped considerably before the axle broke.
The interior scenes in Pussy Galore's JetStar are filmed in a sound stage far too large to be the interior this particular aircraft. The JetStar interior barely fits two small seats side-by-side with a tiny isle in between. Additionally, Bond would not be able to stand up-right in the cabin of a JetStar.
Among the equipment Q gives bond is a magnetic transmitting device, a homer. Bond attaches the homer to the roof inside Goldfinger's car's trunk after their golf game. Later, as the car is being dismantled, Goldfinger says, "The bodywork of my Rolls Royce is 18 karat gold." Only metals contain iron are magnetic. The magnetic tracker would not adhere to Goldfinger's gold Rolls Royce.
During his briefing, Goldfinger correctly states that 41,000 troops are stationed at Fort Knox. The commander of Fort Knox in the film is a brigadier general, but an officer of higher rank would be assigned to command such a large body of troops, and in fact, no modern commander of Fort Knox has ranked lower than major general.
Pussy Galore's aircraft depart to Fort Knox. Lead aircraft reports "Speed 2-2-0,wind check, westerly". Piper Cherokees have never been capable of any speed 220 mph, 220 kts or 220 kph. in level flight. 130 mph is typical cruise speed. However, it is possible that the pilot was stating the speed in kilometers per hour, 220 kmph would be approximately 136 mph
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.
After the Lincoln is crushed, it is gently lowered onto the bed of Oddjob's Ford Ranchero pickup, which would have crushed it. A '64 Lincoln weighs close to 5000 lbs, not counting the the extra weight of the gold that was supposed to be in it (or the body... ), and that year Ranchero had a max load weight of approximately 1000 lbs. A mid-sixties Ranchero was built on the Falcon chassis.
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.
In shots of the interior of the Aston Martin (looking toward James, on the day of the mountain road "chase") the screw holes where the sun visor used to be attached inside the Aston are plainly visible.
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.
In the auto chase seen at night with Bond and Tilly, Bond puts down an oil slick and the car chasing them slides off the road towards a cliff. The car burst out in flames for no reason at the top of the cliff.
When Bond uses the device to slash Tilly Masterson's tires as she passes, the camera shows the tires wobbling even before the blade touches them. After being sliced by the blades, the tires are clearly shown coming off of the rims. Yet when the car goes off the road, the tires are still mounted and inflated.
The goof items below may give away important plot points.
When the Flying Circus planes "knock out" the 1st Armored Division troops with gas, soldiers depicted in various scenes with weapons are correctly equipped with and holding the then standard-issue M14 rifle. However, when Leiter and the General counter-attack the depository, their assault troops are carrying superseded Thompson Sub-Machine Guns and M2 Carbines. Though technically not fully removed from service at the time, these World War II vintage guns would not likely be employed with soldiers from a unit already equipped with the newer M14. (The Chinese/Korean extras in this scene are also using obsolete bolt action rifles and WW II German MP 40 SMGs.)
The bomb is disarmed with 007 seconds left on the placed timer with big white numbers. Then, Bond says "Three more ticks and Mr. Goldfinger would've hit the jackpot." Originally, the timer would've stopped at 003, and the line would make sense, but later it was decided to stop it at 007 instead for a good old Bond joke, and apparently someone forgot to delete that line in editing.
When Oddjob first throws his hat at Bond inside Fort Knox it lands at an angle where the floor is made of tubing. When he runs after Bond and picks up the hat it is now the right way up on solid flooring to the left.
Right after Goldfinger appears in the plane at the end of the film, a quick cut reveals several military personnel (the pilots?) bound and gagged on the floor inside a hanger - they are all awake and struggling to get free. Moments later, the scene cuts back to them as they are discovered by several men- only now, they are lying perfectly still - apparently unconscious - on the floor.
When Goldfinger's vehicles are on the road approaching the Fort Knox Depository, you can clearly see an army truck laying on its side with men around it. Later when the men are "waking up" the truck is upright.
When Oddjob cuts the statue's head off at the country club, a close-up of the underside of the hat reveals a sturdy-looking metal ring lining the brim of the hat, making it into a formidable weapon. Later on in Fort Knox, however, when James Bond retrieves the hat from between the bars and throws it at Oddjob, several shots of the underside of the hat reveal no silver ring.
When Oddjob wrestles the pipe from Bond's hands at Fort Knox he steps in to execute a right handed ippon seonagi (Judo technique for one-armed shoulder throw) and as the camera moves to an over-head shot he has switched arms and throws Bond into a wall.
When Bond and Oddjob fight in Fort Knox, after being thrown in the direction of the electric cables (one of which Oddjob's hat has already sliced) Bond picks up Oddjob's hat and he makes to throw it with his left hand the shot changes to show Oddjob trying to anticipate where Bond will throw the hat and when it cuts back to Bond he throws it with his right hand.
When Bond first sees golden Jill on the bed she is lying diagonally across the bed with her right foot on the bed and pointed like a ballerina on points. As Bond approaches the bed her right foot is pointing towards the camera. The last shot of Jill's legs show both her feet hanging over the end of the bed meaning that she has changed position and is now lying straight along the bed.
We see Bond and Pussy in the cockpit fighting to pull their jet out of a dive. At such an angle and speed it would not be possible to get out of your seat, find parachutes, put them on, open an aircraft door and jump for safety.
When Auric Goldfinger pulls aside the curtain to approach James Bond aboard the aircraft bound for Washington, DC, a Chinese henchman is visible to Goldfinger's left. This character all but disappears and does not come to the aid of Goldfinger when his struggle with Bond commences.
During the fight with Oddjob in Fort Knox, Bond picks up a stick-like object off the floor as a weapon. The next shot, showing Bond wave the stick and begin to launch it at Oddjob, uses a stunt double whose hair and physical build are different from that of Sean Connery.
As Bond is flown to the White House near the end of the film, the American flags on the right-hand side of the plane are backwards. Although images of the flag are normally displayed with the field to the left, protocol demands that on vehicles the blue field of the flag is towards the front of the vehicle (as if it is blowing in the wind as the vehicle moves forward). The flags in the movie have their field on the left, which is backwards for the right-hand side of a vehicle.
Oddjob leaves the Contintental (and Mr. Solo) at the scrapyard to be crushed. A grappling hand comes down and seizes the roof & lifts the car above the camera. You can see daylight in the engine compartment at a diagonal angle. This shows the engine has been removed before the car's dropped in the compactor and crushed.
