When Bond has infiltrated and is escaping from Osato Chemicals for the first time, the security guards that are shooting at him are using silenced revolvers (at least the ones inside the building), yet when they fire, the noise made is that of an unsilenced weapon.
When Tanaka demonstrates the rocket-propelled bullets for Bond, just before he fires the bullet, his mouth starts moving as if he is saying something, but no words come out. Also, in the next line, Tanaka says something incomprehensible, which sounds like "All rocket gun" or something similar.
After Little Nellie has been assembled, Tanaka calls it a "toy helicopter". Little Nellie is actually a type of aircraft known as an autogyro, and Tanaka should have been able to recognize the difference between the two types of aircraft. However, since the average viewer would not know the difference it is possible that the producers intentionally allowed the incorrect reference to stand.
When Bond first arrives at the ninja training camp, some of of the ninjas are sword fighting. It is assumed that they are sparring (with no real contact) because the ninja in blue obviously misses several of the others very badly with the sword, but they faint as if hit. However, two of the ninjas scream loudly in pain when they are "slashed" which makes it unclear whether they are sparring or using real contact.
Henderson states that he has lived in Japan for 28 years. Assuming that the film takes place in the same year that it was released, that would mean that he was living there since before the Battle of Singapore in which he admitted to having taken part in. It is extremely unlikely that he would live in Japan after Great Britain had declared war, fought in the Battle of Singapore, and then still lived in Japan.
The ninjas outside the crater are armed with Spanish Star Z-45 submachine guns and Thompsons. When they are inside the volcano, they mostly use British Sterling and Sten submachine guns. This is because the exterior shots were filmed in Spain, while the volcano set was in Pinewood, UK.
On a monitor in Aki's car Bond sees Tiger's helicopter from above lifting Osato's gunmen's car. But there is only one helicopter shown in all the other shots so this leaves no place for Tiger to have placed a video camera that would be able to transmit the picture Bond sees.
When Aki is driving Bond to see Henderson, she is driving a car with the steering on the right side. As they approach Henderson's residence, Aki is seen briefly to be on the left side of the car. When the camera cuts to a close-up, she is back on the right again.
After Little Nellie has been assembled, Bond gets aboard. A technician is seen to begin the removal of the red rotor brace. The next close-up of Bond sees the brace in position. The next longer shot sees the technician completing the removal of the rotor brace.
When Osato and Brandt land on the helicopter landing pad to meet Bond (as Mr. Fischer), the helicopter lands across the top of the "H" on the pad, near the edge of the circle, and it is facing slightly to the left of the camera. After a close-up of the tail rotor, the helicopter is now resting along the side of the "H", is further inside the circle, and is now facing to the right.
When Bond kills the ninja who surprise attacks him, he clearly stabs him in the hip. In the next scene, the blood is on the ninja's torso, and not his hip. Also, there is no blood on the weapon, either.
When Helga Brandt traps Bond in the plane and bails out, the plane was shown retracting the landing gear after take-off and after she bailed out the plane in the background had the gear down, (or it was a different version of the plane with non-retracting gear)
While flying Little Nellie during the engagement with the SPECTRE helicopters, Bond expends all of his weaponry. Afterward, however, when Bond is told to proceed to a certain position, the helicopter is seen pulling away fully armed.
When Bond is being suited up by the astronaut and cosmonaut, they connect the blue inlet hose of the air conditioner to the left connector of his suit and the red outlet hose to the right connector. However, when Bond arrives at the Spectre rocket, the hoses have switched sides.
When Bond and Kissy are in the rowboat, her position changes very rapidly between angles, The time of day changes even more so. First, the sun is setting, and is high in the horizon. Next, the sun is setting and is very low in the horizon, almost night time. Next, it is about mid day, which would mean that either there is a continuity error with the footage, or Bond and Kissy and the others stayed out rowing all night long and into the next day, which also makes no sense. The sun is not setting, it is rising. Ama fisherwomen start at dawn.
Before Bond (disguised as a SPECTRE astronaut) is brought before Blofeld in the command room, the 'Blofeld' sitting in his chair has hair which can be seen briefly from the rear of the chair. However, when he introduces himself to Bond a moment later he is clearly bald.
Just before Bond opens the safe at Osato Chemicals he drinks some "Siamese Vodka". Then there is a shot of the safe that includes the outline of his overcoat. When the camera returns to the same safe shot there is no overcoat outline and Bond walks toward the safe from off-camera.
Bond stows away on a monorail cart which stops at the astronauts' quarters. After Bond gets out of the cart, a second cart passes by, even though the cart he arrived in is still on the track (out of shot). No one moved the cart before the second cart passed through.
When Bond is being chased across the roof of the warehouse in the harbor, a helicopter shot of this taking place shows that a roof door is open as Bond approaches. The next shot is Bond by that same door and it it closed.
After Bond gets the tickets from Sadonoyama and walks into the arena, the "referee" for the match is wearing a red robe. In the scene when Aki comes in, the "referee" is wearing blue. It's possible the "referee" was rotated out with another one, especially if there is some delay between Bond sitting down, and Aki arriving.
When Bond is setting off the self-destruct for the "pirate" spacecraft, the timer is not synchronized between the two different camera angles. In the first camera angle, it starts off, counting, 28, 27, 26, 25, 24. It then cuts to a different camera angle, and it counts, 14, 13, 12. It then goes back to the original camera angle, and it counts, 24, 23. It then goes back to the other camera angle, and finally counts down, 12, 11, 10, 9...
When Bond is flying Little Nellie and looks behind him to see the shadows of the helicopters chasing him, there are five shadows. When the helicopters are shown, there are four. (Bond's Little Nellie shadow was clearly shown to be ahead of the other helicopter shadows).
In the Russian launch sequence the rocket shown lifting off from the pad is an American made Titan III-C ICBM modified to launch the Gemini series spacecraft. Also there are palm trees in the foreground which indicates a tropical location far south of the Soviet Baikonur Cosmodrome complex.
It's 1796 miles between Hong Kong (where James Bond is "buried at sea") to Tokyo, (where 007 goes to next). That means that James Bond would either spend several days on the submarine traveling between the two cities or try to get from Hong Kong (where he was publicly "murdered") to Tokyo, (by air) without being noticed.
Representatives from the UK, US and USSR meet each other in Norway. Normally, representatives use vehicles produced in their own country, but the three cars in front of the facility are two Plymouth and one Cadillac - all American-made.
Objects in "identical" orbits cannot overtake - they must travel at exactly the same speed to be in the same orbit. For the SPECTRE capsule to overtake a target, it would have to approach from below and perform a complex maneuver to engulf the target. Any maneuver by the target would cause a miss.
When the Russians launch their ship, they are talking about stats of the Sputnik. In Russian, the technician says that it is 36 degrees while the English subtitle reads 72, which is not possible. 36°C is 96.8°F. A further error is that the capsule atop the rocket is not only not the one we later see being captured; it is a US Gemini spacecraft. The Gemini vehicle was first launched in 1964 and was in use until the end of 1966. There were two unmanned and ten manned flights. In 1967, the Soviet Union was already using the Soyuz-class spacecraft.
During the opening movie sequence (tracking station) "Hawaii" can be heard calling "Jupiter 16" - this is contrary to proper protocol. Tracking stations only relay communications between Houston and the capsule. To reduce confusion during missions NASA capsule communications ("CapCom") was through one individual (always an astronaut) at NASA-Houston ("Houston, we've had a problem here"). One exception to this was during the launch phase when Cape Canaveral ("Launch") was the only communications point. This protocol is still in use today.
Blofeld tries to shoot Bond, and the gun gets knocked out of his hand with a ninja star, and goes off. The gun hits the ground, and goes off again. This is impossible for two reasons. The gun was never re-cocked, and the angle that the gun hit the floor would not have set the trigger off.
Possible deliberate Cold War omission by filmmakers, when the SPECTRE spaceship attacks the American spaceships it has Russian markings of CCCP and Red Star, when the SPECTRE spaceship attacks the Russian spaceship it is clean skinned. To show a continuity of plot, it should have American markings, no doubt this is deliberate by filmmakers.
Towards the end when the US move to a "higher security" status we see a TV shot of a B52 taking off (presumably to drop nukes on the Russians). The active B52 fleet was kept in the air permanently flying "holding patterns" towards Soviet territories being relieved every few days.
While at the Kobe dock, Bond notices condensation on some chemical tanks, and says that he thinks they might contain liquid oxygen, because they're cold enough to cause the condensation. Real LOX tanks would be extremely cold (at least -140 °C to be below oxygen's critical temperature, and down to -183 °C for the boiling point at atmospheric pressure). So the tanks would have to have very good insulation to merely feel cold to the touch rather than, say, cause blisters or instantly freeze Bond's hand to the tank. Also, the LOX would be boiling, and the gaseous oxygen this produces needs to be constantly vented, causing a visible plume. A fully closed tank as shown in the movie would soon explode due to the build-up of pressure.
From the layout of the compartment through which Bond enters the submarine it is an conventionally-powered SSK type (although the external shot shows a nuclear-powered one) that means the M's office splits the submarine in two making it impossible to get from one end to the other.
When Q introduces the Little Nellie gyrocopter he describes the twin machine guns as "synchronised". An interrupter gear (also known as synchroniser) is used when machine guns are placed to shoot through the propeller disc, in order to prevent damage to the revolving blades. However, Little Nellie has "pusher" configuration, with the propeller placed behind the pilot's cabin, thus negating the need for the machine guns to be synchronised at all.
In the pre-title sequence, Hawaii tracking reports an unidentified craft closing fast on the American spacecraft from astern. However, when the spacewalking astronaut makes visual contact with it, he is facing forward.
The fastest variant of the Bell 47, the helicopters chasing "Little Nellie," could only go 105 mph flat-out, while the Wallis WA-116 could go over 25 mph faster. "Little Nellie" could have easily outdistanced her pursuers had Bond chosen to do so. While one could say that "Little Nellie" was weighed down with ordnance, so, too, were the Bells.
Bond undergoes extensive makeup, a giant wedding ceremony, and works as a fisherman for a day in order to pass as a native in front of hundreds of people who attended the wedding so he could get to an apparently uninhabited island. A wet suit and rebreather would have accomplished the same ends.
Whether Bond is known to be alive to SPECTRE agents in the film is inconsistent. Blofeld believes Bond to be alive as he was carrying a Walther PPK in Osato's office. Yet Osato and Brandt did not even believe Bond to be alive to begin with, believing his cover story to being dead to be real. If Osato did not know "Mr. Fisher" was actually Bond (and believed Bond to be dead) why did he give the order to kill him? Furthermore, how does Osato know Brandt failed to kill him? They have no way of knowing this.
How does Blofeld have a side view of the satellites in outer space? This would mean that he would need to have an additional spacecraft with a camera attached. In that event, the astronauts would notice two spacecraft approaching instead of one.
While Bond and Kissy are climbing the volcano, his "Japanese" make-up disappears somewhere along the way. It's unlikely he could have casually pulled it off and tossed it away; he also had no way of knowing he wouldn't be needing it again.
SPECTRE's aim in the movie is to create a war between USSR and USA to put China in a dominant position. Given that both USSR and USA were nuclear powers, what exactly did SPECTRE expect would be the outcome - either they would back down as in the Cuban missile crisis so the plot would fail or they would 'an-eye-hill-eight' each other leaving the world facing nuclear winter. Whoever is head of strategic planning for SPECTRE needs a visit to Mr Blofeld's piranha pool.
When James Bond is in Tanaka's underground train enjoying the sake wine. One servant enters saying that the photograph is ready for viewing. This servant then walks to the door, which is on the left-hand side of the carriage. After going through the door, we can see the servant taking a left turn, but where to? Outside the moving train?
Construction of the Volcano HQ would have taken considerable time and resource, it is inconceivable that no-one in the local area would have noticed or commented, let alone undertaking such a monumental project without Japanese intelligence being aware.
Blofeld 'recognises' Bond via his use of the Walther PPK 'the only person we know who uses the gun'. Given, a) Bond was given this to replace his Beretta in Dr No and therefore an MI6 choice not Bond's and b) SPECTRE is a criminal organisation that must deal with a large number of armed people they must know other users, Otherwise it would mean that Walther only supply James Bond with the PPK model.
When Bond leaves Osato's office after meeting with him, Osato turns to Miss Brandt and orders, "Kill him." When Osato says this, Bond is not even out of his inner office, the doorway is wide open, and Bond should almost certainly have heard him.
While rolling the SPECTRE rocket on to the platform only one of the visible wheels under the platform spins correctly. One of the four wheels doesn't spin at all. The left wheel spins in the wrong direction.
As well as his grey commando fatigues (and balaclava) under his white Japanese fisherman's costume (beneath which he clearly wasn't wearing anything, as previously noted), Bond also produces sucker pads for his hands and knees, an equipment belt, a cigarette case.
On a monitor in Aki's Toyota, Bond sees the helicopter flying with the car it has picked up, from about the same altitude. But where would the camera be? Bond seems to be watching the same movie we are.
When the Hong Kong police pull up in front of the building where Bond has been "shot", a crowd of people is assembled on the corner behind them, obviously standing there watching the filming. A small group of people is also inside the shop adjacent to the same building, also clearly watching the filming.
When Aki and Bond leave the Sumo match, she drives him in her 2000GT convertible. Like all cars in Japan, the driver (Aki) is on the right side of the car. However, when they pull up to the hotel, their positions have switched. She (and her powder blue head scarf) are now on the left. The film strip appears to be reversed, as they park with the right side of the car facing the hotel door, but in the next shot, the left side of the car is facing the door.
When Bond's "body" is dropped off the ship and later picked up by the scuba divers it is absolutely rigid yet, when inside the sub, it bends and moves like a real body showing that the original "body" was actually a dummy.
After Bond kills the ninja that surprise attacks him, Tanaka comes over to check on him. The man's body is lying flat, with the back of his head resting on the ground. When Tanaka comes over, he crouches over him, pushes his head to the side and checks his pulse. In the next camera shot. The body is back to the original position (with the head flat), and Tanaka has disappeared. This is clearly the same video clip re-used from moments earlier, when Bond first killed him. Again after this, Tanaka is crouched over him again, with the head turned to the side.
At the end of the pre-credits sequence, just after Bond is "assassinated", there are bullet holes visible through the bottom of the bed. The bed is dropped back down and Bond is "dead". In the padded section behind where Bond would have been when the bed was upright, there are several bullet holes visible. Presuming Bond was shot with blanks, these would not have left any bullet holes nor would there be any bullet holes in the bottom of the bed.
When Bond is struggling to pull the Meyers 200A plane out of the dive we see two shots of an air speed indicator. In the first instance this should be going up as the plane power dives (engine is running) and Bond hasn't quite got control yet.
In the helicopter battle, Bond drops at least a dozen aerial mines. However, there is only one big explosion when they hit the helicopter below, revealing that the mines are duds and the real source of the explosion is the helicopter itself.
During the final assault a Blofeld henchman fires two shots at Bond with a bolt-action rifle. The time between the shots reveals the henchman could not possibly have fired those two rounds so close to each other.
The telephones at the Hawaii tracking station are not of the then-standard American design (Western Electric 500 series), but instead appear to be contemporary British GPO (General Post Office) phones.
When Bond reconnoiters the crater from above, he tosses a rock onto the retractable cover and there is a metallic clang and he says, "It's metal". Later, one of Tanaka's ninjas places an explosive charge on the cover from underneath, and the material flexes, showing it to actually be fabric.
In the first scene of the introduction the image of the American space capsule unrealistically shifts in position relative to the star field behind it as the camera moves closer disclosing it to be a double print composite.
When the man with binoculars is observing Bond's funeral at sea, the newspaper on the table shows an article on Bond's murder. This article can be seen to be a separate piece of paper that has been stuck onto the newspaper, and part of the bottom edge has not been stuck down fully.
When the divers recover Bond's body and take it to the submarine, multiple shots show that they are only three or four feet underwater. The submarine in the background is a very small model, as the real thing would have most of the hull and all of the conning tower above water.
During the assault on Blofelds crater-HQ a ninja is seen dispatching several henchmen using his sword. The scene ends with the ninja stabbing the last henchman (dressed in red) with his sword. The sword moves in such a way that reveals the fact that the sword never even touches the henchman.
During the car chase before the helicopter lifts the black saloon off the road, there are a number of interior shots of the while sports car driven by Aki with Bond on board. The dials on the dashboard read 0mph and 0rpm. Either there is something very wrong with the car, or it isn't moving.
When the long shots of the model of the interior of the volcano lair are shown, there are little dolls dressed as various Ninjas, Blofeld soldiers, etc., that bounce up and down unrealistically with every explosion.
The goof items below may give away important plot points.
After Bond blows up Bird One, the radar tracker on the television screen states, "He's blown up. The enemy. I repeat, the enemy has blown up." With only radar data to go by, there would be no way to determine that the capsule had blown up - it would simply have disappeared from the radar track.
Kissy is wearing a striped cover-up over her bikini when she returns to the crater with Tiger, and keeps it on throughout the battle in the crater. After Blofeld triggers the self-destruct and Bond yells "Down the tunnel", she's seen running from the crater and down the tunnel in only the bikini.
As part of Bond's disguise as a Japanese man, they shave all the hair from his chest. Yet in the final scene of the movie, when Bond and Kissy are in the lifeboat, Bond's chest is quite hairy, even though this is only a few days later.
When Blofeld's control room proves to be less than "impregnable", he flees with some of his henchmen and Bond in tow. Blofeld takes a Webley from Mr. Osato and shoots him with it. He then cocks it and motions at Bond with the pistol. The gun is blasted from his hand and goes off, yet when it is shown on the ground in close-up it is cocked again. The hammer would have to have been re-cocked by hand. Bond then grabs the weapon as Blofeld flees. He joins the ninja assault wielding the top-break British revolver but as he fights, it changes back and forth several times into a Smith and Wesson revolver with a swing out cylinder.
As Tiger and his men swim away from the exploding volcano they are seen to be urgently thrashing their arms and legs in their haste to escape. In the next, closer shot they are leisurely swimming along at a much slower pace before going back to the original, urgent shot.
After fighting and killing Henderson's assassin Bond's white shirt double-cuffs are clearly visible but disappear in the next shot when he looks at the parked car. The cuffs disappear and reappear in various subsequent shots up until he meets Tanaka for the first time.
When the pirate spacecraft explodes just before it engulfs the US spacecraft, because of its close proximity to the craft, any accelerating shrapnel from the explosion would have pierced the hull of the US craft, thereby causing damage and possible endangerment to that craft and its occupants. Yet there is not a scratch nor mention or show of concern of the status of the craft by the Hawaiian tracking station or CapCom.
Just as Bond enters the crater, there is a message audible, that says, that the US Spacecraft will be intercepted. Yet the Ninjas arrive in time. It took Bond and Kissy hours just climbing up the Volcano and yet Kissy makes it to the island and makes it back with the ninjas in time.
Bond and Kissy are prevented from entering the cave passageway to SPECTRE's base by poison gas. At the end of the film, however, Bond, Kissy, and the ninjas escape through the cave with no ill effects.
After Blofeld sets off the explosions to destroy his volcano complex and the Ninjas are running down the tunnel and swimming out of the cave. There are a couple views of the cavern during the explosions. Several bodies are laying on floor and steps dressed in Blofeld's uniforms. They are rigid dummies and the explosions cause them to bounce like mannequins.
Extremely obvious stuntman. When Bond is fighting Hans in Blofeld's quarters, he appears to be about the same height. When Bond back-drops him into the water, he appears to be about a foot shorter. (This is 5.5-foot stuntman Bob Simmons).
Late in the movie, Bond uses a rocket-cigarette to kill the operator of the crater roof and he moves in to open the roof. A few seconds after he fires the cigarette-rocket, one of Blofelds henchman calls out over the inter-com: "Armed guards to the control-room." That voice was made by actor Burt Kwouk, yet during this call for guards he is actually seen standing up and NOT speaking at all, meaning the voice was added later.
Bond chases Aki into Tanaka'a headquarters, where a trap is sprung for him. Afterwards, Tanaka reveals to Bond that he had been watching him on video surveillance (which made the trap easy). However, the video we see of Bond is not taken from surveillance cameras, as it has multiple camera angles, panning, and zooming. This footage was obviously shot with a movie camera, not a surveillance camera.
