When Carver is talking about launching his missile into Beijing, and his motive, he says, "Oh, nothing - just exclusive broadcasting rights in China for the next hundred years." When he says "hundred years" his mouth says "fifty years", an obvious dub replacement.
120 is the maximum terminal velocity for skydivers only in the relatively thick lower atmosphere. 200 mph is indeed possible for a HALO jump. The world record is over the speed of sound. This was set by a skydiver who jumped from a balloon at 100,000 feet.
When Bond and Wai Lin are being taken to Carver's building by helicopter, we get a shot of the building itself. It has a sloped roof, and a large pole on top, making it impossible for a helicopter to land on that roof.
At the end of the film, M is informed that "Bedford reports that Carver went down with his ship. It seems that Bond made it." However, the next scene shows Bedford still looking for Bond and Lin, and thus could not report either statement to M.
The BMW that drives off the roof of the parking deck and crashes into the Avis dealer has a tinted moonroof, instead of the metal panel sunroof (with rocket launchers) seen on all previous shots of the car.
When Bond parks his car in the garage, the tires are turned slightly to the right. Later, when Carver's people try to break it open, the tires are in straight position. Also, the car is at a different angle across the space.
When Bond parachutes into the ocean, in the air the tanks are quite spread apart, almost behind each shoulder but as soon as he gets underwater, the tanks are right next to each other and The silver valves on the top of the tanks that were not there when Bond was in the air, appear out of nowhere.
When the BMW jumps out of the car park, a wide shot shows the motion of the car. If the car had continued in that motion it would not of hit the ground floor but about the first or second. Also the angle in the wide shot is different to that of the head on shot.
When Bond is fighting in the sound studio, he picks up a lampshade and uses it as a weapon. He strikes two of the henchmen with it, and never drops it, yet it has magically disappeared from his hands in the next scene.
When Stamper runs across the rooftop next to the Atlantic Hotel to watch Bond climb on the hotel's roof, the mirror-inverted letters "Atlantic Hotel" can be seen on a rooftop in the distance. That rooftop was used to film the ending of the car chase, and the "Atlantic Hotel" sign was placed there for filming, although the movie shows the parking garage attached to the hotel.
In the parking garage chase scene, when he shoots the red car with missiles it is thrown back on top of another car. The cable used to pull the car backwards from the explosion is visible at the bottom of the car while it is in the air.
When Bond tries to escape from the parking garage, you can see that the people in the car constantly cycle between no driver (presumably driven by remote control), one driver, and a driver and a passenger.
When Bond and Wai Lin arrive in Saigon by helicopter, a Thai flag is even visible flying from a building. The streets use Chinese and Thai characters, not the Latin-based Vietnamese characters. The Saigon scenes were actually filmed in Bangkok.
When the Devonshire is challenged by the Chinese early in the film, the whole point is that she is in Chinese territorial waters. When Bond parachutes in to dive to the wreck, the Americans with him are worried because she is in Vietnamese waters. She cannot be in both.
Bond is briefed in M's limousine, while they travel from the Ministry of Defence back to MI6 HQ.
The Ministry of Defence is situated at Somerset House (its real-life counter part is somewhere else), but the car can be seen driving along the Bank of England, exactly in the opposite direction to where MI6 has its base.
Helicopters are physically incapable of hovering in place with their rotors tilted forward, as indicated during the motorcycle chase. Also, we see the rotor hitting objects when in this position. Helicopter rotors are fragile. With those impacts, the rotors would fail, the helicopter would crash, pulling Bond and Wai Lin downward into a very colorful death.
The satellite in Carver's building is much too small to do anything useful, and would certainly not be on a stand that could so easily be pushed over (especially as it is stated to be worth $300m). Also, satellites are assembled in cleanroom conditions, at least Class 100,000 (ISO 8) which also requires cleanroom clothing.
The fleet as seen is missing the Royal Navy's most powerful units, the aircraft carriers, of which at least one would almost certainly have been sent along with any naval buildup. Further, none of the ships present choose to deploy their helicopters for recon or assault on the stealth ship.
It would be physically impossible for the torpedo drill, launched in the first scene, to maintain sufficient forward momentum to overcome the lateral movement of the drill that would be caused by the friction of the cutting discs on the hull of the ship.
When Bond hands the BMW to the valet in Hamburg, he tells him in German "Lass dich nicht verarschen", referring to the on-board computer's female voice. The subtitle reads "Don't let her push you around", which is inaccurate. The accurate translation would be "Don't let her take you for a ride".
In the diving scene, Bond and Wai Lin are emerging straight up out of some 30-40 meters depth, after inhaling compressed air mixture for at least 20 minutes. In real life that spells a rapid lung decompression and a certain death.
The enemy jet pilots in the opening sequence are shown sporting stubbles. While showing bad guys as unkempt gives them a more recognizable "mean" cinematic look, a clean shaven face is a necessity for fitting the oxygen mask properly.
When Bond is about to make his HALO jump from the aircraft, no one else in the cargo area is wearing an oxygen mask, which would be necessary were the aircraft depressurized at high altitude. All HALO jumps are made above 15,000 feet in altitude, well above the altitude where one could breathe without supplemental oxygen supplied under pressure.
Chinese computer keyboards do not actually have Chinese characters on the keys. China uses QWERTY keyboards just like the West. Words are typed in Pinyin (Romanized Chinese) and word processors produce characters on-screen. In reality, there's no reason Bond couldn't send his message.
When Bond and Wai Lin jump through a window through the office in Saigon, several of Carver's past headlines can be seen, in both English and German. One of the German headlines says "Gaddafi und Flug 840", referring to the Lockerbie incident in 1988. The actual flight number of the Pan Am plane destroyed by Libyan agents was 103.
At the party scene, a Porsche Boxster arrives just before Bond, the license plate reads "BYL", which is only issued to cars belonging to the Bavarian parliament - they surely have no Porsche in their fleet.
The Type 23 Duke class frigate is seen firing a missile from its forward deck to destroy the terrorist arms dealers. In reality they are equipped with Harpoon anti-shipping missiles which would be incapable of striking a land based target.
During the motorcycle chase where Bond and Wai Lin take the high route to escape their pursuers the bullets appear to be making sparks on the wooden structure (which they wouldn't do even when hitting a metallic surface). The bullet hits also follow a strangely horizontal line across the structure. With the implied rate of fire and considering the goons' firing position below the bike the bullets should stop hitting the structure after a few hits, even with low recoil.
When Bond and Wai Lin have been captured, and they are flying towards the Carver building, Bond sarcastically says that Carver has an "Edifice complex", meaning he has an obsession with imposing buildings. This is a pun on "Oedipus complex", which involves a man being secretly in love with his mother. It's a gag.
Bond has trouble operating a Chinese computer keyboard, although he has studied Oriental languages at CAMBRIDGE (see You Only Live Twice). Typing is a separate skill in addition to knowing the language, so Bond may not have this specific ability. To paraphrase Hoshi Sato on the matter: "reading a language is alot harder than speaking it." and apparently typing it.
When Carver's guards initially try to break into Bond's car, they can not even dent the vehicle; however, during the chase scene immediately after, the windows on the car shatter when the guards shoot at the vehicle. Apparently the car had a "straw to break the camel's back" point, and that was it. (Or: when Bond turned off the security system in order to enter the car, it lost this protection.)
How would the sea drill, with as much maneuverability as a hippopotamus, be able to turn corners and go upwards in the Devonshire when out of water? This seems incredible when it even needs rails when aboard the stealth ship.
Since the sinking of the Titanic, it has been mandatory that British shipping must maintain a visual watch with the use of binoculars. How is it then that the HMS Devonshire does not notice the stealth ship, clearly visible in the moonlight, just a few feet away?
There's no reason why a hotel's parking garage door should be armored and be able to withstand missiles. (It's a holdover from an earlier version of the script, where the car battle took place in the villain's headquarters.)
In the opening sequence, after firing the missile, the ship reports back that they have lost contact with the missile because it is out of range and thus it cannot be destroyed. Moments later, back at HQ, M & Co are seen watching the missile's on-board camera as it flies through the mountains towards its target. If the missile can relay images back to base, they could relay a message to the missile it to self-destruct!
After the chase, under the shower, Wai Lin opens the handcuffs with her earring in a fraction of a second. This begs the question why she didn't do so *before* the chase, like immediately after their jump through the window before they even tore down that banner, or after that on their way down to street level through the rest of that office building.
Why bother with making the Carver's ship invisible to all electronic surveillance when it is so big and bulky and has to attack an little better than point blank range that no-one could fail to see it by just looking out of a porthole?
In the video conference scene Carver is shown having requested the "new software" to be full of bugs in order to make people "doing upgrades for years". This was done to emphasize his greedy side but there would be no money in it for him. It's not a viable business practice to charge for the upgrades as it drives the customers away.
Considering that in the early 1990's, the total number of legitimate Windows licences in China stood at just 5, and given China's appalling record on keeping to its royalty deals, just how would Carver expect to enforce his deal with the Chinese general? And just how would Carver have become so successful if he is this naive?
When Bond jumps from the C-160 for the HALO jump, the scene starts with the rear hatch opening and Bond preparing to jump. The jumpmaster is briefing Bond about using his oxygen as he freefalls for 5 miles to prevent asphyxiation, yet with the hatch open at 5 miles above ground the plane is over 26000 feet in the air and over the cloud mass (as seen in a quick background edit), everyone in the back of the plane would have asphyxiated already without oxygen masks (which no one is wearing).
Assuming it works the way that Q describes it, the method that Bond steers the car with the cell phone never quite seems to match up with the direction the car actually moves in. There are even a couple of scenes where it appears Bond is not even paying attention to the car or the cell phone, and it steers perfectly.
In the opening sequence, Bond "hijacks" a military jet in an attempt to escape with the on-board nuclear bombs. As he taxis and the plane turns, the exhaust thrust overturns a truck, but doesn't even move any of the boxes or crates on the ground by it.
When Carver removes the word Killed when typing the headline and replaces it with the word Murdered the first letter is placed at the correct location despite the length of the word he is about to type being unknown.
At the end when HMS Bedford is searching for Bond and Wai Lin, a voice is heard over a loudspeaker calling "This is the HMS Bedford...". A Royal Navy ship would be referred to as "HMS Bedford" or "the Bedford" or "Bedford", but never "the HMS Bedford".
When Dr. Kaufman holds up the tape containing the news story announcing Paris Carver and Bond's death, we see that the tape is completely rewound. It was playing while Bond was in the room, and could not have been rewound so quickly before Kaufman removed it.
Wai Lin is submerged underwater for considerable time, and Bond "rescues" her by breathing air into her mouth. Bond would have exhaled ~some~ carbon dioxide, but the lungs don't process ALL the oxygen inhaled. This is why Artificial Respiration to save a drowning victim works.
Wai Lin is tied to a chain and dropped into the water below Carver's stealth ship. The chain is shown to be attached to a rafter of the ship. When the boat is blown to smithereens, the chain remains taut as Bond works to free Wai Lin underwater.
When Wai Lin and Bond are captured and brought to Carver, Carver types their obituary on a giant screen. However, he is only randomly hitting keys on his keyboard. The characters on the screen do not appear as quickly as he types, but that could be attributed to slow hardware (odd, however, for someone so powerful).
Bond knocks one of Carver's henchmen into the printing press and the newspapers start printing with blood on them. However, you can see the man safely lands in some type of basket underneath the newspapers (you can see his legs sticking out), nowhere the actual mechanical part of the printing press.
