The technician monitoring the launch says that the satellite was launched 24 minutes ago, yet we then see a rocket stage separating, and we are told that this event is premature first stage separation. In fact the first stage of most launchers only burn for a few minutes, and the satellite would normally be in orbit within 15 minutes. The stage that is shown certainly would not have enough fuel to burn for 24 minutes.
When Plenty O'Toole comes to Bond's room, she compliments on how "super" the place is, but her mouth does not move. Later, when a half naked Plenty is yelling as she's being forced over to the window, her screaming does not match the movement of her lips.
When Bond emerges from the manhole cover in the desert, there are two men working at the site, one digging and the other watching. The dialog over the scene is not matched by the supervising worker's lips, who appears not to speak at all.
When Bond remarks that Tiffany could get 20 years to life, she responds, "20 years to life?" but halfway through her sentence, her and Bond change positions, and her mouth is not moving for the remainder of the sentence.
When Bond gets picked up from the airport and he and two other men get into the hearse, we see three doors being closed, and hear accompanying foley/sound effects for the driver side front and rear doors, but not the passenger side door.
The voice disguise machine is not realistically depicted. Such a machine would disguise the speaker's voice to the person on the other end of the phone, but in the movie it makes it seem like it is actually changing the speaker's voice.
During the craps game, Plenty throws a nine to establish the point, then immediately throws a seven, thus losing. The stick-man incorrectly says she "craps out" when the proper phrase would be she "sevens out."
When Tiffany dusts Bond's glass for fingerprints, she covers the entire glass with dust. She begins dusting it off, and it quickly cuts to the next camera shot, and the entire glass has been cleaned off already.
When James Bond gets into the back of the green van at the gas station in Las Vegas, the interior metal walls of the van are a yellow-tan color. After the trip to the Willard Whyte space facility, and when looking in at the doctor from outside of the driver's side window after he used his key card to enter the vehicle elevator, the interior walls are the same green color as the exterior of the van.
When Felix Leiter is talking to Bond at the pool at the Willard White's desert hideaway, his suit is completely dry. But when he goes down the steps, his right arm is soaked as if he reached into the pool, which he didn't. And upon entering White's "cell" a few seconds later, his arm is dry again.
When Bond is fighting Franks outside of Tiffany Case's apartment Franks swings a crowbar at Bond and it falls out of his hand when he misses. When Bond starts squirting Franks with the fire extinguisher the crowbar is back in Franks' hand.
When Bond is on the phone with Q, and Q says that Peter Franks has escaped, Bond never hangs up the phone before he leaves the room. However, in the next scene, the phone is placed properly on the hook.
When the diamond expert in the first scene after the opening credits explains the nature of the diamond smuggling operation in voiceover playing over scenes of a worker smuggling a diamond out via the on-site dentist, the speaker says the line about the industry priding itself on security twice, whether due to a script or editing error when combining multiple takes.
The "oil-rig" in Baja California which controls the laser satellite is supposed to be in the middle of the ocean. Yet when Tiffany is shown sun-bathing on the rig, we can see mountains and a coastline not too far away in the backdrop.
When Mr Wint and Mr Kidd exit the tunnel, with Mr Bond in the trunk of the car, the cover that lifts up has a Saguaro Cactus on it. That type of cactus only grow in extreme southeastern California, southern Arizona and adjoining northwestern Mexico.
You cannot make a laser out of diamonds. Even if you could, you could not make a laser out of multiple gem-quality stones; ruby lasers, for instance, are made from a single flawless rod of artificially-grown ruby.
When Tiffany takes Bond's fingerprint (fake) and compares it to Peter Franks', the two images are 100% identical, pixel by pixel. Although the two images would be similar, it would be virtually impossible to produce two 100% identical fingerprints, which are taken at the same angle, with the same amount of substrate, and the same amount of pressure applied.
Scorpions rarely sting humans, and even more rarely do scorpion stings cause death. Most scorpion stings are nonfatal. In cases that are fatal, death is not instantaneous. Scorpion venom usually takes several hours to take complete effect on the body. A scorpion is not a portable lethal injection device, as depicted in this movie.
When Tiffany Case pulls out the Polaroid of the thumbprint, she immediately peels the picture off the backing. Pulling the film out of the camera crushes a packet on the film which contained the developing chemicals. This caused the photo to develop, which took about a minute. You would then pull the photo off of the backing. There is no way that the photo could be developed the way she did it.
The laser beam destroys a Soviet/Russian submarine moving underwater. First, it's almost impossible to locate a submerged, moving submarine in the vastness of the ocean. Then the chances of a laser going through the water causing it to blow it up are extremely remote.
Shady opens the coffin, that was just in the incinerator, without releasing the catches and then grabs the lid which ought to be too hot to touch. Also, as it had just come out of the incinerator, the coffin should have been smoking.
Bond refers to the sherry he is drinking as an "unusually fine solera". A sherry produced through the solera method would be based on wines of mixed years, making it meaningless to attribute the original base vintage to a particular year. If Bond was referring to the oldest wine used in the mix, it would require an impossibly high level of discernment, as even the most expert wine tasters cannot single out vintages within a blend.
There is no such thing as a piton gun, let alone one small enough to carry as a small firearm, as we see Bond shooting a piton into the concrete supports as he negotiates the upper part of the Las Vegas building. For a single piton to support the weight of an adult, it would have to be hammered into place, by hand, taking several hundred foot pounds of energy to secure. Even if there was a piton gun large enough to carry, the required force would obliterate its target, not lodge a piece of metal into it.
Cremation furnaces run at 870-980 °C which would burn up any diamonds present (diamonds are not in fact forever); it would be impossible to successfully smuggle diamonds inside a cadaver and separate them via cremation. However, we never see the furnace at Slumber, Inc. actually operating, and cremation usually takes an hour and a half whereas Bond is given the diamonds a few minutes after the coffin moves down the belt. It is more likely that the diamonds were simply removed from the body.
...sort of. During the Las Vegas car chase scene, Bond's car ends up riding on two wheels in order to pass through a narrow alley. When the car emerges at the other end of the alley it is balancing on the opposite pair of wheels. The producers spotted this error before release, however, and inserted a quick shot to indicate that, for some reason, Bond flips the car onto its other wheels. There must have been an opening somewhere in the alley. In a TV interview director Guy Hamilton said that after he'd filmed the car coming out of the alley he was called back to England and left Albert R. Broccoli ("Cubby") to film the car going into the alley. When Guy saw the rushes he pointed out the error to Cubby who refused to do a reshoot.
When the real Peter Franks buzzes Tiffany in her apartment, she tells him to come up to the third floor. As Tiffany thinks that she has already met "Franks" (really Bond) in her apartment, there's no reason for her to remind him what floor she lives on. However, she may have recognized that this Peter Franks had a different voice and let him in assuming he was an impostor. (Though Case verifies the identities of her visitors, she does not do anything to prevent them from entering her apartment first; presumably she has a plan to deal with unwelcome guests.)
Messrs. Kidd and Wint dispose of Bond by leaving his drugged, unconscious body in a 8' section of underground pipe, open at both ends. The next day, a construction crew somehow manage to select the pipe section, hook it to a crane, lower it into position, weld it to the rest of the pipe sections, and bury it in dirt without happening to notice a man in a tuxedo apparently sleeping in it.
H.M. Secret Service goes through the trouble of providing James Bond a set of fake finger prints to match Peter Franks', but does not provide any facial disguise when all it would have taken was a photo of Franks to give Bond away.
Bert Saxby attempts to shoot Willard Whyte as per Blofelds instructions. However it was James impersonating Saxby who actually received the orders. So why did Saxby turn up with a snipers rifle at all.
When Bond is hanging from the rope at the top of the building, his arm movements are not synchronized with his upward movements. It's also noticeable that the rope he is hanging from is being pulled up through a hole in the set, rather than him pulling himself up a stationary rope.
When the construction workers open the manhole in the pipeline you can see that the hand wheel isn't connected to any kind of latching mechanism, therefore making it useless to be turning it before they open it.
In the chase scene in the desert where James Bond is being tailed by sedans, Bond makes a jump that causes one of the cars to flip and roll behind him. Once it rolls down the dune, a spare tire not matching the size or tread of the rolled car rolls into the shot for no apparent reason. The rolled car did not even lose a tire. (The wheel is in fact from the moon buggy - apparently this prop vehicle shed its wheel(s) a few times during filming.)
Despite all the broken glass in the elevator, there is no blood on either Bond or Franks. Franks even breaks the glass with his face and later grabs a large glass shard as a weapon, yet neither his face or hand is cut.
When Bond is breaking into Whyte's penthouse he fires two pitons into concrete beams, which he is then suspended from by ropes/wires. When Bond is ascending the rope attached to the second piton, the piton itself has disappeared and the rope actually passes through a hole in the concrete beam. He is obviously pretending to ascend the rope and, in reality, he is being winched up on the rope, which passes through the hole to the winch mechanism above.
During the car chase through the streets of Las Vegas, many shots plainly show crowds of onlookers obviously watching the filming of the action; they do not behave like normal pedestrians (walking, etc.), and while some sidewalks are crammed with people standing still observing the action, the adjacent sidewalks (nearer the cameras) are completely devoid of any people.
The goof items below may give away important plot points.
When Tiffany is walking towards Bond to secretly hand him the tape, a long shot of her from behind clearly shows the beginning of her butt crack protruding from her bikini bottom. The ensuing shot is a close up of her from behind slipping the tape to Bond, however her bikini bottoms are pulled fully up, no longer exposing her crack, though she made no visible effort to pull them up.
Towards the end of the film, we see a long shot of James Bond diving into the ocean that allows us to see the surrounding surface area. There is no sign of Tiffany Case who had fallen in from the same spot only moments earlier and who could not have moved away so quickly.
In the last scene, when Mr. Kidd moves to attack James Bond with the kebab skewers, he is barehanded, but when Bond douses him with alcohol, and he catches fire, he is suddenly wearing asbestos gloves.
Blofeld points out for Bond a moving dot of light on a globe: his laser satellite's position over the U.S. But the dot moves over the map at a scale speed of 20 or 30 miles per second or faster - far quicker than the practical orbital speed of about 5 mi. per second. In a later scene, as the satellite nears Washington D.C., the dot moves at a normal rate.
Tiffany recognizes Blofeld in the casino by his white cat, yet she had never seen either one before. Also, Bond hadn't seen her since he discovered Blofeld was alive and behind the diamond-smuggling operation so there was no opportunity for Bond to describe him (or the cat) to her.
The helicopters attacking Blofield's rig are merely issuing puffs of smoke, as there are no rockets in flight, either from the launch tubes or incoming onto the oil rig, and furthermore, the explosions on the oil rig are also just puffs of smoke, doing no real damage, just like the "defenses" occasionally sound like machine guns, but no barrel report or smoke is coming out.
The first target of Blofeld's laser is a nuclear missile silo in North Dakota, which is destroyed. However, even accounting for perspective, the laser is initially shown firing out of orbit, away from the Earth's surface.
For the final scene in the film, Tiffany is wearing a red and purple bikini. Miraculously, while Bond is operating the crane, Tiffany's bikini turns into a red and brown bikini. (This is only on certain prints of the film and available online clips, and is due to degradation of the film or copying from a TV showing. The current DVD and UK TV release keeps everything red and purple.)
