Bond's tie can be seen changing positions while in mid conversation when Draco and Tracy drop him off in front of Gumbold's office building. Bond's neck tie can be see tucked inside his coat, then dangling in the next shot, then tucked back inside his coat.
Just after we see the train for the first time in the Swiss ski resort, a man with blond hair is reading the Daily Express. On the back page, the headline is 'Why Brown had to go' and above this is written 'Stock steps in at Luton'. Allan Brown was fired as manager of Luton Town FC on 17th December 1968 and Alec Stock was appointed to the position three days later. However, the three letters we see Bond photo stating in Gumbold's office in Bern are dated 12th June, 30th July and 3rd August 1969. Therefore, the newspaper being read in Switzerland may have been dated one year or more prior to the date we could suppose that we are observing the man reading it.
In the first fight scene on the beach, Bond is fighting the attacker with one glove on his hand. Bond knocks him to the ground. The attacker picks up his gun, but Bond kicks it out of his hand, and it goes flying. It plays the sound effect of the gun being fired, after the gun has already been kicked out of the attacker's hand into mid-air.
After the fight at the beach near the beginning of the film, the girl leaves Bond and he says "This never happened to the other fellow." His mouth appears to be saying something completely different for this line.
When the skier falls into the snow-blower, there's some poor editing. The blood and guts seem to start coming out of the snow-blower before the man even falls into it, and his screaming continues to be heard after he is dead.
When the Saint Bernard arrives, Bond says, "Never mind that, go and get the brandy!" Bond's mouth does not match his words. Also, Bond and the dog change positions a couple times before Bond finishes his sentence, but Bond's words are unbroken.
An allergy is not a feeling of disgust or revulsion towards something as described in the book and movie - it is an immune system reaction which can be fatal in some people. Eating the food you are allergic to would still cause the reaction, even if you had already been hypnotized beforehand to believe you enjoyed it. Ruby and the other girls don't understand this.
Bond, disguised as Sir Hilary, explains that there are thirteen officers in the Royal College of Arms, which is correct. However, as Sable Basilisk (Sir Hilary's title) is a fictional office, Bond should have said fourteen officers.
During the distant view of the helicopter assault on Piz Gloria towards the end of the film, a helicopter that is slowly approaching the building at the far right of the screen (widescreen DVD version), suddenly vanishes into thin air and then reappears as a landed 'copter just one second later.
After Irma Bunt sees the girls off in the van, a car with 3 Blofeld henchmen pulls up. They honk to her and the man riding shotgun gets out and lets her into the front passenger seat. He gets in the back. But in the next shot of the car's occupants, Bunt is in the back with a man to her left and one in front of her.
When Bond is locked in the cable car machinery room, the cable car travels down and is shown stopping at the support tower, but the next shot shows the car at the base station (note PRIVAT ENTRITT VERBOTEN sign). The car then leaves the tower and arrives at the base station again.
When Bond is first summoned from the dinner to meet with Blofeld in his office, Gruther assists him in putting on his overcoat. Bond puts both arms in the sleeves but when he arrives at the office he is wearing the coat draped over his shoulders as can clearly be seen as Grunther slips it off.
When Bond is talking to Tracy at the beginning in the casino restaurant, Tracy is resting her chin on her hand. When she says, "People who want to stay alive play it safe," she lowers her hand and leans forward. The shot changes and she is resting her chin on her hand again without having time to return to that position.
During the attack on the Piz Gloria, one of the scientists throws a large beaker at a glass double-door before Bond gets to it, splattering a purple liquid across both doors near the handles. The next shot shows a close-up with a large hole burned through the left glass door at head level surrounded by gray char marks as Bond walks through the opened right door. The next shot has Bond through the doors, which are closed, intact and clean.
As Bond clears out his desk, we see Honeychile's knife from Dr. No, Grant's garrote/watch from From Russia with Love, and a re-breather from Thunderball, with appropriate musical cues for each. The first item would have been lost or destroyed in Dr. No's time frame. The filmmakers knew this fact, and chose to ignore it in order to "bridge" the Bond movies through the lead actor change.
During the ski chase Bond is pursued closely by three men, two of whom are armed with rifles and one (Gunther) who has only a holstered pistol and ski poles. Towards the end of the ski chase, one of these three skiers flies into a tree about ten feet from the ground and falls in a heap. Gunther calls him an idiot. However, the fallen skier was dressed as Gunther, wearing a pistol and carrying only poles. When the remaining two men follow Bond off a jump, both carrying rifles. However, when they land, only one has a rifle. At this point Gunther crashes into another tree, still carrying only ski poles.
During the stock car race, when the Mercedes enters the track, it fishtails and hits Mini #11, which has spun out and stopped. A few seconds later, the Cougar passes a moving #11. The Mercedes then hits #11, causing it to spin; in the next shot, #11 is still in the race and is passed by the Cougar again. A few seconds later, after the white car flips, the Cougar passes #11 a third and final time.
When Bond fights the third attacker on the beach, the man approaches Bond with a knife in his hand. It then cuts to a camera angle of the man throwing a punch at Bond, and you can clearly see he is carrying no knife. Bond flips him onto the sand. When it goes to the camera shot of the man on the ground, you can see the knife is back in his hand again.
When the fourth attacker approaches Bond on the beach, he picks up a grappling hook. The grappling hook is facing towards the right on the ground. The camera cuts away quickly and cuts back, and then when the man picks up the hook, it is facing towards the left.
When Tracy is fighting off her kidnappers, one of them gets a piece of the trellis stuck to his head, and then he falls down the stairs. As he is falling down the stairs, you can see that the piece that got stuck to his head has disappeared.
When Bond is escorted to Draco's office in the Rolls Royce you can see that the tarpaulin covering the electric folding top is in place. A few moments later the folding top is being closed. This is only possible if the tarpaulin is removed before.
During the helicopter assault on Piz Gloria one of the commandos throws a grenade landing on the veranda. He throws it underarm an impossible distance and directly through the helicopters rotor blades.
Blofeld fails to recognize Bond, even though the two met face-to-face in the previous film, You Only Live Twice. (The original script for OHMSS began with Bond having his face altered via plastic surgery to explain the change of actors. This idea was dropped, but in doing so it created this continuity error later in the film.) Perhaps he is merely toying with Bond, feigning ignorance in a cat-and-mouse game.
During the stock car scene, when one car gets flipped, there is an in-car POV from the upside-down stock car. However, one can see that the shot is really a conventional reaction shot of the driver inverted in the editing room by the fact that the background and spectators are also upside-down.
When the three helicopters are attacking the Piz Gloria and are about to land pay attention to the helicopter on the far right. It fades out and fades back in again on the landing pad. At the same time on the left side a helicopter fades in.
When Bond stops his car overlooking the beach, he uses a scope to get a better view of Tracy entering the sea. A number of shots follow showing the view through the scope however you can see outside of the outline of the scope and it is clear that the whole image is the same and the scope outline was added later.
During the raid on Piz Gloria, Bond seems to shoot one of the scientists straight through a plate glass door, yet, there is no hole in the glass and it does not shatter or break or anything. It is also quite obvious that nothing comes out of the gun.
When the bomb goes off that destroys Piz Gloria, Draco counts down the timer, 5, 4, 3, 2, 1, 0. The bomb does not go off for a full 9 seconds after Draco counts "zero" allowing Bond and Blofeld enough time to make their escape before the explosion.
At the wedding, Draco and M discuss an occasion where M's department cost Draco three men. M says, "Ah, yes, November 1964 - the bullion job." This seems to be a reference to Goldfinger, implying Draco was once in league with Auric Goldfinger. But if the writers intended this, they made wrong allusions: 1) M alluded to Draco getting away with a large portion of the job while nothing was stolen; and 2) it's cold in Kentucky by November yet Goldfinger's battle was filmed with obvious summer scenery.
When Bond throws Blofeld off the bobsled, Blofeld's head gets stuck in the tree, in the "fork" in between two branches on the tree. The camera cuts to the next shot, and Blofeld's body is hanging from a different position on the main trunk of the tree.
During the final scene in the car, when Bond and Tracy are talking, Tracy's position in her seat changes several times very rapidly. It alternates between one position where she is close to Bond and her elbow is raised, and another position where she is further away from Bond and her elbow is lower.
When Bond goes in to wake up Ruby, it is actually Irma Bunt hiding in Bond's bed, disguised as Ruby. However, you can tell the original was the real Ruby and they switched actresses, because of the facial appearance, hair color, voice, and everything else.
