Plot hole: Bond lies to Tanya on the date the embassy would be bombed (Karim and Bond knew the 13th) and Tanya denoted the deception by telling Bond when he came in the decoding room she thought it was the 14th. How did Grant know to A: be on the train and B: have an entire escape plan set up for the wrong day?
Revealing mistake: When Bond kills Red Grant in the train compartment by strangling him with his own garrote wire, the final shot reveals that the garrote is missing and Bond is faking it.
Continuity mistake: Just before the girl fight at the gypsy camp, Bond's coffee cup moves between shots. In the first clip after we see the girls enter the scene, the withe rimmed coffee cup is at the corner of the table, to the left of Bond's plate. In the next clip is is right next to the coffee pot and the plate. In the clip in between, Bond sits perfectly still, and the cup is visible, so it was not moved there. (00:41:40)
Continuity mistake: During the battle at the Gypsy camp, Kerim Bey gets shot on his arm but when Bond talks to him later, he has blood everywhere. Even if he had blood on his hands, I don't think he started to touch himself everywhere just for the fun. (00:45:20)
Continuity mistake: When 007 pulls the gun out on Grant, watch how Grant's shadow changes position in the background in between shots, from when he says "take it easy 007" to his next line "my escape route's only for one"
Continuity mistake: When 007 puts Tatiana into the back of the truck with the flowers, he also puts his own attache case and the lector into the back of the truck: But later, when he stops the truck and gets out, he can be seen holding part of the rifle that he will use to shoot down the helicopter, then in the next shot he is carrying the lector from the truck again.
Factual error: In the scene where James Bond is being given his "gadgets", Q points out that his rifle is an "AR-7 in .25 caliber". The AR-7 is a real rifle, but is only available in .22 Long Rifle caliber. Due to numerous design features, especially the screw-off barrel, it can't be made to fire a .25 caliber cartridge of any type. (00:22:05)
Continuity mistake: In the boat chase scene, when the bullets hit the drums on the back of Bond's boat they hit the ends of the drums. In order for that to happen one of the chasing boats would have to be alongside of Bond's boat. At no time are any of the chase boats shown to be that close.
Continuity mistake: In the boat chase scene, when Bond fires the first flare he is on the right side of the boat. In the next shot (from far away) he is on the left side, and the very next close up shot he is back on the right side.
Continuity mistake: During the fight at the gypsy camp, just before the host thanks 007 for saving his life from the gunman up above, watch carefully at the point when he is aiming his rifle and about to shoot. In the next shot just before 007 fires his gun, you can see the gunman loading his rifle. (00:44:15)
Continuity mistake: Watch the black Citroen Traction Avant saloon car that the Soviet spies are driving/tailing Bond and Kerim Bey's son in. When we first see it (at the airport), the hubcaps are gray and flat. When you see it through the rear window of Kerim's son's Rolls-Royce, you can catch glimpses of the hubcaps being cream-colored (which is how the Traction Avant came from the factory). However, when SPECTRE agent Donald Grant conks the Soviet agent over the head, from that point onward, the hubcaps are black (such as when he parks the car alongside Kerim's Rolls-Royce). (00:24:15)
Continuity mistake: When Bond is in the gypsy camp, the two girls Vida and Zora, who are about to fight over a man, are coming out of a caravan both wearing long skirts and scarves. When they each take their scarf to bind it around their hips, the skirts have suddenly disappeared without ever being taken off. (00:41:35)
Factual error: Krebb's "reading" glasses are strongly concave. If she really needed them to read, she wouldn't be able to walk safely without even stronger concave spectacles and she certainly wouldn't be able to see anything more than a metre away. Real reading glasses are convex. (00:15:35)
Continuity mistake: When the gypsy girls start their fight they both have perfectly clean hair. A few seconds later they both have bits of straw in their hair, although neither of them has fallen onto the ground yet. (00:41:55)
Continuity mistake: As the destroyed helicopter falls, it first falls straight and smooth. Then the wreckage is twisting, and finally on the ground. As the wreckage is on the ground, there is no indication that it has just hit, as indicated by the off-screen noise, and the explosions are on an already settled prop set up for the stunt.
Continuity mistake: When James encounters Tatiana for the first time in the bedroom of the hotel bridal suite, as he begins to sit on the edge of the bed he is holding his Walther in a non threatening position in the palm of his hand, with his thumb on top of the slide. As the scene cuts to the POV of Tatiana, the pistol is being held in a firing position, finger on the trigger, and switches back when the scene cuts back to the wide shot of both of them. Also when Tatiana reaches to move the gun away from pointing at her and says "Guns upset me" she returns her hand to beside her on the bed. At the cut to the wide scene, she is again moving the gun away. (00:53:45)
Continuity mistake: In the chess game, when Kronstein has moved the queen, and we see a closeup of the large wall board, where the queen is moved - in the next clip when we see the wide shot of the room, the queen has not yet been moved. (00:06:50)
Continuity mistake: When Bond and the others board the train in Istanbul, they board the train at the rear which shows passenger coaches. When the train does not stop at the scheduled rendezvous because Kerim has been killed, the passing rear of the train contains freight cars. When Bond and Tatiana escape from the train, the departing shot of the rear of the train shows passenger cars again. (01:04:40 - 01:13:05)
Revealing mistake: When James Bond opens the water to take his bath, there's only water vapor coming out of the faucet.
Visible crew/equipment: Near the end, where Klebb and the man who played chess are standing in front of Blofeld, a man with a poisonous knife sticking out of the end of his shoe kills someone. Just before he does, the cameraman's shadow can be seen on his shirt.
