Continuity mistake: When JB is driving the white truck and is being bombed with grenades from the helicopter the truck gets smoke blackened, but when he arrives at the speedboat all the smoke marks have gone.
Continuity mistake: The train is stopped because Spectre has pushed a 1950's style Dodge truck full of flowers in the trains path. Later, when James is driving it trying to avoid the grenades dropped from a helicopter, the truck has turned into a very different looking 1961 Chevrolet truck.
Visible crew/equipment: When James Bond shoots down the helicopter then it crashes, he emerges from the rocks to run from the crash site to the right of picture, just as you see Sean Connery emerge from behind rocks from the right in the same scene. So for about a second there are two James Bonds in picture. One is the stunt man and the other is Sean Connery.
Continuity mistake: When Bond and Tatiana are in the boat chase and are being followed, they drop four cans of fuel in the sea. When Bond blows them up, there are way more than four fuel explosions in the sea.
Other mistake: When James Bond's friend Kerim Bey gets shot at the gypsy camp, look closely, he is rubbing fake blood into his own arm.
Continuity mistake: Just after Grant has hit 007 on the back of his head and knocked him out, Grant searches through the pockets of 007, he takes out some money and puts it into his lower left side pocket. But when 007 kills Grant and searches his pockets, 007 takes back the money from Grant's inside top right hand pocket.
Continuity mistake: James Bond is chased by an helicopter. When seen from above, Bond carries an attaché case in one hand; when shown from the ground, the case is in the other hand. This change happens many times, as the camera point of view switches.
Continuity mistake: When Kerim Bey is making a sniper shot towards a billboard with the rifle being steadied on Bond's shoulder, check out Bond's eyebrows - they are long in one shot, short in another....obviously painted on.
Revealing mistake: During the fight on the train between Bond and Grant, you can spot the stunt double for the Grant character by noticing the bad toupee.
Visible crew/equipment: When Bond is being led into the Bazaar in Istanbul spot the crowd being held behind a barrier.
Visible crew/equipment: In the scene where Tatiana first meets Rosa Klebb in Istanbul, the hand of a crew member is seen closing the door behind Tatiana when she enters the room (from the other side of the door - not the side Tatiana and Rosa are on).
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.
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.
Continuity mistake: When James finds the Russian defector in his hotel bed, they kiss, a lot. Problem is: At first, she's wearing a generous amount of red lipstick, and when they finish, she is still wearing a generous amount of lipstick, and it is not smudged, which it should be, and James hasn't any lipstick on his face and mouth, which should be impossible - not even a smudge.
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.
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.
Audio problem: When Rosa Klebb says to Tatiana "Romanova, the door!" in the hotel in Venice, her lips never move when she says "the door".
Continuity mistake: In the scene in the underground reservoir, Bond and Kerim set off in the little boat. There is a clip of the oar, which is turned over a few times to shake off some rats. In that clip, the oar does not move forward in the water (as can be seen from the air bubbles in the water). In the next clip the boat is moving again. A boat takes a little way to get completely still. It is implausible that Kerim would stop the boat completely to shake off the rats, and then start moving again. The clip with the rats must have been made afterwards with a stationery oar.
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).
Continuity mistake: After the scene where Klebb arrives via helicopter on Spectre island and meets Morzeny, they enter a training area and continue their conversation while walking through it. Just after Morzeny says '.we use live targets as well,' the scene cuts to a wide shot and they are entering the same training area once again, only this time from a path that is just right next to the one used before.
