When DuBois forces Solo and Kuryakin to help him escape he uses a revolver. When they arrive at his daughter's home the gun has changed to an automatic.
During the Prologue car chase and the chase at beginning of Act I the three-pointed star hood ornament on the Mercedes Ilya is driving is clearly visible from camera shots inside and outside the car. Midway through the second chase it disappears, again from both angles. Then it reappears again.
When Napoleon disables the coughing guard he is standing about six feet away from the door into the missile room. When the camera view changes from inside the room, the guard is suddenly down at the other end of the hallway.
In Act IV Solo shoots at 2 door-knobs, but there is no damage to the knobs or the doors.
Ilya incapacitates the 2 hunters. The first one is pushed and left flailing in the water. Illya then knocks out the second hunter and pushes him into the water. The first hunter, who has just proven he can indeed swim, is now gone, when he should have still posed a threat to Kuryakin.
When about to be branded with the hot iron, Solo reads the letters (right to left). The letters should have been reversed.
When Solo is rigging the cell door to shock the guard he sticks the two wires in outside the light socket where no electrical contact would be, only the insulated outer casing.
When Solo is unscrewing the light bulb to rig the cell door to shock the guard the printing on the bulb says "60 watts 120 volts". But France has 240 volt line current and that bulb would blow out immediately when power was applied.
At the very beginning of Act I, Illya starts driving the car with the gear shift lever at about the one o'clock position, which is generally where the Park position is located.
When Ilya and Vogler are having their archery contest they are shooting at a wooden sign. At one point Ilya tosses a box of matches to the man standing by the sign meaning the target couldn't have been more than few feet away.
Robespierre threatens to kill Kuryakin, but Illya prevents himself from being killed by threatening to destroy the missile component. Robespierre counters by telling Illya that he'll send his guards to kill Solo. Kuryakin gives himself up, when he could have still threatened to destroy the component.
When Solo asks Robspierre what he knew about "inertial navigation" he proved he knew nothing by stating it used the stars to navigate. That would be "celestial navigation".
The hot branding iron has the letters "LEF" on it but they should be in mirror image to leave "LEF" on whatever is branded.
