Continuity mistake: In a hotel room at the start, Bond finds Ronson bleeding. Note the amount of blood on his chin coming from his mouth. In the shot where Bond opens Ronsons's jacket partway to see the blood, there are a bit of dripping blood going down his chin. In the shot where Bond leaves the room, there is suddenly a huge blob of blood on the left side of the Ronson's lips that wasn't there before.
Deliberate mistake: When Bond walks through the tube train he leaves the doors open so the cameraman can follow him. This scene was shot several times to get the front and rear shots. When filming from the front, he closes the doors behind him.
Visible crew/equipment: After Patrice jumps onto the train, Bond drives off the bridge and lands on the train and begins to fall over the side, then climbs back on. Eve then says "They're on the train." During this shot, you can see the white platform Bond was standing on to climb back onto the train.
Factual error: In Turkey the first two numbers of a vehicle licence plate belong to a city. Number 34, for example, is for Istanbul. The motorcycle chase in the beginning of the movie takes part in Istanbul (both the Land Rover and the Audi have "34" plates). However, once they come to the bridge where Bond jumps to the train, all the vehicles on the bridge (except the Land Rover) have plates starting with "01", which is the licence plate number for the city of Adana, where those scenes were shot.
Factual error: It would be impossible to drive a silver Aston Martin DB5 from London to Scotland without getting splash marks on the side of the vehicle. Especially in view of the fact that the road conditions are wet by the time 007 and M reach the Scottish Highlands, but the car still looks immaculate.
Factual error: On the District line, Temple and Embankment stations do not have two platforms between each train. They actually run side by side, and not with the platforms in between the two trains.
Factual error: When Bond climbs up from under lift/elevator after hanging under the assassin's lift car he opens adjacent lift/elevator landing doors just by pulling them apart. This is not possible without first disengaging the door lock mechanism, which is operated when car is at that level. If this were possible anyone could push lift/elevator doors open from any level and fall down the shaft.
Continuity mistake: Just after Bond has lost track of Silva in the London Underground station, the scene cuts to M's parliament meeting. At this time, the time on M's watch reads 3:00. Yet when Bond catches up with Silva in the basement of the London Underground station, the time on Bond's watch reads 4:55. Far too long to have passed given the events seen and distances travelled.
Other mistake: In the opening scene where Moneypenny is holding the rifle, you can see the flash suppressor was installed upside down. The 'slots' are on the bottom.
Continuity mistake: In the courtroom shoot out scene, Bond shoots two fire extinguishers to use as a smokescreen. If you watch Eve as he steps out, she lowers her weapon dramatically at the last second. When the camera cuts to her immediately after, her gun is raised again.
Factual error: The Ambulances used in the film in the "M" attack in London are incorrect, as they are not the current vehicles used by London ambulance service. They all now have the patient lifts on the rear. Various vehicle tax discs were out of date too.
