Continuity mistake: When Bond and Necros are fighting on the opium packages behind the plane, in the wide shot we see that Bond is all the way at the top of the bundle of packages - he takes his knife and cuts the net near his knee. In the next wide shot we see that Bond's head is above the top of the bundle of packages, but in the next close-up, packages are dropping from above Bond's head.Jacob La Cour
Character mistake: Just after Necros has infiltrated the MI5 safe house, captured General Pushkin and then escaped, M says that thanks to Necros, there are "2 dead, 2 in hospital." However, in fact Necros killed or seriously wounded 5 people, not four. First of all he kills the cook by strangling him. Then he gives the butler incredible burns on his face before knocking him out and leaving him with serious injuries. Then, as Necros walks out of the kitchen, two MI5 agents confront him with guns drawn. Necros throws a milk-bottle grenade right at their feet. This certainly either kills or seriously injures both men (a grenade at your feet is pretty devastating). Then, Necros throws another milk-bottle grenade at an MI5 agent standing on the staircase, which explodes, either killing or seriously wounding him. That is 5 agents, not 4, who Necros has seriously injured or killed, not including the milkman he also kills at the start of the scene (who may or may not be an MI5 agent).swordfish
Character mistake: When the butler surprises Necros in the kitchen, he does not conform to standard emergency radio procedures. During an emergency, the emergency code word always stands right at the beginning of the message, precisely because the reporter might go off the air before he can finish his transmission. Rightfully, the message should read something like "Intruder alert, this is three-four, intruder in the kitchen, I repeat..." Of course this would have toppled the plot to no end. (00:27:25)Doc
Audio problem: Kara asks Bond in the plane cockpit what happened to the bad guy. He replies that he got the boot. His lips don't match what he says however.
Plot hole: When Bond uses the laser on his Aston Martin to cut the police car in half, the laser supposedly cut all the way through the length of the bottom part of the car. If that's true, the brake lines would have also been cut. The top half of the car slides off when the driver applies the brakes. If the laser cut clean enough for the top half to slide off, then the brake lines were indeed cut by the laser. How could the driver apply the brakes if the brake lines were cut?
Continuity mistake: When Bond lasers through the police car, the laser is at right angles. But, in close up shots, the angle is different.
Continuity mistake: When Q is demonstrating the stun gas/explosive key ring, when Q holds the keyring it's very slim. However, when it is placed on the desk and emits the stun gas, in close up it is very thick. This is obviously to make such a slim device emit the gas (probably an under the table gag).
