Character mistake: On the handwritten label Bond finds, Bratislava is written Bratislavia.
Continuity mistake: When the plane crashes at the end all four engines are running at high speed, but before that all four engines had stopped because they ran out of fuel.
Continuity mistake: When the stenographer is taking Koskov's account of his escape, there is no paper in the tray and the stenographer isn't pressing the keys. Minutes later the agent/milkman enters and removes paper from the machine.
Factual error: While Bond is taxiing down the runway at the Russian airbase, he is nowhere near takeoff speed for that aircraft (if he was, the Jeep wouldn't be able to catch up).
Continuity mistake: In the teaser, there is something wrong with the landing of the second agent. He lands on a dirt road and runs to his left behind some bushes while pulling his parachute towards the ground. To his right is a rock wall. In the next shot he lands again - presumably below that rock wall. But he was running in the opposite direction. If he changed direction and jumped over the wall to the right he would have run into his parachute. And it can't be a wall behind the bushes to the left he jumped over, because you can see from the shadows that the sun comes from the low side of the wall in both shots.
Continuity mistake: When his plane runs out of fuel, Bond and Cara eject in the jeep. When the jeep ejects, the plane is just a couple meters off the ground. Cut to a shot of the plane crashing into a cliff, it's at least 10 to 20 meters up. Impossible for the plane to have gained altitude; the engines were off and no updraft of air would be strong enough to lift a plane that size.
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)
Audio problem: At the fairground, James tells Cara that he has to check a message, but his mouth doesn't move when he says this.
