Factual error: When Bond retrieves the bombmakers's phone in Madagascar, he finds the Ellipsis message with a time code of 19:12. After tracing the origin of the message to the Ocean Club in the Bahamas, he finds the security footage of Demitrios sending the message at 19:12. But 19:12 is the local time for the Bahamas, as indicated on the surveillance tape and Demitrios' phone. Madagascar is 8 hours ahead, so the bombmaker's phone should have indicated the message was received at 3:12 a.m. Also, there is a lot of sunlight and activity going on for 3 in the morning.
Continuity mistake: When the house in Venice is collapsing - and it is shown from the outside - it moves quite fast. When it is shown from the inside it is not moving at all. Also the inside scenes last so long that based on the speed seen on the outside, the house would have been submerged long before the fight ends.
Deliberate mistake: On the roof of the sunken building, Bond tries CPR on Vesper, then quits when he realizes that she is dead and sits away from her body. Watch her right leg carefully when he returns to her body and cradles her in his arms - she flexes it upwards at the knee. Yes, I know that electrical impulses in a dead body can cause muscle movements, but this was obviously the actress involuntarily bracing herself from slipping on the slanted surface. Cut to Mr. White walking away with the money and when the camera returns to the roof, Vesper's leg is lying flat again. (02:18:00)
Other mistake: During the chase with the fuel truck at the Miami airport, Bond depresses the brakes, which apparently aren't working, and the truck rolls on. Two problems: first, after almost hitting the plane and sliding sideways, the brakes skid to a halt and you can hear air discharging from the brake system. Which brings up the second problem: since the truck is air brake equipped, there is no way it would have continued rolling if the brakes were malfunctioning. Part of the air brake system on all trucks since 1974, have a safety feature which "dynamite" the brakes if there is no air pressure in the system. This locks up the brakes with the spring brake system, making the truck stop. The truck was newer than 1974, meaning it would have had the CVSS safety braking system from the manufacturer, and would have skidded to a stop if there was no air in the system.
Continuity mistake: Near the end when Bond is following Vesper, the camera shows her from behind and then from the front, the people around her are completely different people.
Revealing mistake: Towards the beginning of the film, when Bond jumps off the van into the embassy, the patch of ground he lands on is obviously a landing mat with leaves and turf covering it.
Continuity mistake: Le Chiffre's scar on his eye changes colour, size and position during the movie. Most noticeably it is much more red and sharply drawn during the final poker game than it is in the opening scene in Uganda.
Continuity mistake: Near the start, when the Ugandan is thinking about the money, his hands are together in front of him. At first his fingertips are crossed, then in the next shot they're suddenly placed together.
Continuity mistake: The position of the Range Rover in the car alarm scene changes when Bond looks at it on the security monitor just a few seconds later.
Factual error: In the scene in which Bond is in his car after being poisoned, attempting to set up his defibrillator, the cardiac monitor at MI6 headquarters displays "ventricular tachycardia". The rapid beeping of the monitor makes this serious heart arrhythmia plausible, but the beeping then gradually slows, suggesting 2nd or 3rd degree heart block or approaching asystole (complete absence of heartbeat) rather than continued ventricular tachycardia or cardiac arrest (ventricular fibrillation). As tension mounts with his apparent impending death, the loose lead is reconnected, the defibrillator finally fires and he is saved. This sequence is not credible because defibrillation has no place in treating a slow heart rhythm, and certainly not heart block or asystole. The "correct" sequence of events should have been deterioration of ventricular tachycardia to ventricular fibrillation, and then the defibrillator shock to convert his heart back to a normal, life-saving rhythm. (01:33:05)
Deliberate mistake: When Bond performs CPR on Vesper, he isn't really blowing into her mouth. You'd be able to see her chest lift when he blows air into her lungs - even if she was dead.
Continuity mistake: When Bond shoots the guy at Praha, the bullet comes too late. You can see it.
Other mistake: When Bond retrieves Demetrios' phone, he finds the Ellipsis message he watched Demetrios send a few moments earlier. We know this must be the message he sent because it's the only message that comes up when Bond accesses the "Sent Messages" menu (indicated Demetrios deleted all prior messages). Yet the time stamp on this message is July 6 at 19:12, the same as the message sent to the bomb maker three days earlier (since the replacement bomber's phone says it's July 9). The idea that Demetrios actually hired two people for the bombing, and texted them both at the same time, doesn't make sense in the context of what the film establishes. He tells Le Chiffre he has someone else in mind to do the job, but he needs the particulars and payment. Someone already hired to do the job would already know what to do. Also, Bond watches Demetrios text the message, which is how he knows to check the phone, and the only message is Ellipsis sent to one number, which Bond later calls to find the new bomber on the street. Therefore, the timecode on the second Ellipsis message must be a mistake.
Continuity mistake: In the scene where the guy is gonna blow up the truck at Miami airport, James is caught by police and the guy looks at his phone. The time on the phone reads 2:13 yet when the guy puts the keyring on the truck and then looks at his phone again it still reads exactly the same time. (01:45:50)
Continuity mistake: After the last chip exchange, Bond's dinner jacket is off. When he gets up after winning, the jacket is back on.
Other mistake: At the end of the poker tournament Le Chiffre shows his hand first, before Bond shows his hand for dramatic effect, even though Bond had re-raised, and Le Chiffre called the raise. He should have had to have shown his hand after Bond showed his, and not before.
Continuity mistake: When Bond is fighting the contact in the restroom at the beginning, he hits the guy's hand against the mirror and the gun goes flying off to the right. After Bond drowns him in the sink and lets him fall to the ground, the gun is right under the sink. (00:02:45)
Continuity mistake: While LeChiffre is playing poker on his yacht, his girlfriend Valenka comes on the yacht after swimming. As she enters the room, she is seen passing LeChiffre twice in a closeup and wide camera shot in front of table. (00:20:00)
Visible crew/equipment: While Bond is convalescing at the lake-side recovery center from the torture scene, the Swiss banker that held the poker game winnings in escrow, comes by to have Bond enter in his PIN # to transfer funds. When he walks away, you see 2 shadows that point in opposite directions.
Revealing mistake: Bond has just stormed the embassy and taken the bomb maker as a hostage. As they walk down a hallway, the bomb maker is shot in the leg. The squib that is planted under his trouser leg is outlined.
Chosen answer: Le Chiffre operates as the banker for Mr White's entire organisation. The Ugandan is only one of many individuals and groups for whom Le Chiffre provides financial services; killing him does little to solve the problem of the missing money. Plus there's the question of trust - if Le Chiffre can't keep the money safe, then Mr White's organisation have no use for him and, as we see in the movie, will readily eliminate him. Le Chiffre's desperate to recover the money to prove his trustworthiness and save his own life.
