Continuity mistake: In a scene towards the end of the movie, where Bond and Vesper are lying on the beach, Bond has sand on his back throughout most of the scene. When they start to kiss, in the distant shot towards the end of the scene, he has no sand on his back at all. (01:57:10)
Factual error: In the scenes at Miami Airport, you see numerous CSA planes (Czech Airlines). Czech Airlines offer no direct flights to Miami. However, Prague Airport, where this scene was shot, is full of CSA planes. (00:44:50)
Revealing mistake: During the scene at the restaurant in Montenegro (actually filmed in the Czech Republic), you see a payphone with a Czech Telecom logo on it (itself a piece of history, as these are all now rebranded O2). (01:57:50)
Continuity mistake: When Bond enters his password in the casino, he enters 836547. He later gives the password as VESPER, which on an alphanumeric keypad would be 837737. (01:07:55)
Factual error: During the chase scene in the construction site, Bond jumps down on an elevated scissor lift, hits the control box, hydraulic fluid sprays out, and the machine drops. However, all controls in a scissor lift are electric, and all the hydraulics are in the base. If you hit and broke the control box on the platform, nothing would happen other than the user would be stuck elevated until someone released the emergency lowering system on the base of the machine.
Factual error: If a house collapses into the waters of a Venice channel, after the collapse, the water would be so murky that the underwater visibility would be zero. But in the underwater scene, the visibility is like that of a swimming pool. (02:10:10)
Continuity mistake: Just after Vesper has shocked James, the lead connecting the defibrillator to the chest pad can be seen to have come loose. When the camera cuts back to James, the lead has been reconnected. Note, this is after the shock, not the disconnected lead that forms the drama. (01:33:50)
Continuity mistake: During the chase at Miami airport, the gas truck gets shot at and the rear tires blow. When Bond slides the truck to a halt, the tires are fully inflated again. (00:48:35 - 00:50:20)
Visible crew/equipment: Bond follows the girl through the streets of Venice. The camera follows him with a track shot. Bond turns left, going into some kind of alley, and the dolly keeps going. The dolly, camera, and crew are reflected in a window for a second. (02:02:10)
Revealing mistake: When James Bond is supposedly in Montenegro, this was filmed in the Czech Republic – although they changed most of the signs, they forgot some. When they are having a drink in the square, there is a visible sign saying "Bily Kun," which means "White Horse" in Czech.
Continuity mistake: When Bond is being tortured in the seatless wicker chair, in one shot when you look at the right side of Bond's face the blood is running in an unbroken line down his face. The next shot where you see his face the blood has been smudged, but in the next shot, where you see his right cheek, the blood is running unbroken again. This happens a few times in this scene. (01:51:10)
Continuity mistake: At the Poker game between Bond and Dimitrios the chips change place during shots. Most noticeable on Dimitrios' small stack (two black chip stacks and one green) in the overhead shots they are on the black line of the table carpet, in the shots from the sides, they are in between two black lines. The same is with Dimitrios' cards and his good luck token. (00:31:50)
Continuity mistake: When Bond first gets into his Aston Martin outside the Casino Royale, the driver's door is open. Then the shot cuts and the door is closed. (01:02:10)
Revealing mistake: Near the end of the movie when Bond shoots Mr. White in the leg, you can see that Mr. White is wearing knee-pads under his pants. (02:14:00)
Revealing mistake: When Bond tries to rescue Vesper from the sunken elevator you can see the stripes from the diving equipment on Vesper's face. (02:08:50)
Continuity mistake: During the scene in Miami at the Body World exhibit when Dimitri leaves the baggage tag for the second bomber the position of the baggage tag changes between shots. (00:41:20)
Revealing mistake: When Bond is chasing the terrorist through the construction site, a large pile of black pipes fall from the building. While they are falling and as they hit the ground they make all kinds of metallic clanging sounds, but when they hit the ground, you can see that they are really plastic PVC pipes, as several of the pipe ends break off and small pieces fly off them.
Factual error: When James Bond is swimming underwater, trying desperately to save the trapped Vesper, if you look, he is constantly yelling and exhaling, sending bubbles from his mouth. The problem is that this continues almost constantly for at least a full minute. Nobody has the sort of lung capacity that enables them to expel that much air and still function underwater for that long.
Continuity mistake: At the end of the scene where Bond rolls the Aston Martin, during the wide shot just as the car finishes the last roll, the windshield is still on the car. In fact you can see the windshield fall back into a "normal" position. However, when the shot changes to the close-up of Bond in the car the windshield is no longer there. (01:46:40)
Continuity mistake: When Carlos the bomber goes through the security door at Miami airport, he enters the door from a brightly lit area. We then cut to him emerging from the door - behind the door is completely dark. We then cut back to the door closing from the other side, showing that it's definitely intended to be the same door.
Answer: From the novel: "Three measures of Gordon's, one of vodka, half a measure of Kina Lillet. Shake it very well until it's ice-cold, then add a large thin slice of lemon peel."
