Continuity mistake: Forydize says the Tremble has a 1965 Rolex Oyster Perpetual. Q gives Tremble a replacement that is meant to be the same, but with the radio and TV screen built in - Tremble says that he cannot tell the difference between the new watch and his original. But when a closeup of the new watch is seen, it is not a 1965 Rolex Oyster Perpetual. (00:58:55 - 00:59:45)
Continuity mistake: After drinking the drugged champagne Tremble collapses the instant he enters the bathroom. But when we see him passed out against the bath he doesn't have his braces and holster on. They're hanging over the side of the bath but there was no time for him to have taken them off. (01:26:30)
Continuity mistake: When Miss Goodthighs comes in with a champagne bottle Tremble shoots and she says 'missed Mr Bond'. At this moment Tremble has no glasses. A few seconds later he says 'raise your arm' and then shoots at the bottle. He is now wearing glasses.
Revealing mistake: Mata is kidnapped and taken to Casino Royale in a flying saucer, which then releases a small hovercraft to bring her inside the island cave. Once inside the cave, the hovercraft leaves the water and goes up a ramp, at which point a tow cable can be seen pulling the hovercraft up the ramp and onto the landing platform. (01:45:25)
Continuity mistake: When Bond, Moneypenny, his daughter, and his double are escaping from their prison cell, Moneypenny and Mata Bond are barefoot. When they are outside the cell, they both have their heels. They are never shown putting their shoes back on, and they wouldn't have had enough time anyway.
Continuity mistake: When Sir James and Mata Bond infiltrate Dr. Noah's headquarters, they hurry down a corridor with dozens of doorways. There are no flashing lights, but the corridor color repeatedly changes from blue with blue doors to red with red doors from one camera shot to the next.
Continuity mistake: Most of the time that Le Chiffre is playing cards the women gathered around him are in the same position - e.g. the blonde twins are either side of him and the woman in the bright green dress is to his right. However there is one short shot, just before Le Chiffre does his levitating woman magic trick, where they are all in different positions - e.g. the woman in the green dress is now behind him to his left.
