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.
