Continuity mistake: Hugh Jackman puts a tan vest on twice in the scene when we first meet his wife.
Continuity mistake: When the hotel clerk show Angier Tesla's machine in its box, he has his hands behind his back, and then moves them in front of his body. Yet when the camera cuts to behind the clerk, his hands are still held behind him.






Answer: They were twins. Tesla didn't make a matching machine for Borden - all he made for the twins was a machine that made some light and noise to enhance their trick. The Borden brothers sent Angier off to see Tesla on what they thought would be a wild goose chase, just to get him out of the way for a while - they would never actually give away the real secret to their trick. They never anticipated that Tesla could actually have built the machine in question.
