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: As we see when Borden goes down under the stage to try to learn how the trick is performed, the tank is already in place before the machine is activated. Angier is using a large number of identical tanks, which is probably one of the deciding factors in only performing the trick a limited number of times.
