Other mistake: This mistake occurs when Borden crashes Angier's act. Borden emerges from the trick door for the Transported Man trick, feigns surprise, and then "discovers" the bound and gagged double suspended above the stage. When Borden says "Ah, the Great Danton" you can see the ring and pinkie fingers on his left hand moving, even though he had already lost them by this time in the movie. We know that it has to be after the time BOTH twins lost their fingers because Olivia observed Borden's trick and says that "it is the same man" because she was fooled by both Bordens having their gloves stuffed.

1 other mistake - chronological order
Directed by: Christopher Nolan
Starring: Michael Caine, Scarlett Johansson, Christian Bale, Hugh Jackman, David Bowie
Revealing mistake: When one twin (presumably Alfred) is removing the other twin's fingers, "Alfred's" upper arm passes through his twin's head as "Alfred" reaches for the hammer. [Fixed on DVD.]
Ackerman: We'll have to dress it up a little. Disguise it. Give them enough reason to doubt it.
Trivia: The "Chinaman" in the movie was based on a real-life magician. He wasn't Asian at all, he just dressed and lived the part. The first English he ever spoke in his career were his last words. When a bullet catch went awry, he uttered the words, "My God, I've been shot" just before his death.
Question: Was Christopher Bale's character a twin or a "clone" made by Telsa's machine? (Because Bale's keyword for his diary is "TESLA" and when Hugh Jackman's character actually goes to see Tesla, he states that he knows he made a similar machine for his competitor. Bale?)
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.
