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.]
The Prestige (2006)
1 revealing mistake - chronological order
Directed by: Christopher Nolan
Starring: Michael Caine, Scarlett Johansson, Christian Bale, Hugh Jackman, David Bowie
Continuity mistake: Hugh Jackman puts a tan vest on twice in the scene when we first meet his wife.
Alfred Borden: Everything's going to be all right, because I love you very much.
Sarah: Say it again.
Alfred Borden: I love you.
Sarah: Not today.
Alfred Borden: What do you mean?
Sarah: Well some days it's not true. Maybe today you're more in love with magic. I like being able to tell the difference, it makes the days it is true mean something.
Trivia: During Borden's performance which ends with Angier shooting him, on at least two occasions the bill for the show can be seen off to one side. About halfway down is the name "Harry Dresden", the name of the wizard protagonist from the Dresden Files book series by Jim Butcher.
Question: When Borden and Fallon are in the same scene, is someone else playing Fallon? Or does Christian Bale play both, the same way Arnie Hammer did on Social Network?
Answer: It's Bale, at least whenever you can see Fallon's face. The same way they do twins played by the same person in any other film.
