When Merritt first meets Daniel, Merritt tells him "I'm sensing you are a Control Freak" and Daniel replies "Have we met before?" They have indeed, and in that film, Tallahassee tells Columbus "I'm sensing you're a bit of a bitch".
The fictional Crédit Républicain de Paris, the French bank robbed in the first act, is said to be in the 9th arondissement of Paris, which is where Mélanie Laurent (who plays Alma) grew up.
All Part of the Show: Isla Fisher got into difficulty while filming the piranha tank scene. The top of the tank remained opened so that Fisher would be able to swim to the top to get some air, and there was also an emergency lever inside the tank that, if pulled, would alert the crew that she needed help. During one take, Fisher was running out of air and tried to swim to the top, but the chains on the handcuffs she was wearing got stuck on the bottom of the tank, so she was unable to swim to the top or pull the lever. She then attempted to alert the crew by hitting the glass of the tank, but since her character is supposed to be panicked and scared in the scene, the crew thought she was acting. She was stuck for 3 minutes before the stunt coordinator finally realized that something was wrong after he noticed that her handcuffs were stuck.
Billing Displacement: Jesse Eisenberg gets top billing, but Mark Ruffalo's character has the biggest amount of screentime. But then, that might just be intentional misdirection.
Fake American: Isla Fisher as Henley Reeves, born in Scotland and raised in Australia.
Older Than They Look: Jack is supposed to be in his early 20's, and likes to complain that the others don't treat him like an adult. This leads to a dressing-down from Daniel about "then it's time you start acting like one!" There is less than a year between Dave Franco and Jesse Eisenberg, and both men were in their late 20's when they shot this film.
Sleeper Hit: Industry experts were not high on the chances of this film doing great business coming on the heels of Fast & Furious 6 and opening against After Earth, a film starring Will Smith, whose last summer film not to open #1 was 1995's Bad Boys. Although Furious was expected to end Smith's opening weekend summer streak, Now You See Me exceeded expectations and also beat After Earth, tallying close to a $30 million opening weekend. Thanks to strong word-of-mouth, the film then held supremely strong over its following weeks, staying in the top three two weeks later opposite Man of Steel and This Is the End (and outperforming the two films that opened the week before) and still hanging around the top five in its fourth week against the openings of Monsters University and World War Z. By comparison, After Earth had slipped to 14th place in its 4th week, earning less than a million that weekend. Now You See Me finished with a tally over $100 million, and is Lionsgate's highest-grossing film that isn't a bookadaptation.
