The Paris Bank Heist was the first heist disguised as a magic trick that the Cavaliers pulled off. This involved sending a member of the public through a special gateway to Paris to rob a bank and bring back the money to prove the trick was real. The film’s magical debunking character Thaddeus Bradley (Morgan Freeman) did a great job of explaining how the trick was performed.
There is a real basis for the long-standing “Bank Heist” trick called “Portal“, made famous by David Copperfield. As the name suggests, the trick is to send someone from the audience to a remote location like the beach through a magical portal (shown via video recording) before bringing them back on stage.
Of course, given the closely watched nature of real-world magic, there’s no way to confirm exactly how Copperfield pulled off his turn. But over the years there have been theories.
It is generally accepted that the chosen audience members are part of the trick, rather than random spectators. “Plants”, if you will. This would allow the video to be pre-recorded, which would then make the “trick” much simpler of making a person “disappear” and “reappear” from the “portal” of the scene.
