It even helped he and co-star Diane Kruger bond during filming. “We’d go and karaoke from time to time and sort of blow it out and be completely ridiculous, which helped, I think,” he said while promoting the film. “I think it was some Rage Against the Machine, AC/DC and some Sex Pistols.”

The first film’s central conceit, that there’s a secret treasure map printed on the back of the Declaration of Independence, is pretty far-fetched, but that doesn’t mean there’s nothing written on the back of the all-important American document. In completely visible ink, written upside-down near the bottom of the document, reads, “Original Declaration of Independence, dated 4th July 1776.” Why? Because before it was placed behind bullet-proof titanium at the National Archives Building, it was rolled up and carried around by the Second Continental Congress, with the text working as a label.
