National Treasure: Book of Secrets is a 2007 American action-adventure film directed by Jon Turteltaub and produced by Jerry Bruckheimer.

The film stars Nicolas Cage in the lead role, Jon Voight, Harvey Keitel, Ed Harris, Diane Kruger, Justin Bartha, Bruce Greenwood and Helen Mirren.

Thomas recognizes the message as a Playfair cipher, and translates it while Booth departs for Ford's Theatre to assassinate President Abraham Lincoln.

In the present day, famed treasure hunter Ben Gates tells Thomas' story at a Civilian Heroes conference.

Black market dealer Mitch Wilkinson produces the page fragment, with Thomas Gates' name next to those of Mary Surratt and Dr. Samuel Mudd.

Using spectral imaging, Ben discovers traces of the cipher on the diary page, that, when solved using the keyword, points to the smaller Statue of Liberty in Paris.

Ben and Abigail sneak a peek at the Buckingham Palace desk and obtain a Pre-Columbian carved plank from a secret drawer.

Ben's FBI friend, Agent Peter Sadusky, confirms the book's existence but warns that no one can read its contents without consent from the sitting President.

He found the plank in 1924, translated it, had it destroyed, and commissioned Gutzon Borglum to carve Mount Rushmore, to hide evidence of a hidden treasure nearby.

Ben ensures that Mitch receives joint credit for the discovery and clears Thomas Gates' name by proving that Booth had consulted him about the treasure, not the assassination.

[20] The group mentioned in the film as being behind the assassination of Abraham Lincoln and pursuing the city of gold, The Knights of the Golden Circle, had actually disbanded in 1863.

[22] His focus was not on preserving the Confederate States of America (CSA), but restoring slavery in neighboring countries to the south, which he wanted to make part of a proposed nation dubbed "Golden Circle.

"[22] While some members of the group would join the Confederate Army, Bickley was more focused on colonizing parts of northern Mexico as slave states.

Similarly, the clues left by Édouard Laboulaye would have been equally of no use, as the earliest models of the Statue of Liberty and all subsequent replicas were all constructed no earlier than 1875, 10 years after the end of the Civil War.

In May 2008 Jon Turteltaub confirmed that there would be additional National Treasure movies, but acknowledged that the creative team would take their time on the second sequel.
