National Treasure: Book of Secrets (2007)

Continuity mistake: At the end of National Treasure 1, Riley has a Ferrari 360 Spider. At the beginning of Book of Secrets, when his car is being towed away, it's a Ferrari F430 Spider. At the end of the movie, he is given back a 360 Spider.

Factual error: Ben, Abigail and Riley arrive at the Library of Congress to take the President's Book very late at night. However the Library of Congress, despite being shown as open, consistently closes at 5 PM.

Plot hole: In order for the treasure trail to be followed both desks would need to have existed in 1865 when the code was deciphered. However HMS Resolute wasn't broken up and made into desks until 1879.

Ben Gates: Before the Civil War, the states were all separate. People used to say "the United States are..." It wasn't until the war ended that people started saying "the United States is..." Under Lincoln, we became one nation.

Riley: We've broken into Buckingham Palace, stolen a page from the President's super secret book, and actually kidnapped the president of the United States. What are we going to do next, shortsheet the Pope's bed?
Ben: Well, you never know.

Patrick Gates: She fell in love with me on a treasure hunt!
Emily Appleton: That was not love. That was exitement, adrenaline, and tequila.

Question: Why does the president ask Ben to look for the page 47 of the book for him if he, as president, has access to the entire book?

Question: How does finding the treasure clear Thomas Gates of plotting Lincoln's death?

Question: Why was the playfair cipher on the missing page invisible? Thomas Gates wrote it in normal ink.
