30 Movie Franchises That Started But Never Finished
National Treasure: Book of Secrets, the follow up to the 2004’s National Treasure, was a surprising hit. The film ends on a cliffhanger, with the president handing adventurer Ben Gates the fabled “Book of Secrets” — a tome rumored to hold the answers to all the world’s best consipracy theories, with cryptic instructions to take a look at page 47. Despite promises for years that National Treasure 3 was in the works, fans have yet to discover what was on page 47. As of 2018, a script for the third film was close to being finished, but the film has not yet been green-lit.
