5) What Was On Page 47? – National Treasure 2: Book Of Secrets
Despite being pretty dopey and lightweight, there appears to be a lot of love for the National Treasure movies, and talk of a third film crops up from time to time. It seems unlikely to be a direct sequel, though, since it’s been nearly a decade since Book of Secrets and Nicolas Cage’s star has fallen a good deal since then.
The second film revolved around the titular book that contained info on major government secrets like Area 51 and the JFK assassination. The ending features the president confronting Cage’s hero about “Page 47” of the book, which is apparently “life-altering.” This coy tease was clearly setting up a third adventure, but Disney has bigger franchises to fry, so National Treasure is currently stuck in development hell.
