National Treasure 2 di akhiri dengan beberapa tanda tanya. Salah satunya adalah tentang Books of Secret, dimana pada saat itu president meminta Gates untuk melihat Halaman 47. Sepertinya ini menjadi basis cerita National Treasure 3. Berikut informasi dari /Film quotes

“We were asked to start there [when writing the third film], so that is where we’ll start. The plan is to start from what’s on Page 47. The idea of the Book of Secrets is spectacular. It’s a great idea. The second movie sort of introduced it and used it as the center of the movie, so it is smart to make the third movie ‘okay, what treasure hunt will come out of the book of secrets’, which is kind of what the end of the movie started.”

Well, kita tunggu saja kabar terbaru dari film ini
