I was surprisingly a huge fan of National Treasure. It was a fun no-brainer, sit-back-relax and enjoy popcorn film. And while the whole idea seems to be “borrowed” from The Da Vinci Code, It did everything right that The Da Vinci Code adaptation did wrong. And now we have the teaser trailer for National Treasure II: Book of Secrets, which follows the mystery of the eighteen missing pages from John Wilkes Booth diary. It looks like a fun follow-up. Check out the trailer after the jump.
