In the Continuing Pursuit of Fake Truth
Except that the entire story takes place in a 12-hour period, no plot details have been released, and I'm not even sure if Tom Hanks is signed on (though, I'm sure he is). It will probably be based on a bullshit conspiracy theory. In fact, here's hoping that the next Dan Brown movie can be a crossover with the National Treasure franchise. Tom Hanks' and Nicolas Cages' bad hair in one movie! It'd be like Christmas at rattyfuckinghair.com.
