Those rabid fans of The Twilight Saga: Breaking Dawn - Part 2 have been camped out in front of Hall H for days, just to see the latest sneak peek at the franchise finale, based on author Stephanie Meyer's blockbuster book series. Today we have word that the author is planning a special surprise at tomorrow's panel, involving the Open Road Films adaptation of her latest novel, The Host.

Stephanie Meyer is scheduled to appear at the Hall H panel on Thursday, July 12 at 12:45 PM, and it is said the author plans on unveiling some sort of surprise for her loyal fans. It isn't quite clear what that surprise will be yet, whether it be the first footage or, perhaps, an appearance by The Host star Saoirse Ronan. Production recently wrapped on The Host just a few weeks ago, so it is possible that the editors could whip up a reel of footage in time.

The Host is set in a futuristic world where aliens dubbed Souls have infiltrated the human race, with their ability to inject themselves into human hosts and take over their minds and bodies. Saoirse Ronan stars as Melanie Stryder, one of the few left on Earth who haven't been inhabited by this alien race, until she meets Wanderer, a soul who takes over but begins to identify with her.

Stay tuned for any updates regarding this secret surprise tomorrow at San Diego Comic-Con 2012.
