This seems a little unlikely, but Deadline Hollywood is reporting the following:
EXCLUSIVE: Author Stephenie Meyer, whose Twilight Saga franchise helped make Comic-Con such an important cog in movie marketing, has something dramatic planned when she and the film’s cast gather tomorrow for their final Comic-Con panel for Twilight Saga: Breaking Dawn–Part 2. I’m told that the surprise will focus on what is shaping up to be Meyers’ next film franchise, The Host. She and that film’s distributor, Open Road, will be doing something during the Twilight Saga panel. I could not confirm whether this is a sneak peek at footage–the film wrapped just weeks ago–though that would certainly make sense as the author tries to entice Twihards to embrace her next major film.
We’ll let you know what happens, but it would seem odd for Summit to let another company’s film in on its panel
