The Kidd here...
As soon as Stephenie Meyer's name pops up on-screen, with the accompanying TWILIGHT name, some of you are going to check out of this with the quickness.
The teaser trailer for THE HOST, an adaptation of her novel starring Saoirse Ronan, has made its debut on Yahoo! today, and, if I didn't know that what I was watching was for a coming movie, I'd have thought Visine was getting creative in their marketing campaign.
From what I can tell of the book, THE HOST is set up like INVASION OF THE BODY SNATCHERS with an alien invasion taking over Earth, except for the fact that one mind that won't allow itself to be overtaken. But you won't gather that from the teaser... only that dry eyes are bad.
