At the very beginning, David sits in front of his newest drawing, showing a man with two guns, a rose right of him and a tower far behind on the left side. This drawing shows Roland, a character out of "The Dark Tower", a well-known series of books from Stephen King. This drawing is shown again, some time later after the storm, and David tells that this drawing was meant to become a film poster.

During the scene when the monsters enter the store, watch for when the man on fire stumbles into a book rack. All of the books are Stephen King novels.
