Other mistake: Victor and Neil leave in the Rally STX van to take the boys to Moose River. Later, when Beth goes into town the license plate number is '566 241' on her Chevy pickup, but when Victor drops Neil and the boys off, we see their Rally STX has the same license plate number '566 241' as well.

Other mistake: As Jason wrestles around with the kid on his back his left eye opens some and his real eye can be seen. However, the eye was removed during the examination at the beginning.
Other mistake: The size of the town Jimmy lives in is inconsistent with the size of the population shown. The town is quite big if it has its own mall, amusement park, and a large elementary school.

Other mistake: The crew are commencing pre-flight checks, and the aircraft shown still has the blanking plates in the engine intakes.

Other mistake: While in the wooden structure in the trench, a close-up of Ciki's hands reveals that they are pristinely clean. Considering that he has been rummaging around in and out of the trench, and tending to his gunshot wound, his hands should appear at least dirty.
Other mistake: The door of the plane is open and lets in a huge amount of pressure, but suddenly, a close-up of a corner of it shows how it softly closes tightly, without anyone turning its lever, or pushing.
Other mistake: James is venturing inside the cave using his flashlight; forgetting the fact that the cave is perfectly lit and his electric torch serves no apparent purpose, it is shown casting a light on his own face despite the fact that he is pointing it forward. (00:03:50)
Other mistake: The outdoor newspaper dispenser has "The Mistleto Post" written on the side, misspelling "Mistletoe". (00:37:18)
