Other mistake: When Jack is using the chainsaw to dig Burt out of the Graboid, we do not see where he is cutting, but we do see sparks fly just before he stops and puts the saw down. The chainsaw angle does not match the sparks' direction.
Other mistake: The outdoor newspaper dispenser has "The Mistleto Post" written on the side, misspelling "Mistletoe". (00:37:18)
Other mistake: After Luis finishes shooting Billy, Bonny goes from being in the first door frame to leaning in the second door frame where Luis just was to being in the middle of the room.
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: When Dos is killed by his own grenade (after he dropped it) the direction the explosion sends him makes no sense. He should have been facing the other direction. (00:52:33)
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: 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. (00:30:40 - 00:36:40)
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. Yet combined with the kids and adults seen, there couldn't be more than a hundred people living in this town.
Other mistake: In the end credits, Michael Andretti's name is spelled as "Micheal".
