Revealing mistakes: When Jared is driving his car in the end, and he looks up to peek under the hood of his car's sun-blocker, you can clearly see his right eye under the bandage. Earlier it was 'taken out' by the 'driver'.
Continuity: When Jared is on the Winnebago eating the popsicle he bites the top off it and when the camera comes back to him, it is whole again. It then shows the top off it and then it becomes whole again.
Factual errors: Tom Hilts is constantly referred to as a corporal, which is an E-4 rank in the Army. However, his rank insignia on his uniform is that of an E-3 private first class.
Continuity: When exiting the truck, Marilyn puts the flask in the glove box and takes out the pistol. Later, in the restroom, she has the flask again.
Continuity: When exiting the truck Marilyn puts the pistol in the back of her shorts. When she gets to the bathroom, she pulls down her shorts without dealing with the gun that is supposedly there. It should clatter to the floor.
Continuity: When Tom goes under the yellow bus the first victim he sees has his right hand chained up in the first shot, but it is hanging straight down in the next.
