Continuity mistake: When Billy Magic [Kevin Bacon] was backing into a parking space and stopped, the driver's side tires on his Cadillac were touching the white divider line. Seconds later when he was getting out of the Cadillac, the car/tires were more centered in the parking space (i.e, the left tires were no longer close to the white divider line). (00:14:50)
Continuity mistake: There's Fall foliage at the beginning of the movie and when Bokky [Bill Paxton] and Pat [Mark Wahlberg] are leaving the camp grounds but, after they drive away, the foliage is Summer-like (and varies thereafter). (00:19:50)
Continuity mistake: When Sam walks into his kitchen at the beginning after cleaning his driveway, he walks past his son. His son goes from having his right hand down on the counter to up, holding a ladle between cuts.
