Continuity mistake: When the children are getting ready to go to the movies and are waiting for the bus, Truck's fingers are in a cast from breaking/spraining his fingers during his fight with Tony. However after the movie, when they're getting back on the bus the cast is gone and his fingers are fine.
Continuity mistake: When the gun is telekinetically pointed at Deranian and his henchmen, Jason and the kids use this to escape and drive past both men. In the next shot, when the gun is seen still suspended in mid-air, the camper is seen right behind it.
