Other mistake: When the crew is isolating the boiler in the Pendelton, the pipe wrench on the isolating valve is on backwards for the direction it is being turned.
Other mistake: Kevin Costner is billed in the credits as "Jerico Stewart." His prison file though spells his name everywhere as "Jerico Steward", with a D. (00:12:00)
Other mistake: The movie poster shows a reflection of a $100 bill on the lenses. The bill should be flipped.
Suggested correction: Since this isn't part of a scene in the movie, it's not a mistake. It's just a stylized image. It would be no different from pointing out a group of people superimposed over each other or appearing larger than big objects they're next to.
Other mistake: When Rafe arrives at the new school, principal Dwight has his arms full of items he confiscated when the morning has not even started yet, very specific and obvious rule-breakers like a skate, 2 footballs and a basketball. So did some dudes just start playing ball and shooting hoops in front of the principal at 8 am in the middle of the street? Who are those rebels? There's no trace of rule defiance early in the movie.
