Other mistake: When Christopher is in the bathroom stupidly "dabbing" Cathy's back as she's taking a bath there is a glass block window behind them. The window makes no sense. It doesn't match the era or architecture of the bathroom or the home, first of all, but probably more importantly - what's behind it? Where is the light coming from? It's just this random, standing glass block window with an equally-random light source. (00:34:53 - 00:56:49)
Other mistake: The skater fires two shots, one at Jade and an immediate second one at the car without reloading his weapon.
Other mistake: Just before the first arm wrestling match against "Smasher, " Bull Hurley is seen in the doorway looking at Lincoln accept a match. A few seconds later Bull seems to appear into the doorway like he is showing himself for the first time.
Other mistake: In the scene at the lake, Stennis gets down and throws Moose, who can't swim, into the water. Then he gets back up on the guard tower. Then the "Last Chance Boys" push Stennis and the tower into the water. There is a close up shot of the tower's foot. It is about a quarter of an inch from falling off the dock. If it had been in that precarious of a position, then the man's movements and getting down and back up into the seat would have made the tower fall in before it was pushed.
Other mistake: As the blond punkee pillages the bedroom for anything of value, the unseen giggling/squeaky "doll" voices prepare to attack. She is yanked to the floor by her feet, screaming, as the unseen grab her hands, then proceed to "ram" her face-first into the wall. The large blood spatters do not match the injuries to her face nor her forehead. Also, under normal circumstances, the victim would be rendered unconscious following such force. The punkee is merely a bit disheveled as the unseen toss her outside the doorway. (00:30:50 - 00:31:35)
Other mistake: When Ricky confronts the mother superior in the dining room, Ricky raises the axe above his head and brings it straight down in one single motion. Both Ricky and the mother superior are facing each other. At that angle, it would have been impossible for Ricky to decapitate her. At best her head would have been cleaved in half, but not decapitated.
Other mistake: In the scene near the end when Jackie drives the big truck through the house, there are explosions everywhere, in solid concrete, and huge sparks from tiny wires. And when did thin wood pieces like the wooden tower/pavilion outside start to explode? Nothing modern or metallic was placed on this pavilion, so that can't explain the explosions.
Other mistake: When at sea and during the crew member foc'sle rescue, the ship's crew, including Kevin Costner, are wearing ship ball caps reflecting USS Billings (BB 1369) and the BB represents "Battleship." However they are actually on a Guided Missile Destroyer "DDG 21", the USS Cochrane, as indicated by the hull number 21. (00:15:00 - 00:17:00)
Other mistake: When Eddie Sanger is saving Kathleen Riley from "Michael", he gets slashed in the chest, through his leather jacket and sweater. When they meet up the next day, he is wearing the same leather jacket. Although the front is not shown, it is the same type and colour and obviously same jacket. He doesn't seem to be the type who would wear a slashed and likely bloody leather jacket.
Suggested correction: He gets cut through the sweater only. The jacket was unzipped and does not get damaged, therefore the fact that he is wearing it a few days later is a reasonable decision.
Other mistake: When Neal checks his airline ticket it says he departs from N.Y.C. J.F.K. but the movie claims to have him flying out of LaGuardia.
