Character mistake: Jim Sturgess uses a sentence that contains the word 'me'. He is corrected, being told that the word 'I' would have been correct. However, he was grammatically correct in his use of the word 'me'. The correction was in error.
Character mistake: It is highly unlikely that the recipient of Mr. Butler's application for the professorship position would not only call him so soon, but ask him to come to her office right away (where she would humiliate him for the things he wrote in his essay on "qualities that make me a good teacher"). Moreover, her failure to listen to Mr. Butler and give due consideration to his assertion that someone else actually wrote those offensive things showed poor judgment, especially since she knew the person who referred Mr. Butler and spoke highly of him. Someone tampering with his application would make more sense than believing that Mr. Butler actually wrote those things that criticized the very college he was applying to and boasted so much about himself. That Mr. Butler was not able to say more to make his point believable is also problematic. He is an English teacher, so should have the vocabulary and mastering of techniques to make a convincing argument, but he failed to defend himself.
Character mistake: Once Santino and Ares find John again in the hall of mirrors, John is fighting two of the grunt men that came in with Ares and kills them. Both of which had light assault rifles and weapons on them. John and Ares proceed to empty their pistols out at each other before she runs off with Santino. John then throws his empty pistol away and gets up to pursue his target unarmed and while limping. It is unreasonable to think that someone with his skill and training and experience would not take two seconds to reach down and pick up one of the guns dropped by the two men he just killed before chasing after his target, especially given the highly trained body guard with him accompanying his target. As well as probable encounters with more grunts. To add to this, he was seen doing just this moments before when he had limited ammo and each time he'd down a few enemies he would pick up one of their guns and continue. (01:41:30)
Character mistake: At the beginning of the film, the officer states that the kid taken was named Jeremy Jenner, when he was in fact named Darius Jenner.
Character mistake: Aunt Dottie, pointing to Will's Range Rover, said, "You're not taking that thing out tomorrow, are you? That thing's gonna get stuck before you can get started. You take the Ridgeline. That'll handle anything up there [mountains]." A Range Rover has great capability in all types of terrain and is rated as one of the best off-road SUV's - more than can be said for the Honda Ridgeline. (The movie is not classified as a comedy).

Character mistake: This ship's computer, 'mother', says "declention" instead of "declination" when giving coordinates of the planet.
Character mistake: In the highlighted newspaper article entitled 'DeFeo Son Accused' about the killings, the first sentence of the article ends with two periods. Also, in the 3rd sentence, the word 'psychiatric' is spelled "psuchiatric" with a 'u' instead of a 'y'. (00:01:05)
Character mistake: King George VI got out of car in admiral's uniform without his cap and saluted another officer. RN officers do not salute without their caps.
Character mistake: Set in Texas, the Sheriff threatens the wrongdoer with the gas chamber. Executions in Texas at that time were all by electrocution, namely by "Old Sparky," the electric chair. Texas has never used the gas chamber for executions.
Character mistake: When we see the relative positions Eddie and Johnny have, Eddie appears to be the one that should have done the signaling to the patrol car instead. (00:55:40)
Character mistake: Toni Collette tells XXX that their plane has "Fuel tanks big enough to circumnavigate the globe three times without ever landing." The plane is a Boeing C-17 Globemaster III, which while having remarkable tanks, can go for 5,200 nautical miles, around 10 thousand km, 1/4 of circumnavigating it once. Even if someone made a tank 'big enough' to back the bragging of the snotty CIA boss, it would weigh so much that it'd be impossible to take off (and consume a lot more fuel too), which is why you can refuel that plane in the air.
Character mistake: Although Henry borrowed two books on crime scene investigation from the used book store, he obviously did not learn enough, especially about forensic science. For example, shooting from the tree house could be determined by the location/slant of the bullet in Glenn's head/body, and cutting off tree branches that would obstruct the line of fire could be evidence of pre-meditation. Henry may have thought he planned the perfect murder, but it was far from that. (00:30:30)
