Character mistake: There is a misspelling on the cover of the issue of Forbes magazine shown in the presentation about Stark's life. It reads "Tony Stark takes reigns at 21". The correct spelling of the word is "reins". Stark may "reign" at Stark Industries but he would take over the "reins" of the company.
Character mistake: The laser pointer and the subtitle reads "Gemeinschaft Bank". That's wrong. It has to be Gemeinschaftsbank. (00:04:20)
Character mistake: The actor who played FBI agent Ross is Lennie James, who is an English actor. When they are searching for the girl in the parking garage of her building, he orders the SWAT team and other agents to search everywhere, under the cars and to "check the boots." He says this twice. Boot is the British term for trunk. He should be telling them to check the trunks of the cars, not the boots.
Character mistake: Dave's wife refers to McCall as his "Army buddy" - but the pictures in McCall's house on the shore show him to be a Marine. Not a generalisation a Marine would make.
Suggested correction: The woman didn't know better. McCall didn't correct her, as he was busy addressing her other, more egregious mistake. And anyway, it was a cover story for their service in the Agency. A proud Marine might not take that, but a spy surely does.
Character mistake: Joan Clarke pronounces the name of the mathematician Euler to rhyme with "ruler", when in fact it is pronounced "oiler."
Character mistake: The "MAC-10" machine pistol used by Darryl and Sergeant Murtough is actually a Cobray M11/9.
Character mistake: The endotracheal tube (breathing tube) was not secured to the patient. It is standard practice to secure this tube to the patient in order to keep it in place.
Character mistake: When Nedry is stealing the embryos, an extra "n" is missing on the label "Tyranosaurus".
Character mistake: After the robots first attack New York City, a series of newspapers is shown. One of the headlines in the French one reads "La Tour Eiffeil est détruite". The proper spelling is "Eiffel" (00:15:55)
Character mistake: The coroner examining Jennifer Toland's body reports that her fingers were cut off first, then the metacarpals (palm bones) were removed later. Given that when she is found her entire limb is missing up to her mid-forearm, how could he possibly tell not only that the missing part was not all removed at once, but which bits were cut off in which order?
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: Dan is supposedly such an expert in Pakistan, but he hands Ammar the cigarette pack with his left hand (unclean to Muslims, and therefore not much of a gesture of hospitality).
Character mistake: When discussing the new Pope's name (Luke) at the end of the film, Langdon says: "There have been many Marks and Johns, but never a Luke." In fact, though there have been 23 Pope Johns, there has only been one Pope Mark - reigning for 9 months in 336.
Character mistake: On Taylor's phone it says she dies at 8:32PM, but Beth says 7:32PM, when reading the message. (00:27:05)
Character mistake: About half-way into the movie the Captain asks for a fathometer reading and is told 150 fathoms. He preforms a mental calculation and says that it is 310 meters and over a thousand feet. In fact, 150 fathoms is 275 meters or 900 feet (1 fathom = 6 feet = 1.83 meters). (00:57:15 - 00:57:40)
Character mistake: During the meeting between Langdon, Sophie and Sir Teabing, Teabing refers to Scatoma as "the mind seeing what it wants to see." Scatoma refers to a partial loss of vision. He probably meant to use Pareidolia, which refers to seeing patterns that are not really there.
Character mistake: After the Lieutenant is shot and is in hospital, his CO is explaining what the GHOST system is. He explains that the acronym is "Guided High Altitude Scrambling Transmitter" - which would be GHAST. Replacing "altitude" for "orbit", which is probably what was intended, would make a Guided High Orbit Scrambling Transmitter - or the GHOST system henceforth referred to in the film. (00:06:25)
Character mistake: When Guile promises to rescue the hostages while on camera with Bison, he makes it a point to mention Charlie by name to reassure him that he wasn't forgotten. Anyone in charge of a major hostage recovery operation would avoid naming a specific hostage unknown to the enemy due to the special focus that the enemy may put on that hostage for further abuse. This was promptly proven when Bison specifically chose Charlie to transform into a beast due to Guile identifying him as a personal friend.
Character mistake: When Bond and Stacey are in the file room in San Francisco City Hall, Bond pulls out the Division of Mines Paperwork on Zorin's wells and it has "HAYWOOD" written across it. The actual fault is spelled "HAYWARD." (01:21:40)
Character mistake: When they're reviving Lindsey, Bud screams "fight" and slaps her. watch as she closes her eyes on the second slap while she is supposed to be dead.
