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: 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: When Jamie is first speaking to Aurelia, he says "molto bueno", which the housekeeper woman tells him is Spanish. 'Molto' is actually Italian. (00:38:30)

Character mistake: When the Japanese attack is imminent, a soldier loads the 50 caliber machine gun rounds into the box backwards, with the rounds facing the gunner.

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: While he is describing his origin, Dr. Manhattan mentions a circulatory system appearing at a military base. However, what is actually shown is a nervous system, as it depicts a brain and spinal cord.

Character mistake: When Barry Lyndon is talking to his mother privately, while standing on the bridge overlooking the water, Barry's mother refers to Barry's son Brian as being "at the mercy of his stepbrother", meaning Lord Bullingdon. They have the same mother. Lord Bullingdon and Brian would be half brothers, not step brothers.

Character mistake: When Malloy first visits Frannie in her apartment, he says the girl was killed on the 15th, but when Frannie is in the cop car for the first time, Malloy's partner says it was the 11th.

Character mistake: Joan Clarke pronounces the name of the mathematician Euler to rhyme with "ruler", when in fact it is pronounced "oiler."

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: When Vivian is in the tub singing "KISS" by Prince, she sings the verses in the wrong order. Not a big mistake, but a noticeable one for a Prince fan.

Character mistake: Amanda's lawyer says several times she'll go to the gas chamber if found guilty - once to her, once to the prosecutor and once to the jury. Oklahoma doesn't use, and never has used, the gas chamber for executions. (00:15:00 - 01:16:00)

Character mistake: In the scene when Dave is checking out the failed transmitter at the radio station, Dave says "the bad news is your return loss - way too high". This is a mistake, as the movie makers got confused between the terms "return loss" and "insertion loss". Dave should have correctly said either "your return loss - way too low" or "your insertion loss - way too high".

Character mistake: Near the end, just before Derek and Danny depart at Danny's high school, Derek says to his brother "I saw a car cruising by the house last night when I pulled out of there with Seth." The car that was shown driving by their house the previous night was in a brief scene right after Derek and Danny took down all of their nazi posters, and before Derek took a shower. He had not just 'pulled out of there with Seth.' The last time he had seen Seth at this point in the movie was at Cameron's party where Seth had almost shot him.
Suggested correction: Just because Derek says to Danny that he saw a car driving by their house when he left with Seth and a black car drove by later in the movie doesn't mean that this is the car Derek was referring to. There are many possibilities to explain what Derek was referring to (perhaps he was paranoid and saw an ordinary car driving by that he thought was scoping their apartment out) but it doesn't mean that the black car is the one he was referring to when he warned Danny.

Character mistake: When Mrs. Doubtfire gets her own TV show at the end, she asks the puppet if he knows anything about England. The reply is, "I only know that it's an island", which is not true. Britain is an island, not England.

Character mistake: The information on Walter's "patient information sheet" lists his address as 5962 Delco St but numerous shots indicate his house number is 238. (01:03:25)

Character mistake: When Ronnie is cutting the article about Roy's encounter out of the newspaper, the title of the article begins with "UFO's...", the apostrophe making it possessive. It correctly should have been "UFOs...", with no apostrophe making it plural as intended.
Suggested correction: You are incorrect. The article is actually correct. It is used as a contraction, not a possessive. http://www.thepunctuationguide.com/apostrophe.html.
It's not a contraction. A plural acronym is simply "s" added to the acronym. An apostrophe never indicates plurality.
Suggested correction: There is no standard on how to pluralize initialisms or acronyms and either way is acceptable, depending on a person's preference. An apostrophe does not automatically make something possessive, such as using apostrophes in contractions to replace missing letters.
Nope. In contractions joining two words, apostrophes only replace vowels (typically the letter "o," such as in "hasn't" or "wouldn't" or "isn't," and most obviously with "it's" replacing the letter "i" in "it is"). In this case, the acronym "UFOs" stands for "Unidentified Flying Objects," and there is no vowel to replace between the "t" and the "s" (in fact, an apostrophe wouldn't replace any letter at all). So, the contraction argument is invalid. Using an apostrophe for "UFO's" makes the acronym singular possessive (such as in "The UFO's movements were erratic").
It seems you missed the point of my comment. What you're stating is an opinion on how to pluralize initialisms and acronyms. While many lean towards just adding an "s", many real life publications back in the 70's did in fact use and "apostrophe s" for initialisms and acronyms. (Notice how 70's isn't possessive or a contraction. But many prefer using "70s.").
"Many publications" were wrong (especially in the late 1970s) and followed poor literary and journalistic standards. No, it's not a "matter of opinion"; throwing in apostrophes where they are not appropriate is a matter of poor education in the English language.
The question is not whether using the apostrophe is "correct" or "appropriate." It's whether it was used by publications in the '70s. It was, therefore it is not a mistake.
You should be more educated when stating opinions then, because it wasn't about being wrong. It was about no set standard. For example "The Chicago Manual of Style" would recommend UFOs while "The New York Times Manual of Style and Usage" would recommend UFO's. Of course, both would recommend using the apostrophe when making single letters plural "A's" or p's and q's."
The New York Times manual of style is predictably bogus. I'm a professor of Journalism (Southwest Texas State University 1979 to 1987). I know what is proper.

Character mistake: When they deliver Xmas presents to Denmark it's already too late - Denmark has the presents on the 24th, early in the evening.

Character mistake: When Cary Grant enters Deborah Kerr's apartment he greets her by saying, "Hello Debbie." Kerr is Terry.
Suggested correction: He says "Hi, Terry", calling her by the right name.

Character mistake: The bank robbers send out a hostage and put a drawer around his neck with a note. The drawer is bugged and the bank robbers can monitor the police. The police just leave the drawer lying around on the table for half of the movie inside their mobile headquarters. This drawer should be in a forensic laboratory being checked for fingerprints and similar.
