Character mistake: During the fight in the double deuce where Wesley brings Jimmy in to take all the bouncers on, Jimmy takes on Wade, and Dalton comes to his rescue. Afterwards Wade says to Dalton 'same town new story', when in fact the line should have been, 'new town same story'.
Suggested correction: Wade said it that way on purpose. He was alluding to the idea that there is something different about this town's situation, compared with all the other towns where it was the same old situation.

Character mistake: When Katniss is trying to destroy the supply pile, we see a close up of her drawing back on the her bow. We see she has the arrow to the left of the grip, meaning the fletchings (feathers at the end by the string) have to be facing to the left. Otherwise the fletchings will hit the grip, rip off, and make the arrow unstable in flight and go completely off course. However, the fletchings are are facing to the right and so will hit the grip. Any archer or anyone who is skilled with a bow would know this. (01:32:45)

Character mistake: When Jackie the babysitter is stuck in the closet, she explains to George and Kathy that the door was locked. George says Amy there's no lock on this door. Her real name is Amy and her film name is Jackie.

Character mistake: When Anastasia has to make out the 5 million dollar check to "cash" to get the money to release Mia, she signs the check with her old last name, "Anastasia Steele" instead of "Anastasia Grey", which is written on the top left corner of the check.
Suggested correction: A key point in the movie is how Christian is upset that she didn't take his name in her work life, so it wouldn't be unreasonable that she signed the check using her maiden name (it also could have been just as easily a force of habit thing, it does take time to get used to using the correct name!).

Character mistake: When Eastwood is trying to mount the horse for the first time he is pulling on the inside rein, which makes the horse turn away from him. Even a child of that time would know to pull on the outside rein to make the horse turn into you.

Character mistake: When Paul is looking through Annie's album, there is an article on her as a nurse. The headline has her name as Annie M. Wilkes. But, in the accompanying photo her name is listed as Annie C. Wilkes.

Character mistake: When the adults are inventorying the weapons in the armory, one of them walks over to a case of pistols and says, "Pistol, 45 millimeter, M 1911A." The M1911A is a .45 caliber pistol and is listed as such right on the crate. There's no way the actor could have read "45 millimeter" anywhere on the crate.

Character mistake: During the "heart attack prank" just before the paramedics get to Frank, Eastwood mistakenly opens his eye before the paramedics wake him.
Suggested correction: It's quite possible that Frank was awakened by the commotion of the EMTs rushing in.

Character mistake: At the football players funeral, the guy on the left is still breathing, despite being dead.

Character mistake: The so-called cobalt chlorium (.) G, which is supposed to be used in the Russian doomsday device, has, according to the Russian ambassador (and Dr. Strangelove), a half-life period of 93 years. He then states that it would contaminate Earth for 93 years. However, per definition half of the radioactivity would still be left after this period. (00:47:30)

Character mistake: Mattie attended a travelling Old West show in Memphis in which Rooster Cogburn was a performer. The flyer for the show shows the date of the show as July 18, 1903. The day of the show Mattie was told that Rooster died three days earlier (July 15, 1903). But Rooster's tombstone lists the date of his death as August 12, 1903. (01:41:55 - 01:43:35)

Character mistake: When Jenny is dead, Ellis attempts CPR on her, but his hands on her chest are far too high; they should be just up from the base of her sternum, his are nearly under her chin.

Character mistake: When preparing for the parade, Shellhammer tells Dorey that her Santa is wearing a topcoat and a fedora. Kringle is actually wearing a Homburg, noticeable by the lack of a pinch at the front.

Character mistake: When Woody Harrelson picks up the movie magazine and opens to a page, he says "I love Clara Bow." The picture he is looking at is of Jean Harlow. (01:00:54)

Character mistake: A newspaper is shown saying "Girls Body Found" as plural when it should be "Girl's Body Found" as a possessive.

Character mistake: When Troy is getting the bomb ready, the screen shows it will blow in 216 hours, which is 9 days. Yet the agent tells Archer it will blow in 6 days.

Character mistake: Throughout the movie the character Andrea's name is consistently mispronounced. When her husband Chris shows up at her office to apologize for looking at her bank statements and offer to take her to lunch, he approaches the receptionist saying he's looking for his wife whine he calls Andrea (pronounced like Ann-drea) but then in the same scene he calls her Andrea (pronounced Ahn-dre-uh) I understand maybe another character mispronouncing her name but not her own husband.

Character mistake: When Rommel leaves his French headquarters for Germany on June 5th for his wife's birthday on the next day, he erroneously states that date as 6th of July (pronounced yoo-lee), not June (pronounced yoo-nee). (00:29:30)

Character mistake: Blore accuses Lombard saying "What about those 21 poor natives in South Africa?" The record played during the first evening mentioned indeed 21 men, but that were natives of a tribe in East Africa. (00:14:20 - 01:10:10)

Character mistake: When Werner asks Hendley why, as an American, he fights alongside Britain, he mentions that the British burned down the U.S. capital in 1812. While it happened during the War of 1812, the burning of Washington actually occurred in 1814. (00:11:10)
Suggested correction: The question was intended to demonstrate how far out-of-touch Werner was with United States history.
You misunderstand. Werner's question in and of itself is not the mistake; it's merely a point of contextual reference. The mistake is him giving the incorrect date of a historical event he claims to have read about; it's hard to believe that every book that he might have read on the topic are all wrong, so he must be remembering, and thus repeating it, incorrectly.
