Factual error: Right at the start of the film, it shows the girls going up for the first day of school which would have been around Fall. It shows tulips blooming in the garden, but tulips only bloom during the spring. (00:00:55)
Continuity mistake: When Roberta comes over to give Mark the doll he left at the shop, we see an animated sequence just before this. The character in the animated sequence gets her top ripped open. In the real life version, the doll has more of its shirt ripped open.
Continuity mistake: While Sam puts Slappy on the junk cart the sun changes between shots.
Audio problem: When Mrs. Hudson finds a package for Sherlock instructing him to open it before the trial, she says "I never even heard anyone knocking" whilst handing it to Watson, but the line appears to have been dubbed over as her lips don't match up with the dialogue.
Continuity mistake: The clock time on the top right of the laptop screen near the start changes from Sun 17:59 to Sun 16:00. (00:08:39)
Factual error: Jonah Hill references "Chucky" from the movie Childs Play. This movie's period is set somewhere in the late 1970's. The movie Childs Play didn't come out until 1988.
Continuity mistake: In the strip club scene, he goes to the bathroom with his shirt unbuttoned. He reaches into his pocket and starts dialing a number. The angle changes and his shirt is completely buttoned as he finishes dialing. (00:25:10 - 00:25:40)
Continuity mistake: Spoiler alert: At the end of the movie "Rose" stabs "Miles." We see her pull out the knife and it looks like a Rambo-type hunting knife. After she stabs him, we see the knife covered in blood but it is a different type of knife. It looks more like a skinning knife or filet knife.
Plot hole: There is no way Anna could know that Hester was going to be at the auction. The circumstances that led to Hester and Tom being captured can't possibly have spread to the Anti-Traction League, they were immediately taken to the slave auction after being captured. Anna also instantly recognizes Hester when she sees her despite the fact that Hester was 8 years old the last time she would have seen her.
Suggested correction: Anna might have very well just been there to do anti-tractionist things, it was an auction made of towns after all a prime target to hit many options at once or hide bombs on for a bigger city to gobble up and go off later. Once she saw Hester her plans simply changed. As for how she recognized her, it is possible Anna had been tracking / keeping an eye on her. It wouldn't be impossible to ask around for a scar faced girl moving from town to town and might have gotten a pic somewhere.
These are all wild guesses that aren't confirmed by the film itself. They do not qualify as corrections.
Continuity mistake: When RBG leaves for court (about 30 minutes from the end the movie) her brooch is on the right lapel of her black suit and when she gets out of the cab, it is on her left.
Continuity mistake: After Dumbledore gives Newt the card for the safe house in Paris, they teleport to a bridge where they continue talking. Dumbledore then tells Newt why he likes him so much, and in the side shots, Newt is shown holding the card up. When it cuts to angles from behind Dumbledore's shoulders, his arm and hand are much lower with the card and his head turned in a different position. (00:20:35)
Character mistake: During an intermission following Dmitri's revenge after the attempted hit on him, the Chief of staff discusses the data with Dr. Updale. There's a pie chart in the screen in the background, and the segments are; 5%, 25%, 16%, 14% and 50%, which add to...110%. It's not a pie chart, it's a pie and a slice. (00:50:15)
Revealing mistake: The paddle steamer on which Wilde crosses the Channel has her name "Waverley" visible on the bow. The Waverley, the world's last seagoing paddle steamer, was launched in 1946, 46 years after Wilde's death. Replacing the name with the name of a real paddle steamer of the era would probably have been a good idea.
Deliberate mistake: An LAPD cop discharges his firearm a full size Glock which has a minimum magazine capacity of 13+1 for the Glock 21. The Glock 21 is approved LAPD issue along with other variants. He fires maybe three shots and the slide locks back signalling that it's dry. A second later the same cop is walking with the same empty Glock aimed towards the suspect which was shot at. It's visible that the slide is being held back by the slide stop since the magazine went dry. (01:29:58)
Other mistake: Daphne's dad drops the Legitimate Tulip badge in front of her so she'll avoid getting hurt, but when we see him do that, he does it before the warning for the ball is heard and seemingly not looking at the danger (especially in the second shot, when he is peeking from the corner). So his action makes no sense. (00:16:55)
Factual error: The movie is set in Van Diemen's Land (now Tasmania) in 1825. Throughout the movie, in scenes where Clare talks to the aboriginal tracker, Billy, subtitles state that they are speaking in Palawa Kani. Palawa kani was developed in the 1990s by the language program of the Tasmanian Aboriginal Centre, more than 165 years after the movie.
Other mistake: At the end of the movie Lorraine has to remind Elise that she helped her once, implying they haven't seen, or spoken since. When Elise first meets Josh in the 1st insidious she tells Josh that her and Lorraine have been friends for a long time, implying they talk or see each other regularly.
Suggested correction: That's debatable as the word "friend" does have to do with semantics. I have friends I have not spoken to in a long time, or speak with rarely, but still consider them friends due to our history. Others would say that's not a friend as that's not what they think of when they hear the word "friend." So it does depend on the individual person. It's also quite possible this is what they told Josh as the cover story for why she was contacted since they initially didn't want him to remember his past.
Factual error: Max could not have been accidentally shot when Annie drops the revolver. She dropped it when she was startled by firing it into the ceiling so the hammer would still be sitting on the spent/empty shell casing. The trigger or hammer must be pulled back in order for the cylinder of a revolver to rotate to the next live chamber.
Factual error: In the bar scene there is a sign for Genesee beer. That brand never went west further than Pennsylvania.
Deliberate mistake: Earl attended the "2005 National Daylily Convention." The wording is not accurate, perhaps for purposes of brevity. There is no "National Daylily Society", but there is an "American Daylily Society." Likewise, there is no "National Daylily Convention", but there is a "National Convention for the Daylily Society." (Incidentally, the dates for 2022 are/were July 6 - 9). (00:03:43)
