Other mistake: The second time Virginia goes down the slide in the 9th Kingdom, you can see that it is a stunt double hurrying to get off at the end.
Other mistake: While Casey was holding the pin she would bump into things and fall in her house. OK that makes sense. However, when she reached the city, how was she walking down steps that are not really there? She should be floating in the air or something.
Other mistake: At the end after the barn fire, Marcia is at a tavern, ordering a rare steak. While it is believable that she escaped the barn fire, it is unbelievable that she is in the tavern wearing the same dress and necklace she wore prior to her transformation in the barn. All of her attire would have been rended in the transformation and lost in the fire. Unless her wardrobe consists of duplicates of the same clothing.
Other mistake: When Frank and Maney are driving through the West Dallas neighborhood and Frank asks to see the file, they pass a green car at the intersection. He then turns onto Bernal St and passes the same green car at the intersection. The houses are also the same.
Other mistake: Why hasn't there been a mention of Freddy having a child in previous films? Couldn't be because they covered it up, as soon as Freddy was discovered to be the Springwood slasher the media would have been all over him and his family.
Suggested correction: Throughout the entire series, it's shown that there's sort a miniature conspiracy going on where the people of Springwood have been trying to make everyone forget about Kruger, including actively suppressing evidence. It's possible that when he was initially caught, the media was aware of his daughter, but not only would it not have been that big a deal (they were focused on him- not his family) in the decades that have passed since his original "death", the information was likely covered up or ignored in favor of trying to make everyone forget about it. (Hence, even Maggie doesn't know Freddy is her father.) Furthermore, the fact he has a daughter has basically no impact whatsoever on the story thus far, so it makes sense it hasn't been brought up before.
It has never been shown in any nightmare film that there is a cover up conspiracy until Freddy vs Jason (which takes place 5 years after this film), and that cover up begins after the events in this film, evidenced by many characters saying it's been quiet for 5 years.
Other mistake: This occurs during the scene where the group has just rescued the colonel. Before Mrs. Paley makes her appearance, the others notice the panel opening, and make movements, but they don't make sense. We'll call the side where the colonel was the north. Sasha is in the southwest corner, and Max is near her. Simon and Jerry are both at the north wall. When the sound of the door opening is heard, Max looks to the west. Simon is kind of in a strange position, but looks correctly to the north, where Mrs. Paley comes from. Simon and Jerry both knew where to look before the door opened, so it's reasonable to assume that it's easy to tell which door is opening, so Max shouldn't have looked at any other door.
Other mistake: The movie is said to be set one year after receiving Annabelle, but the music box from The Conjuring is on the shelf. Judy in The Conjuring is an 8, possibly 9 year old whereas in this film she celebrates her 10th birthday. If Annabelle Comes Home" is only 1 year after obtaining the doll (2 years prior to The Conjuring timeline) then Judy would not be turning 10 years old; she essentially lost a few years of life rather than vice versa.
Other mistake: When Raymond shoots Senator Jordan, his first shot penetrates the carton of milk that Jordan is holding in his left hand. From Raymond's perspective, that carton of milk is positioned over Jordan's upper left arm; so, the first shot should have merely wounded Jordan in the left bicep, hardly a mortal wound. But Jordan's eyes roll up and he collapses as if shot in the heart.
Other mistake: Guy goes to the closet and gets Hutch's coat as he's about to leave after having coffee with Rosemary. If you look at her she looks ghostly as they applied more makeup to her face between shots. Unfortunately they missed some spots around her eyes and on her forehead. (01:06:50)
Other mistake: While in the pool room, Zoey falls off the wall onto a portion of floor that hasn't collapsed yet and loses consciousness. This area is next to the section of floor that collapsed first. Jason jumps down to help Zoey. As he is helping her up, and onto the wall, that section of floor collapses, forcing him to grab the wall to avoid falling 20-ish stories with the floor. As he looks down drop, the section of floor that fell first is amazingly back intact. (00:59:20)
Other mistake: The Volvo the woman is driving has a front Oregon license plate numbered 643 ODS, but her rear license plate is 902 CSM. (00:02:55 - 00:03:45)
Other mistake: During the revelation of the second death, when the killer opens the toxicology report they just retrieved, the date is revealed; it says it was issued on 09/27/2018. But the events of the movie happen in November (it's Sunday 18th Nov when Marta wakes up with all the reporters at her door). It should also be noted that when a close-up of the report was shown earlier (when Ransom was looking at the anonymous letter brought by Marta) that copy had a big stamp in a corner saying 11-17-18, that in this copy is totally absent. (01:56:55)
Other mistake: When "Dutch" uses the call return feature after George Beaufort left the harassing message on his answering machine, he dials #69 on his phone. The actual number for call return is *69. (01:11:15)
Other mistake: When Eddie Valiant gets thrown out of the Ink and Paint Club, he is already starting to go through the air as the gorilla moves his hands to throw him. (00:21:20)
Other mistake: When Harry is being spun round on the ceiling fan you can see that they aren't moving fast enough to hold his body in a stretched out position,especially considering his bulk.
Other mistake: When Ace supposedly wipes the loogies from his eyes you can see his palms are under his eyesockets.
Other mistake: Right after Heather Duke and Heather McNamara drop in on Veronica and Betty Finn playing croquet, Veronica talks to her parents about the suicides. She still has a croquet mallet in her hand, so little time can have passed. Heather Duke rushes in with a shopping bag, and tells Veronica that while at the mall they heard about Martha Dumptruck's suicide attempt. But Heather Duke had just left Veronica's house - there wasn't enough time for these events to happen.
Other mistake: When Anton is swinging below the bridge to rescue Tony from his hanging, he bumps into him. At that moment, Heath Ledger opens his eyes, breaking character for a split second.
Other mistake: When he is talking to his sister in-law during work on the phone, the red wire, which was connecting them so they could talk, dropped or fell out of place. Even though this happened, the conversation still continued.
Other mistake: When the Jeep crashes and John gets out, he sits on the ground behind the vehicle and picks up a shard of glass that's supposed to be from the vehicle accident. Given that all the glass on the jeep shows to be intact, the glass couldn't have come from the Jeep as insinuated by the audio and placement of the shard.
Suggested correction: The windshield broke when the Jeep crashed into the tree and the driver was thrown through it. So the glass of the Jeep is not all intact. That being said, the shard John picked up was a long way away from where the windshield broke.
