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)
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.
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)
Plot hole: Spoiler. Alana discovers the alternate memory pathways in the film while Eve is lying back in the chair with the Mem Scanner on showing it was actually Eve that killed the crew on the pod. But as she's watching it, shots show Eve in the background not wearing the Mem Scanner. So Alana watching the memory feed then would not be possible. It was not recorded and played back until later. (01:19:00)
Continuity mistake: When Priest and Georgina throw the molotov cocktails at Juju from the balcony, watch closely - right as Priest throws the second molotov cocktail and the camera cuts from a bird's eye to a ground-level angle, the position of the two men and the carpet they're standing on changes between cuts.
Character mistake: Immediately after the crash, when Reeves is carrying his youngest child Sophie, the actress opens up her mouth, even though she has already drowned. (00:14:43)
Character mistake: The tour guide inside the "Degenerate art" exhibition ridicules the 'child-like' paintings of the likes of Mondrian and Kandinsky. In particular he stands in front of Kandinsky "Upward." The German name of the work is "Empor", but the tag says "Empore." (00:03:40)
Factual error: When the saturation divers open the outer hatch on Kursk, they drop a glow stick. When they do, it falls to the floor on the submarine, indicating the inner hatch was open. The inner hatch of Kursk was closed, later opened by an ROV.
Revealing mistake: Davey at the beginning of the movie is looking at the newspaper he's delivering to Mr. Wayne Mackey. Just from a glance at the page you can tell that something is off, since the article supposedly about a missing boy appears to be written entirely in first person. Upon closer inspection, turns out that it's filler text from chapter IV of Robert Louis Stevenson' s "Treasure Island". (00:01:30)
Factual error: Second scene, caption says "1977 southern California" but she's driving a white 90's Oldsmobile Cutlass Ciera Fwd station wagon.
Continuity mistake: When Lukas is looking in the bathroom mirror, the upper half of his laceration looks about three times the width of the lower half. When he exits the bathroom, the laceration looks like one line with the same width. (00:15:45)
Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.
Other mistake: The RV's cassette player has some odd features (some of which I've never seen on a cassette player). There's a "push button" for "loudness", not "volume." There is another "push button" labeled "MO ST" - not sure what these mean. The slot for the cassette tape looks wide enough for a VHS tape. (00:11:15)
Suggested correction: There's nothing wrong with the stereo. The cassette slot is the normal size for that configuration on an 80's cassette car stereo (they're in an '87 Suncrest). The loudness button was also a common feature for that era. It boosts low and high frequencies at lower volumes (the stereo still has a volume knob). MO stands for "mono" and ST stands for "stereo."
The slot looked way too wide, even for the 1980s. I would have guessed that the "ST" meant stereo, but wouldn't that be referring to the AM/FM radio, not the cassette player? (Thanks for the "MO" clarification). [Features were still on the odd side.].
Continuity mistake: Mr. Shamsher at the beginning of the movie steps out of the helicopter with one door open, but when he brings across the other leg both of the large doors are suddenly open at the cut. (00:03:00)
Continuity mistake: Ron Perlman and Famke Janssen are having dinner on his supposed birthday. The whole meal has several continuity errors, with her fork being at different heights, sometimes replaced by the wine glass, etc. (00:34:30)
Continuity mistake: Dan set his lighter on top of the pack of cigarettes with their bottoms flush, but a close-up showed the lighter at an angle with one corner protruding past the bottom of the pack of cigarettes. (00:04:52 - 00:05:28)
Factual error: Spoiler! The cultists burned Mandy alive by wrapping a sleeping bag around her, putting gas on her and hanging her from a metal swing set and setting her on fire. After Red frees himself later and craws up to her remains, it's shown that she is barely a pile of ash with her skull still somewhat in shape when he picks it up. It then crumbles into just ash showing she had been fully burnt to the very center. This would not have been the case with how they burned her. Their was nowhere near enough heat or kindling to keep her body burning long enough to turn completely to ash with no remains like that. She would have died, yes, but would have mostly stayed intact as a single body burnt very bad. Bones, features, charred organs would still have been left behind. (01:04:00)
Continuity mistake: In Alice's apartment the clock on the wall has the time as 8:40 when she is standing and kissing David. They have sex and Veronica comes over. Alice and Veronica talk and the clock still shows 8:40. (01:20:00)
Continuity mistake: When Sophia is talking with Rachel after she brings the proteins, Sophia's fingers on her cheek swap between extended or bent between shots.
