Character mistake: The little girl asks Kristen "what's your name?" Kristen replies "Kirsten". (00:05:59)
Suggested correction: I hear her say "Kristen." The transcript and subtitle even say "Kristen."
Character mistake: In his opening prologue, Burt says the Graboids have been contained to the Northern Hemisphere, showing a map highlighting the Graboid attacks of the first film in Nevada and the second film in Mexico. However, it overlooks the Graboid/Shrieker attack in Argentina, in the Southern hemisphere, shown at the beginning of Tremors 3, an incursion Burt personally put down. It's not like it was classified - characters in that movie talk about it being reported by CNN, and characters in the Tremors TV series talk about it as well. And it's not like Tremors 3 is no longer canon, since Burt makes two references to being swallowed by the Graboid in that movie (which also becomes a plot point in Tremors 6).
Character mistake: Alice shoots the henchmen, the black officer is attempting pull a gun from his shoe but in closeup his leg is white, then back. (01:06:25)
Character mistake: When the main character follows the Dutch businessman down the stairs (the same scene the girl with the white jacket and white bag walks downstairs before we see her walking up the stairs) there is a commercial which reads "JETZT AUCH AM DVD" which is wrong and should be "JETZT AUCH AUF DVD." (01:22:45)
Character mistake: In the scene discussing the provenance of the mirror, the girl stated that Sherman marched to the sea in 1865. It was actually 1864.
Character mistake: Over the phone, Julie told her sister Sara, " I got them [parents] a bouquet", pronouncing the "T" in bouquet. Bouquet has French origin so the "T" is silent. Bouquet is properly pronounced like bow-kay (American English) or boo-kay (British English). (00:00:55)
Character mistake: When Erickson is telling Strahm that he no longer has any jurisdiction over the Jigsaw case, he mentions that over a dozen dead bodies were recovered at the meat packing plant, including two cops. There were in fact only 10 dead bodies: Danica Scott, Judge Halden, Timothy Young, Jeff Denlon, Lynn Denlon, Jigsaw, Amanda, Art Blank, Officer Rigg, and Detective Matthews. (00:20:28)
Character mistake: In the highlighted newspaper article entitled 'DeFeo Son Accused' about the killings, the first sentence of the article ends with two periods. Also, in the 3rd sentence, the word 'psychiatric' is spelled "psuchiatric" with a 'u' instead of a 'y'. (00:01:05)
Character mistake: Early in the film we are repeatedly shown the alien character flirting happily with various men, relaxed, confident, even socially forward, in fact often more articulate and socially at ease than the various Glaswegians she encounters. Yet later on, inexplicably, all this social nous mysteriously disappears and she is completely baffled and blindsided by the simplest of social interactions, almost a mute. Since the film has virtually no plot it's hard to see why this jarring turnaround should be so.
Character mistake: Shiwan Khan uses mind control to make Nelson commit suicide. Later, when Lamont is talking to one of his agents, the agent talks about a murder at the museum.
Character mistake: When Trish's car stops running, Tommy states that its the solenoid that is the issue. A starter solenoid is responsible for sending voltage to the starter when the ignition is engaged. 1st problem: The car would not stumble and stall because of a faulty solenoid. 2nd problem: The starter was already engaging while Trish was hitting the key. So bridging the solenoid was pointless. The only reason to bridge a solenoid is to create a connection from 12 volt to the starter when the internal system is compromised due to wear. But that wasn't the case because when she was trying to start it, the starter was turning the engine. Plus the solenoid has nothing to due with the way an engine will perform (running, misfiring, not running).
Character mistake: When Duddit's mom is packing his lunchbox, she refers to him as "Henry". (01:45:54)
Character mistake: Remy mentions that the insects are part ant, cockroach and termite. She dismisses the mantis side, which allows it to mimic.
Character mistake: Laura is on the floor, screaming and exhibiting bizarre behaviour, so Dr. Rose Cotter goes to the wall phone to call for help. Instead of maintaining observation and continuing an evaluation of Laura, the psychiatrist faces the wall while making the call and even stares at the wall for a couple of seconds after hanging up. A patient's body language can/do help make a diagnosis, so the psychiatrist should keep her eyes on Laura. (00:11:20)
Character mistake: It doesn't occur to our heroes (admittedly kids) that you don't need to understand German at all in order to read it out loud. It's arguably easier to read than English! The only inscrutable letter would be "ẞ" but Scary German Guy's right there for help. (True, this is essentially what they end up doing in the end, but they still come about it through a "you don't need to be of age to be a virgin" realization rather than the even simpler "you don't need to know German.").
Character mistake: There's a note from "mother" on the wheel at the diner. Right beside it is an order with the wrong total. 2 hamburgers for $1.95 each. 2 fries for 90 cents and 2 drinks for 90 cents for a total of $5.70. The waitress put $3.70 for the total.
Character mistake: When Burt, Ernie and Spider go into the hall after questioning the zombie Burt says his own name instead of Ernie or Spider.
Character mistake: The news article on the murdered gentleman David Carradine discusses has the word existence spelled wrongly. It says existance. (00:37:57)
Character mistake: Reina asked Cory if they could "do that thing" because it was helpful for her medical school training. Reina then put a raw slab of steak/meat across his forehead and made slits in the meat as well as jabbed at it. A medical student studying to become a brain surgeon should know about and practice the safe handling of raw meat. (00:23:10)
Character mistake: When searching the database for the missing girl, they find her and it says missing since 7 January 2021. When Caleb read it, he says "missing since February..."
