Factual error: When Danny and Sarah cut in front of the truck to take another route, there were at least 14-17 bullet holes through the rear window alone. Glass on that year of Mustang was not laminated and the bullets would have struck them. (01:27:35)
Factual error: One of the warriors tells a trainee they move like a sloth, more than once. Sloths are only found in the "new world", not native to Africa.
Factual error: In one scene, Winifred asks Gilbert who Trask is and Gilbert replies that Trask is the "mayor", to which Winifred just acknowledges. However, the office of mayor was not created in Massachusetts until 1823, which is 130 years after they were hanged, so given the witch's lack of knowledge of the modern day, she would have likely not known what Gilbert meant.
Factual error: The owl that JP was looking at made a "who who" sound. The owl may appear to be a Snowy Owl (one many people are familiar with), but it is a Barn Owl. Barn owls are not "true" owls and it is the true owls who "give a hoot." Barn owls don't hoot; they make a screeching or squealing sound which can be piercing (and eerie to some people). (00:32:50)
Factual error: When the Allosaurus bent over to pick up her egg (which was almost touching a newly-thrown hand grenade), the hand grenade exploded only toward the right of the screen, engulfing the dinosaur. A hand grenade would/should explode in all directions. (01:19:30)
Factual error: Considering everything that happens after Lester comes down the stairs at Samantha's house around 10:05 PM, it is impossible for it to only be 10:15 when she sits down to eat pizza. Their scuffle and Samantha somehow getting Lester zip-tied in a chair alone would take much longer than 10 minutes. (00:15:42 - 00:38:28)
Factual error: Though the Elvis Christmas Special was shot in June 1968, Bobby Kennedy's assassination happened on June 6th and not while the recording had place -as the movie depicts - between June 27 and June 30.
Factual error: Henry appeared to punch Jason higher on his left side and more toward the back than where the bruise was later shown to be (closer to his waist). More significantly, the bruise quickly changed colors from red/blue-purple to the entire large area being bluish-purple and deep purple. However, bruises typically take at least one or two days to change to deep purple. (00:45:55 - 00:49:19)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Factual error: Sam Cooper's Rx label was for Alprazolam (generic Xanax) 2 mg, qty #150, refill 2x, and "take 1 tablet by mouth as needed." "Must last _" length was not visible and there could have been warning stickers (may cause drowsiness) on the other side. However, Xanax is a fast-acting tranquilizer which should last 6 hours and the dosage should not exceed 10 mg per day. The instructions to "take 1 tablet by mouth as needed" should have had restrictions attached to prevent serious side-effects/death. (00:49:38)
Factual error: The Lenox Hotel and The Copley Plaza Hotel are a block away from each other. Griffin did not need to take the horse and buggy and then a bus to get there. They are way too close for that.
Factual error: The "X"s crossing out days on Don's calendar indicated it was Thursday June 9, 2021 [but June 9th actually fell on a Wednesday]. Allen was watching a TV show that aired 12:30 - 2:30 AM, so Allen was smoking outside in the dark during the early morning hours of Friday June 10th. A Full Moon was shown after Allen was watching TV and before he went outside. Full Moon didn't occur until June 24, 2021 (about two weeks later) during daytime hours (11:39 AM - 2:39 PM, depending on the time zone - 1:39 in OK). (00:19:37 - 00:30:19)
Factual error: Birdie tries to use the tune recognizing app Shazam speaking to the wrong device. When she does that, the TV in the background plays footage from CNN, with the coronavirus epidemic, featuring Dr. Fauci. However, in that particular part of the scene they also show a map of the US that displays the states with no mask mandate. The chart can't be a May 13, 2020 one (supposed date of the scene), since it shows the situation at the end of the year. Several states in white like Washington, Nevada, Oregon adopted it only in the summer. (00:08:20)
Factual error: Doctor Key tells Mary, "If you pose a threat to those around you, we will be forced to keep you here [hospital] longer. That means your son will be placed in foster care." Family members, such as the grandmother and uncle currently taking care of Tony, are preferred before placement in foster care. Foster care is usually considered among the last resorts, not first, and only when there are no suitable family members or significant others to provide temporary care for a minor. [SPOILER: It isn't known that the grandmother and uncle aren't biological relatives.] (00:29:15)
Factual error: When Laura dropped Cody off at school, there was one boy (far left side of screen) wearing shorts. In 1950s (and later) California, boys were required to wear long pants to school (no shorts!) and girls had to wear dresses. (00:15:26)
Factual error: "Mon, April 28, 2019" was displayed on Alex's cell phone, but April 28, 2019 fell on a Sunday. (00:51:00)
Factual error: Pettis' calculation of the amount Connor needed to replace his asset was way off. He stated, "[Cornell] brought me about 250 [$250,000] a year. He had at least 20 more years of service. Subtract five years he might have spent in prison, so you owe me, what? Six point two million." Pettis was presented as intelligent, but a quick mental calculation of even the full 20 years at $250,000 would total only $5 million (not $6.2 - an odd sum). For 15 years, the total would be $3,750,000. (00:28:45)
Factual error: At the end of the film a character is walking through a studio lot in 1952. Through the trees behind him can be seen a section of a poster advertising Jackass Forever (2022).
Factual error: During the storage unit robbery in the beginning of the film, simply knocking the combination dial off the safe would not have caused the bolts to suddenly retract. It would defeat the entire purpose of having a combination lock. Even inexpensive safes have mechanisms to prevent this from happening.
Factual error: Twice during the movie, streetlights are visible: once when lady Russell informs Anne of Wentworth's engagements, and once while Anne is running after Wentworth. (Streetlights, lit by gas, were indeed conceived during the regency period - but they were experimental curiosities, and certainly not yet installed nationwide).
