Factual error: It is not possible to have a conjoined twin of the opposite sex. They are similar to identical twins, which are always of the same sex, in that they are formed from a single zygote. In the case of conjoined twins, the zygote fails to divide normally.
Suggested correction: There are always exceptions to the rules and, although VERY rare, it IS possible for conjoined twins to be - rather, end up being - different sexes. There are about 10 documented cases. In one case, is my understanding the conjoined twins started out as males but a genetic mutation (or something) occurred and one male lost his Y chromosome, thereby developing into a female with no ovaries. (The now-female twin would have so-called Turner Syndrome.) I don't have any sources to quote off-hand.
The male would have lost his Y chromosome after the zygote "split", but he was a monozygotic male.
Factual error: Neighbor states: '72 Challenger, 4.9-liter, V8. The '72 Challenger came with a 3.7-liter slant-6, 5.2 and 5.6-liter V8. (00:11:30)
Suggested correction: Sounds like the neighbor is mistaken, which would just be a character mistake. Remember, the car wasn't his. He had just inherited it, recently as Hutch points out. He admittedly didn't even know the correct 0 to 60 time.
Factual error: When Cruella first drives her iconic car, being in Britain the driver's seat should be on the right side, not the left.
Suggested correction: Cars can be imported from overseas. It's very possible the car was imported from America.
Factual error: In the beginning, it's 1989. The crew chief, Michael Rooker, is wearing Mechanix gloves... which didn't come out until the 1991 Daytona 500.
Factual error: Dwayne Johnson is pursuing a thief. He gets into a Porsche Taycan and pushed the start button, and he can drive off. But you have to have the key fob in your pocket or bag. Porsche explains: "As long as your key is close when you grab the door handle, the system automatically checks the encrypted access code on the key. Once your code is validated, the door will unlock, and you'll be granted access to your vehicle." Dwayne had no fob, as the car was just parked.
Suggested correction: I assumed the car belonged to the guy who was stood just in front of it, so the fob would have been in his pocket, close enough to start it.
Maybe the owner was so stupid to leave the keys in the car. "Who can steal it, here in front of me?"
Maybe start it, but since he drove away, the fob would no longer be in his possession and although the car would continue running one time, it could not be restarted.
Factual error: Lady Gaga is painting her toenails listening to some music on her portable cassette player. It's 1978, and walkman-type players were introduced the year after. (00:11:00)
Factual error: There is a "Covered California" sign in a window. The referenced health insurance exchange did not exist during the 1990 time setting of the movie. (00:20:58)
Factual error: The Sheriff's car had "POLICE" written across the rear end, but with the exception of Allegheny County, deputies in Pennsylvania do not have police powers. They are County employees who carry out court orders (e.g, serving warrants and subpoenas) and work in court houses keeping order. They also transport prisoners and issue gun permits. It would be atypical for a Deputy sheriff to do routine patrol like Deputy Myers was doing. The sheriff's car should have had "municipal" or government plates. (01:16:18)
Factual error: When the hackers take out Zagreb, Croatia, one shot shows the effect on a train in a subway station. Zagreb has no subway.
Factual error: Georgia license plates have the county (where issued) at the bottom of the plate, but the plate on Jimmy's truck does not show any county. (00:08:32)
Factual error: After Ressler tells McChesney he wouldn't be surprised if one day she's tracking down sequence killers, McChesney replies, "Not sequence killers. Serial killers. That's what they should be called." But it was Ressler who claimed he coined and is often credited with coining the term "serial killers" (at least in the U.S). ** After showing pictures of some of Bundy's victims, Ressler is shown and it is pointed out, "He [Ressler] is credited with coining the term 'serial killer'." (1:31:30). (00:26:40)
Factual error: Unless left in the vehicle (not the case here), towed impounded vehicles do not have keys. Moreover, lacking keys, a valid registration, possibly proof of insurance, and new plates, vehicles bought at a NYPD auction are to be TOWED away. A newly-purchased auctioned vehicle, such as the Navigator in the movie, is "ticket-" or "citation-ready", not ready to be driven on the streets.
Factual error: At the beginning of Quintet, a modern Manhattan skyline is visible in the distance not a late 1950s skyline. Also, the view is consistent with the Paterson, NJ filming location, not the Upper West Side.
Factual error: When pit bull Shadow was chasing Phoenix, the distances between them varied - even appearing to increase - but the pit bull should have been able to quickly close the gap and catch Phoenix. In general, an adult person (about 7 mph) cannot outrun a pit bull (25-30 mph). Also, unless Shadow was trained to stop pursuing Phoenix if she got over the fence, pit bulls are actually quite good at climbing fences. (00:02:38)
Factual error: One of the sisters threw a bucket of water over the dock to wash away the blood. Seconds later, the dock was dry. Even with the sun shining, wood does not dry that fast. (00:10:03)
