Factual error: When Famke Janssen pulls the knitting needle out of her cast to stab her attacker, it makes a sound like a sword being pulled out of a sheath. It should not have made that noise, since it was between a plaster cast and her skin. (01:19:01)
Factual error: When the knockaround guys are riding in their rented vehicle from Wibaux, Montana, their license plate starts with a J and is followed by several numbers. In Montana, license plates start with one or two numbers, followed by a P or a T, then four more numbers and one more letter at the end.
Factual error: When Sarah leaves the hospital, she pulls out her drip, but does not bleed from the wound.
Factual error: When Mike first starts listening to the session tapes, the camera does a slow pan down the label on the box. Quite clearly, we can see that the patient's diagnosis is listed as "D.I.D.", along with a few names. Since the hospital closed in the mid 80's, it is not possible for her to have that diagnosis. Before the early 1990's, D.I.D. (Dissociative Identity Disorder) was known as M.P.D. (Multiple Personality Disorder). In later scenes it is correctly listed in the woman's files as Multiple Personality.
Factual error: The movie "Cat's Meow," about a real incident that occurred on William R. Hearst's yacht, includes a scene where a female guest, awakened by a gunshot, is wearing hair clips. Those objects were not available in the 1920s, and even if they were, they are totally ineffectual on her combed-flat hair style.
Factual error: The movie takes place in Connecticut from 1961-1986. All the cars in the movie have license plates on their front bumpers, but Connecticut didn't require front plates until just a few years ago (late 90s-early 00s).
Factual error: The horn on the LT's Range Rover is at the end of the signal lever not in the middle of the steering wheel as shown.
Factual error: Vince has a chat with his daughter in 1974. The movie poster on her door is for the Yellow Submarine. Yellow Submarine came out in 1968, but the poster shown is from the 1999 re-release.
Factual error: At the end of the movie, the son arrives from Dartmouth. But he does so in Grand Central Station. To come from New Hampshire he would have to arrive at Penn Station. (01:53:40)
Factual error: The corporal mess steward addresses the sergeants as 'sir'. British sergeants are never addressed as 'sir'.
Factual error: In the scene where the resistance blow up a German train, the locomotive is a British one. The number is shown as 92240. This engine is owned by the Bluebell railway, who are named in the credits. It wasn't even built until around 1955. It seems to be the same engine pulling the train to the concentration camp later in the film. Remarkably fast repairers, those Nazis.
Factual error: When Hal meets Rosie's mom, she is a large woman but her hands are skinny. If someone is the size as her character, they would have large hands as well.
Suggested correction: Actually when Hal first meets Rosemary's Mom, she is shown skinny as does Rosemary through the way that Hal sees them. It's not until later in the movie after Hal's hypnosis is gone do we (and Hal) see the "real" fat mom and rosemary and their hands do look a bit larger by then.
It is obvious that Rosemary and her mother are wearing 'fat' suits as neither women are large in real life. The suggested correction in invalid as throughout the movie, the only time Rosemary's hands appear large are in spots. (eating the taffy apple when she met Jill, and rubbing Hal's cheek when he had the goop on his eyes. Yet you never see the full body with a face in those shots.) Therefore, as I stated in the factual error, when Hal meets Rosie's mom at the end (at the party), she is wearing a fat suit, but her hands and Rosie's are skinny. It's a valid movie error.
Factual error: In the end where Larry and Brian are sitting in the garage, one of them is watching a hit counter for their website, and the other is watching the news stream on the computers. When the reporter is walking up the driveway, she mentions that the site has had 18 million hits.. how did she know this? The SkullBocks server was inside the garage, so the reporters couldn't have checked before hand. And even if there was a counter on the website, they were getting 400 hits per second (1,000,000 hits takes 41 minutes). Assuming they looked at a counter, before the reporters left, it would have been a lot less then 18 million. In addition to this, when they open the garage door up, another reporter asks "How many hits have you guys registered?"
Factual error: At the end of the film when the news reporter says 'Isn't that the guy who had the skunk on the freeway?' then you hear a voice calling him back to look at the camera. This is wrong, as if they wanted his attention on the camera, then they would call him through his headset.
Factual error: The newspaper pictures are too glossy to be newsprint.
Factual error: In the movie, the over is shown to be of six balls. In 1896 the British played cricket with a five ball over.
Factual error: When Donnie returns to his house to find a jet engine has landed on it, we see them lift the jet engine up with the crane. Yet his family, complete with 5 year old girl, are standing right in front of the crane. Plus workmen are milling around underneath and about 4 FAA officials come from inside the house. They are lifting a 2000lb jet engine, and all these people are allowed to wander around while it's 20ft above them?
Factual error: In a short scene, Sissy Spacek is seen walking down the sidewalk with a 16 ounce cardboard cup of coffee with a cardboard cup holder. The film is set in the mid 1980s, well before regular people walked around with coffee shop coffee in a cardboard cup.
Factual error: In the closing credits, Eva Mendes' name is spelled as both Eva Mendes and Eva Mendez.
Factual error: When the protagonists arrive to Patmos, latitude and longitude are switched the other way around at 26°489 and 37°411. Moreover, that's not Patmos, but Anydro Patmou, an uninhabited islet unlike what is shown here.
