Character mistake: When Katie's husband arrives in town and confronts her on the night of July 4th, he says "I miss you Katie." He does not know her name to be Katie as that is the name she created when she came to town. He is married to Erin.
Suggested correction: He says "I miss you, baby" and then "I miss you so much, baby."
Character mistake: When Harley asks Tony what the light is coming from his chest, Tony responds "an electromagnet." Harley replies "What does it power?" An electromagnet is not a source of power. The arc reactor is the power source which powers both the electromagnet (to keep Tony safe from the shrapnel near his heart) and the Iron Man suit. (00:43:25)
Character mistake: Tej mentions that the BMWs they used were factory-line, ie. unmodified. Hobbs then says that they were twin-turbo V8s "spitting out 560 ponies". The BMW M5s they have are E60 models (2005-2010) powered by a naturally aspirated 5.0 liter V10, producing 507 horsepower. (00:38:30)
Character mistake: Towards the start, when Emily mentions that the presidential limo is based on a Cadillac CTS, she is wrong. The Cadillac DTS is the basis for the car, even though it does not carry a model designation anymore. (00:14:00)
Character mistake: When the main characters are watching the news on TV, the headline reads "Terrorist seize Whitehouse". It should be "Terrorists".
Character mistake: Stallone says he knows they are in the Northern hemisphere because of the way the water goes down the toilet. The Coriolis effect has no impact on water in the toilet.
Character mistake: In the scene where Billy is called to the crime scene of Andrews' murder, Andrews' body is shown with a wound on his chest. Later in the movie though, Billy is questioning Todd Lancaster. Todd Lancaster says that he saw Andrews get shot in the head. (00:52:00 - 01:25:00)
Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he says it is "a backwater system with 2 suns and 1 habitable planet."
Character mistake: On the tour boat in London, the voice on the loudspeaker says 'if you look to your right, you will see the Tower of London'. Except it's on the left, given the direction the boat is travelling. (00:53:00)
Character mistake: When Parker awakes in the hospital bed, you can hear the female news anchor say that the thieves got away in a "silver [Chevrolet] Suburban" when actually the Suburban was gold. (00:21:00)
Character mistake: Lewis Dinkum tells Deputy Mike Figuerola it's only a .50 cal round that hit him in the shoulder. The rifle he was shot with was a Blaser R93 LRS2 which fires a 338 Lapua round. A .50 pretty much would have torn him in half. (01:33:20)
Character mistake: The caption under Shrike's picture in the newspaper that Alma is reading, referring to the circumstances of Shrike's accidental death in a locked safe trick, reads 'Police say famed magician Lionel Shrike vigorously attempting to free himself to no avail.' It should be 'attempted', given he tried and failed, then died, so is unlikely to give it a second go.
Character mistake: The Sheriff calls for Drayton Sawyer to bring out his son Jed (Leather Face) in the movie's opening scene. But it's long been established that they're brothers.
Suggested correction: This is meant to be a direct sequel to the original film, and ignores the other sequels. And if memory serves correctly, the first movie never made any mention of them being brothers. (I just checked and the Texas Chainsaw fandom Wiki backs this up - the original film makes no reference to them being brothers.) So therefore, it is not a mistake if this movie re-writes him as being Leatherface's father.
Character mistake: When Joe and Marie are going over files in the old school, Joe finds a staff letter announcing the enrollment of Amanda Pryce. The top of the letter is dated 1984. However, Joe then proceeds to ask Marie to search for Amanda's file, and tells her to search for the year 1986.
Suggested correction: It's possible the incident happened up to 2 years after her enrollment (starting as a freshmen and the incident being when she was a sophomore or junior).
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: When Joan is searching the web looking for information on what monkeys eat, there is a section on the screen that reads "The diet of monkeys varies form fruits, leaves." Obviously the correct word for this sentence should be "from" not "form." (00:36:21)
Character mistake: In the scene where Beatrice looks at the newspaper clipping about her accident. The word "sentence" is misspelled "sentance" (00:24:35)
