Factual error: Lynyrd Skynyrd's plane crashed in the early evening in October 1977. Injured crash survivor Artimus Pyle, tended to the severely injured people and later was able to walk through the swamp and the woods in the dark to get help, but in the movie when the plane crashes and Pyle's search for help it's a bright sunny day.
Continuity mistake: When the girls are standing on the beach with the flares to guide in the German aircraft they are in two rows just a few metres apart. The view from the aircraft shows them much further apart, wide enough for the aircraft to land between them.
Other mistake: The Volvo the woman is driving has a front Oregon license plate numbered 643 ODS, but her rear license plate is 902 CSM. (00:02:55 - 00:03:45)
Visible crew/equipment: The diner flashback has possibly one of the worst handling of extras ever. The lady behind Crystal Fox keeps glancing at the camera and playing with her food in very unnatural fashion, but it's the guy with glasses behind Mehcad Brooks that truly shines; throughout the scene he drinks from an empty glass and, even more obvious, eats invisible food from his fork, usually throwing a glance right at the camera every time he does so, looking like he's about to crack into a laugh at the absurdity of it. It's such a bad performance that one really wonders if he was trolling Tyler Perry or something. (00:32:25)
Other mistake: In the credits of the movie, the creator of the original comic's name is misspelled as "Bob Macleod" when it should read "Bob McLeod."
Other mistake: The rectangular area of skin cut from the dead deer's rear side was not wide enough (or at the correct angle) to encompass the killer's entire bloody hand print; it would have missed the "pinky" finger (and possibly the tips of the second, third, and fourth fingers). Because the fingers were spread out, a shape more like an inverted isosceles trapezoid (or a much wider rectangle) would have been necessary. (00:42:52 - 00:44:09)
Factual error: When John Thornton is in the bar, Hal comes up and punches him in the face. They fight and argue, and Thornton proceeds to say that Hal "sucker punched" him. However, the term sucker punch was first known to be used in 1926 while Call of the Wild was published in 1903. The story itself took place in the 1890s.
Factual error: The river that Tyler Rake falls into near the end of the film, the Buriganga, is one of the most polluted rivers not only in Bangladesh, but in the world. There is no way the water is as clear as it appears when Tyler falls into it. It was done for effect, but nonetheless it's not accurate.
Suggested correction: The river is certainly polluted. But unless you have evidence of the view from under the surface, looking up, with the sun shining down, it's impossible to say that the water in that situation wouldn't look as clear as shown.
Other mistake: Dolittle starts with a voiceover narrative explaining how Dr Dolittle was deeply in love with a beautiful woman called Lily. On an ocean voyage Lily disappeared and was presumed dead. Dr Dolittle never got over Lily's loss. As a child I recall reading all of Hugh Lofting's Dr Dolittle books (now generally castigated for political incorrectness) and I am 100% certain that Dr Dolittle was unmarried, and never once had the slightest romantic inclinations towards any woman.
Character mistake: Bart is sitting on a bench outside the hotel. After Detective Espada talks to the Mercer hotel manager/owner, he goes to talk to Bart. Bart has blood on both hands and lower left sleeve. Detective Espada is supposed to be investigating a fresh murder case that puts Bart at the scene, but he does not confiscate Bart's bloody clothes, conduct a gun powder test on Bart's hands to check for residue, or take him to the police station for formal questioning. Espada did not follow police protocol. (00:17:36)
Factual error: Apex, played by Robert Maillet (a retired professional wrestler 6'11" and 350 pounds), forcefully slams Becky (played by 5' tall fifteen-year-old Lulu Wilson who probably weighs under 100 pounds) horizontally with her back hitting the ground from waist-high yet Becky is able to get up with no incapacitating injury that would be expected. Becky also manages to brutally kill him (as well as the three other neo-Nazis).
Continuity mistake: David Spade just sat down with the prankster blind date. When she (kinda accurately) says "By the way, the age thing..." his hand in a blink goes from the table to the back of the couch. (00:02:20)
Other mistake: The way Katelyn exploded was described by Mara as being like a balloon popping. Every time a student exploded, blobs of blood (and tiny pieces of the body) splattered everywhere, making a huge bloody mess. When more than one student exploded going down the stairs, blood looked like it was being poured from a bucket. Sometimes, parts of clothing could be saturated in blood (such as a sleeve), but there was always more blood splattered nearby. When Katelyn was at the doctor's office (to get a piece of someone's bone removed from her forehead), "blood" goes smoothly/evenly around her eye to the lashes with no gaps or splatter marks. Blood from an explosion would not fall this "perfectly" around eyes. For example, folds in the eyelids would block some blood from landing in certain places and eyelashes should have some blood on them but Mara's did not. (01:41:27)
Visible crew/equipment: Sara is at the front door video intercom. As the man from the Department of Sanitation is leaving, you can see crew/equipment visible in the reflection. (00:27:15)
Continuity mistake: The sizes, locations, and smoothness of the pieces of glass remaining in the wall mirror after Aidan smashes it with a bat change. Initially, there were a few large and several smaller jagged-edged pieces around the top and upper-half of the right side. Later, there were four relatively large smooth-edged pieces spaced around the upper half of the mirror - one in each upper corner and one on each side at the middle. (00:15:48 - 00:19:33)
Continuity mistake: The kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
Factual error: TV reporters said "home invasions" and mentioned trying to find the people who were responsible for the "70 robberies." Lance (in prison), was talking to a woman who was going to write a book and told her he got "twelve years" for "fifteen counts of robbery and vandalism." The crime Lance and the rest of the group were committing fits the legal definition of "burglary" in Illinois (basically, entering an occupied structure with the intent to commit a felony or theft inside; the structure does not have to be occupied at the time of the act). Because there happened to be someone at home during their last (intended) "burglary", this offense would be classified as a "robbery."
Factual error: The film consistently mistakes Absinthe ban with Thujone ban. The United States Food and Drug Administration (US FDA) lifted the ban on Absinthe in 2007, 13 years before the events of this film. Thujone is still banned, and Absinthe products must contain less than 10 mg/kg Thujone content.
Continuity mistake: When Jung-seok returns to the cabin after the zombie outbreak has started in it, there is a shot of him walking past a support pole. The next shot is a POV angle of Jung-seok walking through the cabin. The following shot then shows Jung-seok walking past the same pole a second time. (00:07:08)
Character mistake: Jean rolls, kneads, and flattens the dough a few times, repeating the steps to give the image of still preparing the dough. After the dough was flattened, it was well-shaped (round, higher, and more compact) then flat again. The way she was shaping the dough suggests she was making biscuits, but biscuit dough should not be handled that much (or the biscuits would be flat and not flaky). (00:18:00 - 00:19:00)
