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.
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."
Factual error: The soldiers had 506 Regiment's helmet markings of the 101st Airborne, and on their sleeves the 82nd Airborne and 1st Division shoulder patches.
Factual error: The USMC Embassy Guard is an enlisted Marine Sgt. He is wearing a Commissioned USMC Officer's cover (hat) that has gold braid and gold oak leaf motifs on the visor. (01:20:15)
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.
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)
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: Mara's hair is inconsistent during the prom - the length and tightness of curls varies a few times. Most noticeably, the sides of her hair sometimes only reach her shoulders but other times look three or four inches longer (and this is not merely due to loosening of her curls). (01:14:20 - 01:16:06)
Revealing mistake: When the black cat was going up the staircase and got to the first landing, it turned its head to look directly at the camera, then continued climbing the staircase. (00:08:13)
Audio problem: During the talk of the three Glorias, the teen Gloria's mouth isn't in sync with what she's saying.
Continuity mistake: In the opening scene, the blue car is parked on the far right of the screen or at least one car length from the doctor's front door. Dr. Huggins says goodbye to the couple with the baby, who walk toward their car. After the burglars-to-be (turned robbers) are shown watching from a distance, the camera returns to the doctor's front door. The blue car is now near the center of the screen and it drives away toward the right of the screen - going past the place it had been parked.
Continuity mistake: First argument. Leilani shouts "Why are you being so loud right now?", with a hand behind her neck. She does not start the next shot in that position, she puts her hand there only a second later. (00:04:05)
Continuity mistake: On the train, Margaret's hair had a distinct uneven, broken part (the middle section running parallel to the first and third lines), but her part was linear when she got to work. Also, in the hallway, some hair was raised near the back of her head in front views but not in rear views. (00:04:15 - 00:04:40)
Factual error: When Jung-seok is trying to get his sister away from her son, he begins shooting at a zombie that begins charging at him, and he falls on his back. Behind him, another zombie is shown with two other zombies lying on top of him. The zombie then manages to stand himself up, with almost no struggle and this also prompts the two zombies to fly off him. This move completely defies the laws of physics. This zombie should have the strength of an average man, and the two other zombies should be of equal, or at least somewhere near, the same weight as him. He was only using his arms and back to stand himself up, so realistically, the moment of him trying to stand up should have taken a lot more strength and a bit more struggle than what was shown. (00:08:13)
Continuity mistake: While sitting on the couch, Peter suddenly has a clump of hair sticking up near the back of his left-sided part that disappears but reappears after some camera shifts. (00:01:20 - 00:01:42)
Continuity mistake: When Oliver is pushing injured Michelle in a chair down the hallway, they are approaching a long row of student lockers. When the camera shifts to a front view, they are near a stairwell and the short walls behind them are cement and brick with no lockers before the door. (00:41:05)
