Continuity mistake: The tattoo artist is almost finished drawing the American flag on the boy's upper right arm. After he wipes it and there's a quick camera shift, the tattoo is less complete - the stripes are bloodier, more jagged, and of unequal width like they were earlier. (00:14:31)
Continuity mistake: The night Krypto loses his powers, he gets a black eye on his left eye. However, the next day, the wound is gone.
Deliberate mistake: While roasting marshmallows, Henry's marshmallow caught on fire with the flame shooting about 6", then a foot+ high. A marshmallow subjected to such intense heat/flame for many seconds would not be stuck to the stick and stay stuck with repeated forceful flicking or "whipping" of the stick like Henry did. When the marshmallow finally flew off the stick and landed on a camper's head (higher than would be expected), it would be small/hard/charred, not large and still soft/white in the middle. (00:35:03)
Other mistake: Visser was face-to-face with Omar when she shot him in the neck (looked more like it would be in his mouth before the camera shift) yet she did not get any blood splatter on her shooting hand, face, or clothes. There also wasn't much blood on Omar considering he was hit with a near-contact if not actual contact shot. (00:45:41 - 00:47:12)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Revealing mistake: The size of the spider walking off Sam's face becomes disproportionately smaller too fast compared to its size while on her cheek plus the spider's awkward movements are indicative of CGI. (00:02:20)
Other mistake: It isn't clear whether Robert's gunshot wound was an "entrance" or "entrance and exit" and if the nurse or surgeon? wearing scrubs committed a character mistake - "We were worried, given how deep the bullet penetrated" but Sasha "heard the bullet passed through Robert's shoulder." "Penetrating" means the bullet entered but stayed inside the body; "Perforating" means the bullet passed through the body. In general, perforating gunshot wounds tend to be less serious and therefore less "worrisome." (00:06:23 - 00:07:42)
Continuity mistake: Laura's hair was (flipped) above her shoulders when she brought Cody to school. When she was in her car, her hair was much longer, going at least a couple or few inches down her back. Laura's hair was back to its shorter length (above-the-shoulders) when she got to the typing room at work. (00:15:44 - 00:16:06)
Continuity mistake: The bite marks on Doc's sandwich were inconsistent/contradictory. Doc took a corner bite out of his sandwich, then the sandwich was shown with an additional side bite mark (made off-screen?). When the sandwich was shown again, the distinctive bite marks were gone and the side of the sandwich that had been eaten was straight across. Doc was holding the sandwich in his right hand; after another camera shift, Doc was holding the sandwich in his left hand and the unique side bite mark was back. (00:18:22 - 00:18:48)
Continuity mistake: The view from the (unseen) car driving toward the distant house on a hill showed fog well above the pine trees, but when the car/limo got to the house/mansion (10 seconds later), there was no fog. (00:02:17)
Character mistake: Nolan said, "Everybody knows that no sharks swim in freshwater" and Spencer said, "They don't come into freshwater", but there are freshwater sharks (e.g, river sharks) and bull sharks (not true freshwater sharks) can survive in saltwater or freshwater. Jacob Harper (National Aquarium) pointed out eyewitness accounts of sharks swimming up the Mississippi River and "bull sharks have kidneys that recycle salt" but did not mention the glands near their tails that help keep salt in their bodies. (00:08:08 - 00:29:50)
Continuity mistake: The way Banshee's bangs are combed back vary a few times in a couple minutes (elevator fight scene). Sometimes, the left side is higher than the right side and other times the highest point is near the middle of her forehead. The "curve" at which the bangs are combed toward the right side also vary, from little to no curve to wavier toward the right. (00:06:36 - 00:07:57)
Continuity mistake: The views of Pinero's dead "trophy wife" from opposite sides of the bed were not consistent. From Seth's view, Pinero's wife was lying mostly on her right side with her hair covering her head/neck but otherwise not visible, and her right arm extended outward from her waist area. From the other side of the bed, Pinero's wife's long wavy hair was over her left breast and should have been visible from Seth's position but was not. The wife's right arm also extended outward from her shoulder area. (00:00:22 - 00:01:19)
Revealing mistake: There's something odd about the chair that is (or is not?) to the right of Monsignor Kelly when Stu goes into his office to talk. Only part of the back of the chair can be seen and it is not directly in front of the Monsignor, but there is not enough room for the seat part to be there (otherwise, the Monsignor could not be standing where he is). Without any indication that the Monsignor or chair moved, the Monsignor is later able to rest his right hand on the chair's back. (01:13:57 - 01:14:37)
Revealing mistake: The $100 bills in the briefcase looked quite fake and were obviously a prop. (00:13:40)
Continuity mistake: When Joey is talking to Voight about the puzzle box and Voight tells him to "Keep going," pay attention. It's kind of hard to notice, but if you look closely, in the over-the-shoulder shot facing Joey, you can tell that Voight is standing straight, facing Joey before it cuts. When it cuts to the opposite angle, suddenly Voight's body has rotated about 90° (to his right).
Continuity mistake: The top of Brecken's head was close to (within a few inches of) the headboard before his mother brought the pillow. When his mother put the pillow over his face and the camera shifted to a right-side rear view, the upper part of the bed was raised about 45°. When Lang Dotrice (Brecken's father) arrived and sat on his bed, the pillow used to smother Brecken was at least a foot away from the headboard and Brecken's head (still under the pillow) was about a yard away from the headboard. (00:04:05 - 00:07:16)
Continuity mistake: Young Norma Jean is shown a photo of her father placed at the head of her bed. It has him facing right and there is a large white defect in the photo at the upper left corner. When the photo is "talking" to her in a succeeding scene, he is facing left, and the defect is on the upper right corner.
Continuity mistake: The amount of Kyle's facial hair changes (i.e, grows too much/fast) from the beginning of the scene when he is on the rock talking to Jaelyn to the end of the scene when he is standing in the water. Kyle's facial hair is back to its lesser amount when he is in the villa; it isn't clear how much time has passed, but it doesn't appear to be much. (00:17:06 - 00:20:28)
Factual error: The owl that JP was looking at made a "who who" sound. The owl may appear to be a Snowy Owl (one many people are familiar with), but it is a Barn Owl. Barn owls are not "true" owls and it is the true owls who "give a hoot." Barn owls don't hoot; they make a screeching or squealing sound which can be piercing (and eerie to some people). (00:32:50)
