Other mistake: Rebecca electrocuted the giant sand worm within 3' of the spaceship. After Lt Astrid arrives, some views show Rebecca out in the open, but the camera should have been obstructed by the spaceship because following front views still show Rebecca next to the spaceship. Also, at least part of the dead giant sand worm probably should have been visible at times but was not. (00:51:55 - 00:52:20)
Other mistake: At the Night Driver gallery showing, Haley is reading from a program that describes Anthony's "Say My Name" piece. The text states that Helen Lyle died from "self-emulation" instead of "self-immolation", immolation meaning death by fire.
Other mistake: After the fire extinguisher was sprayed to put out the flame on the wall painting, there should have been some debris or markings to reflect the use of the extinguisher, but there were no obvious indicators. (00:24:50)
Other mistake: The way the man fell onto the hood and then the road, landing on his back, after Sami hit him from behind while going fast defies physics. He also landed too far to the left of the driver's side for being hit with the middle of the front bumper. (00:35:41)
Other mistake: After Finney got off the mattress, he was walking in the dark (at least a few steps). The screen went completely black, but Finney - who had not been in that basement before - was able to reach up and pull the cord to turn on the bathroom ceiling light. (00:29:50)
Other mistake: When searching the missing kids database, the date given for when Malia went missing is 7th January 2021. When Rain receives a text message from Caileb the message is dated April 18 2019. (00:56:11 - 01:13:11)
Other mistake: The bottle of alcohol (whiskey?) and glass on Morgan's bookcase appear to be the same as the ones the Game Master has in his office; the bottle is emptied to the same level (too similar to be a coincidence). (00:03:23 - 00:06:57)
Other mistake: In a weird move concocted for the movie, Carnage creates a tornado spinning around real fast with his tentacle sticking out. Against physics, one of the tentacles gets a hold of the prison chief and keep still for a few seconds while Carnage's body in the background has spun around itself a few times already. (00:38:30)
Other mistake: The time line seemed off. Ken brought his daughters to his parents' house and it appeared to be morning (not dusk). One asked why he had to work on Thanksgiving. When Ken picked up Chris to go to work, Chris' parents were just finishing their Thanksgiving dinner. At work, Marnie said, "I can't believe I missed Thanksgiving with my family..." The group of employees shared slices of turkey luncheon meat - "No one should be without Thanksgiving." The store opened at 9:00 PM - well after dinner.
Other mistake: Rose was upset because she wouldn't be seeing brother Eric after he left for college, so it is implied that the university is some distance from their home. It doesn't make sense that Eric wore a blue high school "M" letter jacket that appeared to match the color scheme and logo of the University of M - (unclear) he would be attending or that he would go to practice in full uniform at his high school football field with friends a mere six days before leaving for college to play football.
Other mistake: Randy is using her laptop to watch Staci on the surveillance camera. It is just past midnight, but the time at the bottom right of the camera image says 12:18 PM (noon), rather than 12:18 AM. (00:42:00)
Other mistake: Sharyn was hooked up to an IV catheter somewhere in her upper arm (underneath her gown's short sleeve). The IV's location is unusual because IV catheters are usually placed in an easily accessible location, such as the back of the hand or forearm. When Sharyn ran out of her room, she apparently ripped out the IV without injuring the injection site or causing any bleeding. After being returned to her room from her escape attempt, she no longer required IV therapy (wasn't hooked up). (00:06:30 - 00:07:34)
Other mistake: Blood gushed out of the bound man's lower inner arms that were slit with a knife from below the elbow to the wrist (then turned toward the ground). A switch to an aerial view showed no additional blood dripping (while he was still alive). Also, blood would not pour out of his arms to the ground in a horizontal stream like it did. (00:02:04 - 00:02:27)
Other mistake: At the end of the movie the soldiers handcuff Farid despite the fact that he only has one hand.
