Other mistake: In the frame you can see the girl is playing on a newer Macbook, she is using a wired headset but the headset is not plugged into the laptop, you can also see she is using a wired gaming mouse, and the USB cable is just sitting there not connected to anything. The Macbook is USB-C only and the mouse is USB-A.
Other mistake: If Grace had Billy at age fifteen (without his father in the picture), has worked as a receptionist in a law firm, and undoubtedly had been missing a lot of work due to her failing liver, her house and furnishings would be well beyond her means.
Other mistake: After Jim shot the doe and found it lying in the snow, there were no visible deer tracks or dripping blood trail leading to the doe. (00:01:25 - 00:02:05)
Other mistake: Based on where Carol is standing near the top of the stairs of her new apartment, more of the couch behind her should be to the left of the screen (like it is in a later shot). (00:48:10)
Other mistake: Mike has a spycam in the locket, but Isabel tears it off his neck. However, the device immediately stops working. Unless the 5' woman crushed the actual metal instantly in her fist, it should keep working and broadcast at least the audio, even if she snapped the cord free. (01:39:25)
Other mistake: The time freeze dome extends well beyond the little Italian square and covers the surrounding buildings as well. Everybody and everything is paralyzed/suspended, but a gramophone in a window looking directly at the square continues to play. (00:34:03)
Other mistake: In the scene with a leak in the kitchen, the woman fixes it by turning an isolating tap above the leak. However the water would have been travelling up the pipe to the kitchen tap and so that wouldn't have stopped the leak. (00:34:00)
Other mistake: On 22's name-tag wall some of the names repeat themselves. Yossi Mizrahi and Itay Cochabi can be spotted twice, once towards the center and once towards the right side of the screen. There might be more.
Other mistake: Ava disposes of her target and reports her Executive code (74598CG). Then she gets as reply from her handler "Management code 840227." Later we see Duke's management code, and it's different (96729CF), which is also the one she types on the plane.
Other mistake: Jung-seok's nephew accidentally drops a ball which rolls away and lands in front of a nearby bed. When he walks over to get it, he realises that the man sitting on the bed has turned into a zombie. He is shown in a contorted position, with his back lifted off the ground and is heard making painful grunting noises. The other passengers in the cabin then realise there is a zombie in the room with them. It is extremely hard to believe that none of the other passengers in the cabin would have noticed this beforehand, not even by accident. This man's body was in a completely inhuman and unrealistic position, but it's not until the nephew walks up to him where people start to notice. (00:05:25)
Other mistake: Interior views of Joe's car while he is driving Jenna and Mara to pick up the drugs are somewhat odd or awkward. The driver's seat is pushed back, leaving a lot of space to the steering wheel. When Jenna is getting into the driver's seat, the headrest (or back of seat?) is enlarged and tilted about 45° inward. When Joe put the wipers on, they appeared to be moving BEHIND the flowers which were dangling on the inside. The blood splattering from Joe wasn't as could be expected. (00:31:27 - 00:32:31)
Other mistake: "Sally" the Great White Shark rammed Emma into a rock (or other hard object) underwater and Emma only got a small cut above her right elbow. It isn't clear how fast Sally was swimming, but Emma was rammed with force (and appeared to hit her back). A female Great White Shark weighs about 4,000 or 5,000 pounds, so Emma would be expected to suffer a major (not minor) injury under the circumstances. (00:05:24)
Other mistake: The weapon which the gunman is holding is a WWII era Nazi MP38/40 submachine gun. The weapon from the magazine housing to the end of the barrel (muzzle) is completely bent down about 25-30°. There's no way the weapon would shoot as straight as it was shooting earlier if at all. I highly doubt the firing pin/bolt can even make contact with the primer of the bullet in the magazine. The weapon looks cartoonish if anything. (00:48:30 - 00:50:00)
Other mistake: Isaac was able to break through his wrist restraints (taped to arms of a chair), escape two androids, quickly find and escape with Sara (while other androids started pursuing) - during a "full security lockdown" in a facility previously unknown to him. Isaac would not know the building's layout or where doors - and an exit - would be, but he had little problem getting out during lockdown while numerous people and androids were chasing him.
Other mistake: Jude would not be able to write that neatly - especially that fast - while holding a floppy notebook in the air. The right half of the notebook was sagging while he wrote three perfectly lined rows ("I told you not to make him mad."). (00:46:03)
Other mistake: When Lomito was holding the little green ball with the smiley face on it, her flashlight was shining on her fingers/fingernails - all of which were long and manicured. The length of her fake fingernails - even if they did not exceed the department's policy on maximum length, such as one-fourth inch past the fingertip - probably were long enough to interfere with her ability to quickly put her finger on her pistol's trigger and shoot; the length interfered with her ability to perform her duties. (00:31:25)
Other mistake: When the kid first leaves and enters the house, he takes out the crossbow with an arrow in it but the elastic drawstring is flapping around in front. (00:22:33)
Other mistake: When the white mouse runs to save the brown mouse, he runs at normal speed, but the witches move in slo-mo for reasons unknown. (00:47:23)
Other mistake: At the beginning, Jack reveals that he has lots of food allergies and asks the bartender to prepare his shake lactose free, implying that he is allergic to dairy. But later he eats a snowman cookie that Mrs. Claus reveals has butter in it.
Suggested correction: Being lactose intolerant does not mean you're allergic to dairy. It means you lack the enzyme (lactase) needed to break down lactose and usually results in gas or an upset stomach. However, butter is high in fat and low in lactose, so a lot of lactose intolerant people can eat butter or food containing butter just fine.
Other mistake: Jack took Illinois licence plate "BL 91021" off a Subaru SUV to put on the group's truck and put "V 986394" on the Subaru. Illinois truck (< 8,000 pounds) plates have the letter "B" on the middle-right side of the plate. The "BL 91021" would have too many numbers to be valid. By putting a license plate starting with "V" on the SUV - without the letter "B" on the middle-right side - the SUV would not have a truck plate like it should (and would also have too many numbers to be valid).
