Continuity mistake: Venus' starts off with a burger in her left hand which immediately changes to a watermelon segment, while a cookie has now appeared in her right. She puts the watermelon down only for it to reappear in her left hand when the camera changes angle. The cookie has now disappeared. The camera switches again to show that the watermelon is no longer in her left whilst the cookie has returned to her right... which is swiftly replaced by her half-eaten burger. (01:07:00)
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)
Factual error: Dr. Boxer is told the experimented upon baboon died. He asks that an autopsy be performed. Autopsies are performed on humans. A post-mortem examination on animals is called a necropsy. (01:01:45)
Continuity mistake: Leonardo DiCaprio's phone is shown attached to his car dashboard. He gets out of his car, all the while, looking up toward the sky. The next scene shows him grabbing his phone from his pocket while standing outside his car. (01:36:06 - 01:36:56)
Deliberate mistake: Louis says to his opponent "Glock 17, 17 rounds." The opponent says back "I lost count." In modern semi-automatic handguns, especially Glocks, after the last round is fired the slide stays permanently open till a new magazine is inserted and slide is racked, or the slide stop lever is manipulated (depressed down). The slide can be closed on an empty magazine as well by the slide stop lever. (01:11:00 - 01:11:30)
Continuity mistake: At the diner, the straw in Bobby's (and Jay's) glass changes with the camera's angle, usually being on his side, but on the opposite side when there's a side-front view of Malik. The ice also stays in the bottom of the glass. (01:30:14 - 01:30:47)
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.
Audio problem: When Russo drives off in his Tesla, you hear the car revving and gear-shifting, despite being electric. (01:04:58)
Revealing mistake: At Wendy's 50th birthday party, the helium balloons did not move, even when her daughter Liz walked next to some of them while carrying a birthday cake with lit candles. (00:01:44)
Continuity mistake: A back view of the group of four-wheelers starting out driving through the field showed distinct tire tracks in mostly low, dry brown grass. Various other views showed little or no discernible tire tracks, tall lush green grass, and mixed dry brown and green grass. Even though the four-wheelers appeared to travel some distance, the end of the field that was visible from the onset was just reached. (00:21:35)
Continuity mistake: When two officers go to inform Ronald Whitlock (Bruce Willis) about his sons, Ronald shoots his pistol at the Black officer and hits him near his inner right eyebrow. (A large black spot can be seen between his eyebrows.) When the camera shows the dead officer, the black mark is gone and the bullet hole is on his forehead centered about 2" above his left eye. (00:06:40)
Factual error: The Black Watch sergeant major wears a crown over three chevrons, which was the correct rank badge for a company sergeant major until 1915. However, this is at least 1916 (as conscription has started and the men are wearing steel helmets, both introduced in 1916). CSMs had been redesignated as warrant officers in 1915 and now wore a crown on the lower sleeves instead.
Continuity mistake: In the initial view of Billy in the tree ("saved for later" by the leopard sleeping on another branch), his head is hanging face up alongside a tree branch as wide as his head. When the camera zooms in showing the middle of Billy's face, the left side of the screen should be all brown, representing the branch. Instead, there is blue sky down to his eye and blurred tan/brown representing the branch. The brown might supposed to be the dried grass, but Billy has not moved his head. (00:51:25)
Factual error: When the hackers take out Zagreb, Croatia, one shot shows the effect on a train in a subway station. Zagreb has no subway.
Other mistake: Joshua kept on his thick leather gloves (with side stitching, adding width) while playing the piano yet didn't have any difficulty hitting the right keys. The added width to his fingers from this type of gloves should have interfered with his accuracy hitting the notes and keeping the tempo - the part of Chopin's "Nocturnes" he played was allegro (fast). (00:30:00 - 00:31:10)
Continuity mistake: The white gift box was placed on the car's hood near the passenger side front wheel indentation. When the female cop (Valerie) turned around, the box was at an angle, not parallel, to the indentation. (00:02:21)
Factual error: The New Jersey license plate (L928 : 68FT) did not have the proper format (too many numbers/letters and wrong color). NJ standard plates have a letter followed by two numbers, an emblem, then three letters. NJ plates are yellow/gold reflective at the top, fading to white at the bottom; the Jeep's plate was all white (although the plate holder was buff colored at the top and covered up "New Jersey"). (00:05:07)
Revealing mistake: The blemish/mole that was on the right side of Ghost's nose showed up on her left side (and she was not looking into a mirror). (00:57:40)
Continuity mistake: Before opening the door, the "M" on Eric's letter jacket is on his right lapel but on the left when he enters the room, as well as when he exits. (This is separate from the "M" being on his right lapel but on the left when facing the mirror). (00:40:09)
Continuity mistake: The height of the stack of magazines on the coffee table in front of John changes with the camera's view. Front views of John show a high stack of maybe 15 magazines. Side views of John show a much shorter stack of several magazines. (00:25:03 - 00:26:07)
