Continuity mistake: When the waiter puts Lily's "Cleopatra Special" plate in front of her, the long, white, curved ingredients (bean sprouts?) stick upward across her plate, but none are visible or sticking out in alternating views of her plate. (00:08:30)
Continuity mistake: As the SUV pulls off alongside the curb, there are trees with orange-coloured leaves on both sides, but the leaves are green when the ladies are talking in the stopped SUV. The leaves from the tree that is about 15' from the curb are right outside the passenger-side windows. (00:10:15)
Continuity mistake: The clock on the wall at Pee Wee's Pawn Shop advanced from about 12:00 to 12:05 when Frank was talking to Jerry, but it was back to around 12:01 after a few camera shifts. (00:05:59 - 00:06:24)
Revealing mistake: Jimmy's [Matthew Lawrence] glass of cola on the table is filled to a level slightly above the groove (mortar joint) in the cement block wall. The next front view shows the top of Jimmy's glass slightly above the same groove and the level of cola is about 2" below the groove. A little later, the level of cola in the glass is like it was earlier - slightly above the groove. A cement block wall is stationary and nobody raised or lowered the table; use of a green screen can explain the anomaly. (00:08:05 - 00:08:41)
Continuity mistake: Stan (Grandpa) gets impaled in his upper left arm by the metal jack part. The front of his jersey's short sleeve is saturated with blood, almost to the orange stripe near his shoulder. Helen goes to see her dad's injury, and Stan's upper shirt sleeve and shoulder are free of blood, but the lower part and his arm are covered. (00:12:09)
Continuity mistake: When The Artist is talking on the phone to Detective Mary Kelly, sometimes his long, wavy hair behind the phone is flat and other times fluffy (extending wider than the phone). (00:14:45)
Other mistake: Virgil drives the truck across flat land, yet the dashboard and A/C unit atop it are angled at about 45°. Views of Keith in the passenger seat show a level/horizontal dashboard and A/C unit, like they should be. (00:17:12)
Continuity mistake: After Art yells for Jesse to come to eat lunch, the stick of butter on the plate is roughly parallel to the edge of the table, but is diagonal when Art and Jess come to the table. A later view from the other end of the table shows the stick of butter parallel to the edge again. Some of the family members take a roll out of the basket, but none take any butter (so did not move it). (00:20:45)
Other mistake: When everything is moving in slow motion, to indicate how fast Black Adam is supposed to be moving, one of the mercenaries throws a grenade from a distance that is shown moving faster than the lightning moving through the bodies. It reaches Adam before the truck he just ripped apart starts to fall.
Suggested correction: The grenade isn't moving faster. Black Adam is moving towards it, he closes the distance. You see it only turns twice before he grabs it and gets to ground level, shove it in the guy's mouth, and then he's back in mid-air in the next shot.
Watch the scene again. Black Adam isn't even in the shot when the grenade is moving faster than everything else. The grenade is moving away from the guy that threw it. He's even moving as fast as the lightning.
Continuity mistake: The clock on the wall behind Carl when he is pushing the wheelchair to Bess' room is at 11:58. After Carl puts Bess into the wheelchair and is pushing her down the hall, the clock is at 11:45 (or, possibly, 9:00). (00:14:08 - 00:15:40)
Continuity mistake: Although Adeline has her mouth to the ground (eating grass), her head is suddenly upright and still in a few views of Kay or Terry. The most noticeable sudden change in Adeline's head being upright occurs right after Adam hugs her. (00:34:34 - 00:35:00)
Continuity mistake: Simi enters the bedroom and the upper half of the bedspread is smooth. Aunt Claudia is holding a book with both hands, so she is not touching the bed. The front (somewhat aerial) view of the bed shows that the upper part of the bedspread has multiple ripples. (00:17:55 - 00:18:42)
Continuity mistake: The amount of alcohol in the glasses changes. Most noticeable is Senator Mathis' glass going from about 1" to at least twice as much when he got up to leave. (00:06:32 - 00:06:57)
Continuity mistake: When Harry wrapped Lily's ankle injury, there was bloody wrapping below the duct tape. When Karl asked to see Lily's leg, there was no blood showing on the material below the tape. Also, Harry did not completely cover the ankle injury with duct tape like he did to keep creatures from smelling the blood on Lily's stomach cut, questioning why the creatures could not smell the blood on Lily's ankle. (00:19:55 - 00:26:50)
Other mistake: Food products used for a snowman's eyes, nose, and mouth (olives, cucumber, and ketchup, respectively) do not stay intact or unchanged over a 1-2 day period, if at all. [The idea is too absurd to categorize as a "deliberate mistake."] (00:48:33 - 00:57:00)
Continuity mistake: Jenna takes one red cup from the 3 stacked next to the higher stack and returns the two cups to her left (and left of the higher stack). Jenna uses her left hand, supported by her right, to handle the bottle of wine, but the 2 cups disappear after she sets the bottle on the table. (00:19:50 - 00:20:14)
Revealing mistake: Luke points a flashlight along the side of the staircase, but no shadows are produced on the wall from the vertical posts. Luke points the flashlight in front of himself and produces his shadow on the wall behind (and the shadow doesn't look like the way he is holding the flashlight). After Luke goes through the entryway aiming his flashlight ahead, a circle of light is behind him. The power is out, so the flashlight is the only light source - except that used for filming in the dark. (01:03:00 - 01:05:25)
Revealing mistake: The guy with the sunglasses changes from behind and in front of shots. (00:09:46 - 00:10:15)
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)
Continuity mistake: When Maren is reading the letter her mother wrote for her, in a close-up shot of the letter, her right thumb is beneath the letter and her right index finger is above the letter. In the next shot, her right thumb is on top of the letter and her right index finger is beneath the letter. (01:22:24)
