Revealing mistake: An enraged Cheetah almost literally mops the White House floor with Diana flailing her around with the lasso. Wonder Woman is sent back first into a pillar, which disintegrates from the impact. Very good, but not so good is the other piece of pillar that comes down and bounces like rubber by her. (01:51:45)
Revealing mistake: When Ava holds a knife to the gambling woman's neck, you can see the plastic knife bend.
Revealing mistake: During the dance number in the airport, Santa grabs a security guard who then starts break dancing. It's obvious this dancer is a stunt double as he's younger and skinnier than the real guard.
Revealing mistake: Emmet held a cigarette lighter, displaying a fairly high flame for a long period of time and even held the lighter sideways in his palm without burning his hand! If it were a real flame, he most certainly would not be able to hold it lit very long and would have burned his hand. (00:24:25 - 00:25:25)
Revealing mistake: When the Protagonist and Neil are walking through the Freeport area whilst the plane is being hijacked, just after the worker fills in the numbers on a keypad and opens the door to the vault, he walks through and is followed by Neil. The Protagonist is shown holding a small cup of espresso and briefly looks around before walking in with them. The interior of the cup can be seen when he does this, and there is no liquid inside of it. (00:40:12)
Revealing mistake: When Devil Face cuts J.D's arm the knife's clean. (00:52:47 - 00:53:10)
Revealing mistake: After "Yoga Pants" unlocks a man's mouth gag, the man starts to unlock hers. Yoga Pants bends her head down and the metal rods in the mouth gag expand and slide out of her mouth before it's unlocked. She pushes her mouth gag back in place until the man removes it for her. (00:12:37)
Revealing mistake: The candles on the long dinner table are numerous and clustered, but linear in front views of people seated at the table. Based on how the candles are disorderly arranged, it would not be possible to show a couple or few candles spaced apart in front of one person. (00:05:35)
Revealing mistake: The nefarious villain has just revealed to Prince Charming that he has kidnapped the princess, and shows her to the crowd as a big burly smurfy monster is holding her. The crowd in unison gasps and looks horrified...except an extra who just can't keep a straight face. (00:07:35)
Revealing mistake: Tom drives at least two differently equipped Ford 4x4 Supercrew trucks. In particular, there are two different grille guards, with one being smaller and less protruding than the other, as well as less-menacing looking. Although inconsistently used, the switch to a grille guard that can cause less damage is used at the gas station when Tom runs into the guy who tried to help Rachel get away from him and when ramming the rear-end of Rachel's Volvo. One truck has fog (or running) lights below the grille guard, making the two differently-equipped trucks more noticeable/discernable.
Revealing mistake: Men of the Department of Sanitation are picking up Lita's body from her house. The body bag she is supposedly in moves so easily, you can tell it is very light and contains nothing very heavy, much less the weight of a body. (01:03:05)
Revealing mistake: Initially, the gallon plastic water bottle Joey was bringing to Hamby looked almost full. However, the ease at which he raised it into the air (by his head), "hollow" sound made when Matt took it from him, and the way it tilted to the side when being dropped down the hole are indications that the water (and its weight) had been removed for most of the scene. When Joey dropped a plastic bag containing a bologna sandwich, chips, and a soda pop down the hole, it went straight down without tilting.
Revealing mistake: It looked like Theo's gold and white checked shoes were a few sizes too big and wide to make it easier and quicker for Laura to put them on her, but Laura still had some difficulty slipping on Theo's oversized shoes. The material even folded down around the ankle when Laura was putting on Theo's right shoe. (00:03:42)
Revealing mistake: Eden's (or her stunt double's) dismount from the horse looks real, but her jumps off the platform to the ground are so soft with uneven foot landings that she has to be hoisted down. (00:11:11)
Revealing mistake: When the door is kicked in, it does not sound very loud or like a typical door smashing. An interior view shows the door is about half the width of a standard door and a 3-4' board can be seen falling vertically along the door frame/ wall (then disappears). Instead of hearing someone kicking open a door, the sound more accurately matches what happened: a thin door breaking through a board holding it closed! The "breaking in" scene also has some "stupidities." Stewart (without first trying to see if the door was not locked) uses a cordless drill on the door's lock and a second man then uses his right leg to kick it in (without first seeing if the drill unlocked the door). A third man brought a crowbar, which could have easily eliminated the need for someone to bring a drill or for one of the men to risk a foot/ leg injury by kicking open a door. (00:02:11)
Revealing mistake: When De Niro/Grandpa falls down the roof and hangs on to the drain, he is replaced by an obvious stuntman with a wig and thinner build.
Revealing mistake: Although it appears that Edgar (and later Norman) put his eye up to the hole in the wall to look into the opposite room, the eye is obviously fake. Too much of the sclera (white part of the eye) is showing and the upper eyelid is too far above it; the upper eyelid typically reaches or partially covers the top of the iris (colored part of the eye). Also, the eyelashes go downward instead of being curved upward. (00:18:05 - 00:19:49)
Revealing mistake: In the scene where Dave (Alan Tudyk) is brushing off Sid (Tony Hale) at the reunion, the camera from slightly behind captures jaw movements that don't match his speaking, and he continues speaking when there is no jaw movement at all. (01:47:00)
Revealing mistake: When Millie jumps on her shop teacher's back, the teacher switches from the actor to a stunt double as they begin to tumble about. Noticeably, his hair suddenly gets much darker and has less gray in it. You can also get brief glimpses of his face, and it's obviously not the actor.
Revealing mistake: The backgrounds during the pawn shop scenes often change, suggesting the use of a "green screen." For example, the grandfather clock was behind the clerk to his left, then not there, but back again. Sometimes shirts are hanging in the front windows but other times there are other items there.
