Other mistake: The white horse looked very uncomfortable from what appeared to be an improperly placed bit (too far back and/or misaligned in its mouth). The handler should have noticed something was wrong and intervened. (00:20:30)
Other mistake: In the distant view, there is a field but no trees close to the pilot's side of the plane right after Jason lands, but there is a row of pine trees nearby when Sam and Ben are standing on the opposite side of the plane. There is also a wider view of the field (with no trees close to the plane) when Jason, Sam, and Ben start walking. (00:11:27 - 00:28:27)
Other mistake: The men went to Flynn's suburban home, with houses nearby on both sides (and probably on the opposite side of the street), at night and many loud gunshots were made inside as well as outside, but no neighbors turned on lights or were disturbed. Dogs did not even start barking until the shooting stopped and Flynn was driving away. Even if neighbors heard but did not want to risk getting killed, the dogs should have started barking at the first sound of gunfire (if not when the men arrived). (00:26:08 - 00:27:49)
Other mistake: The crate, which had gaps between the boards, was buried about 8-10' deep, but it was free of dirt when it was being hoisted out of the hole. (01:14:25)
Other mistake: When Pinocchio transforms into a donkey the foam on the beer he holds is always stable instead of slowly disappearing as it should.
Other mistake: It didn't make sense Catherine was a Catholic preacher but worked at The First Baptist [Protestant] Community Church" and drove a van with the same on it. (00:31:00)
Other mistake: In the origin story of Poirot's facial hair, we see the damage on his cheek is massive, well into the cheekbone. His girlfriend says he'll grow a moustache to cover it, and surprisingly, it works - nevermind the fact that scar tissue wouldn't grow hair. When we see the scar without the moustache, while smaller than the initial damage, it still extends into the cheek at the level of the nostrils in a way that the 'stache couldn't seamlessly cover like in the rest of the movie and its prequel.
Other mistake: In the last scene at the airport, extras get reused - for instance, when she says "I promise..." a guy with a loud teal T-shirt, dragging a little trolley, walks by her. The commissioner offers to give her a ride, and the same guy is walking in the opposite direction. (01:20:50)
Other mistake: Whilst questioning Dani, Carmichael gets a text alert and immediately takes out his phone and looks at the text. The time on his phone is 10:48, but the message is shown to have been received at 10:45. Three minutes did not pass in between the time he got the text alert and the time he looked at the message, only a couple of seconds had passed. (00:51:20)
Other mistake: Maisie rides her bike down the snow-covered hill, but when she stops in front of the cabin there is no snow in or on the tire treads and the tires look dry. (00:12:23)
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)
Other mistake: When Marilyn is standing on the subway grate and the skirt is billowing up, there is one of the takes where there is a dark spot near the front of the skirt. All others are spotless.
Other mistake: Visser was face-to-face with Omar when she shot him in the neck (looked more like it would be in his mouth before the camera shift) yet she did not get any blood splatter on her shooting hand, face, or clothes. There also wasn't much blood on Omar considering he was hit with a near-contact if not actual contact shot. (00:45:41 - 00:47:12)
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.
Other mistake: Si was kneeling on the floor, stabbing his upper left arm and blood was gushing out. After he moved his right arm with the bloody knife to his right side, the aerial view did not show any blood on the floor, across his thighs/pants, or even dripping down his left arm. (00:27:50)
Other mistake: The GPS voice said, "Your destination is on your left", but Kath kept driving (slowly) on the dirt road and did not reach the cabin for over 30 seconds (longer than would be expected). A GPS system typically announces how many feet until you reach your destination, plus "You have reached your destination" after traveling that number of feet. (00:05:00 - 00:05:38)
Other mistake: When Tess says good night to Keith, the lights in the bedroom are on, but the switch is down (off position) but when she wakes up in the middle of the night, the lights are off and the switch is still down. We see a lamp on the same side as the switch but even if she turned it off manually, being plugged into that AC outlet would mean the lamp would probably be off based on the switch. If the switch was up in both shots, it would be different.
Other mistake: When Briggs returned to his SUV after drinking in a bar, he lowered the tailgate and there was no visible rear window. (This was before the window was smashed with a rock). (00:23:49)
Other mistake: Harry is typing on the keyboard, then reading off the computer screen what he writes. When the screen is shown, it appears to be off and, therefore, no print is visible. There is a reflection of light in the upper lefthand corner. (00:21:45 - 00:22:28)
Other mistake: Samantha orders a pizza around 8:20 PM, which is to be delivered within 30 minutes. Lester comes down Samantha's steps around 10:05 and various time-consuming events occur (e.g. Samantha scuffles with Lester, somehow gets Lester zip-tied in a chair, and Samantha starts torturing Lester). Blair, "Cheezy Pizza" deliverer, approaches and knocks on the door. There is no mention of the pizza taking so long - closer to 2 or 3 hours than 30 minutes - to be delivered. (00:08:27 - 00:32:25)
