Other mistake: During the dinner Slowik reveals that his restaurant does not have nor serve bread of any kind. Towards the end of the movie Margot requests that he make her a cheeseburger, which he does. Where did the buns come from?
Suggested correction: I just watched through the scene. The chef never once says that the restaurant has no bread. He only states that the guests will not be getting bread as part of this specific meal plan. Furthermore, we actually see a plate of bread at the start of the course, the dude-bro customers ask for bread since they know the chef has it, the notecard specifically discusses the bread that was made at the restaurant but won't be served, and another customer actually even specifically notes that the restaurant is known for their high-quality bread. Every single indication is that the chef absolutely has bread and is simply withholding it due to the theme of his dinner that night.
Suggested correction: He didn't say they didn't have bread. He stated THEY wouldn't get bread for that evening, since it's a common man's staple, and they are not the common man. So, they get a breadless bread plate with nothing but dipping sauces.
Other mistake: It is unrealistic that Solomon could drag the long rope through a wooded area for years without the rope getting frayed/worn out and that the rope did not get snagged or caught in shrubs, around tree trunks, etc.
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)
Other mistake: The plea deal with Danny (5 to 7 years in prison) seems inconsistent with Georgia's sentencing guidelines, recidivist law, and the State's reputation as being tough on repeat offenders. Danny was on parole, which means he was convicted of a felony. His new charges - including assaulting a police officer (an "aggravating circumstance") and possession with intent to deliver - could be enough to impose MAXIMUM sentences or mandatory minimums (10 years?) under sentencing enhancements.
Other mistake: At the end the camera bulbs would not work as they are electric. This is proven when the music starts after the creature leaves the area. (02:01:00)
Other mistake: Abraham's wife appeared to hit him with the vase on his right shoulder, but Abraham put his hand on the side of his head. (00:58:35)
Other mistake: Laura's Arizona license plate (G 652P) was, understandably, a combination or blending of the design from Jan 2008 - Apr 2020 (blue/white/yellow horizontal colors) with a serial format closer to that of the mid-1950s, but improper for either time period. The 2008 - 2020 plate serial format was "ABC 1234." Laura's 1955 plate - when the serial format was "A - 12345" - should not have had a letter ("P") on the far right. ("G" could be the code for Gila, Graham, or Greenlee County, but which one?). (01:24:19)
Other mistake: It had been (acid) raining for some time and a puddle along the curb was shown with brown (Fall) leaves in it. If the acid rain was dangerous enough to eat away human flesh, it should have been powerful enough to erode/destroy the fallen leaves soaking in the puddle full of acid rain. (01:02:10)
Other mistake: Jamie was strangling Rose with both hands, quite forcefully, for almost a minute until his dad hit him over his head. When Rose was getting up, her neck was not the least bit red and did not show any signs of having been choked. (01:05:05 - 01:06:03)
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: 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.
