Other mistake: When the protagonist is making the exchange via the BMW and tries to slip the Algorithm into the passing car (himself), the window of the car is up, so there's no way he could have thrown it in. (01:19:55 - 01:33:55)
Other mistake: *Spoiler Alert* The strength of the underwater suits is wildly inconsistent. Rodrigo's suit almost immediately cracks and implodes, killing him. Paul's suit is easily ripped open by the creatures, also killing him, but Norah is repeatedly slammed into the sea floor by one of the creatures and her suit remains remarkably intact.
Suggested correction: It is stated by one of the survivors that one of the helmets was damaged. Rodrigo had the damaged one.
Actually, that's not completely accurate. She says something like "Faulty, I knew they were faulty." That also doesn't account for the fact that the creatures tore Paul right out of his suit, but couldn't seem to do the same with Norah.
His suit was faulty. He noticed a crack when he first picked it to put it on.
Other mistake: Vaughn was sleeping in the back seat of the van with his head leaning on Gina's shoulder. When the collision occurred, his body somehow straightened up and went head first between the front bucket seats, through the front windshield, and he was ejected/killed. Based on his sleeping position in the van, he should have rolled forward and been kept in the back seat by hitting the front seats. A sleeping person is also less likely to be injured/killed because the body doesn't stiffen preparing for impact. If the accident actually happened as portrayed in the movie, Vaughn's body should have had visible cuts and be covered in blood, not just have a small amount of blood coming out of the side of his mouth.

Other mistake: The Volvo the woman is driving has a front Oregon license plate numbered 643 ODS, but her rear license plate is 902 CSM. (00:02:55 - 00:03:45)
Other mistake: The email that starts it all for Sid Straw, the announcement from the University of Pennsylvania that he has been chosen to serve on the reunion planning committee, starts off with a nonsensical sentence that no one from U Penn would have ever typed. It's obviously the product of a studio runner whose work no one bothered to proofread. (00:01:15)
Other mistake: When Gary is about to test the trap check the bus door on the right: there's a reflection of what seems to be his shirt, but it's a long sleeved wrinkled shirt, not the short sleeved he's wearing. What's even more bizarre: when Gary moves around, the reflection stays completely still and, drumroll, a shot later, from the very same angle, the reflection disappears. Either it was a crew member hiding, or a CGI-made reflection placed to hide some unwanted crew or equipment reflection.
Other mistake: The woman who checked into the Mercer hotel said she thought the reservation was under "Perratti." Bart initially gave her Room 109, but switched to Room 124 - where he had hidden cameras - saying the room was nicer and had French doors that gave access to the pool area. The woman's husband, expecting to meet his mistress, went to the French doors and knocked to get inside. He should have gone to the room that was initially assigned because he could not have known Bart switched to Room 124. (00:08:52 - 00:10:05)
Other mistake: The opening credits show a bit of Ava's rather extravagant biography. She is involved in a DUI accident that kills two people; the news article says that it happened "early Thursday morning." What follows is a police photo labeled 06/27/95, a Saturday. Then we see the police report; not only the incident time is 10:30 PM, but the date is March 15 1999, which was a Monday. It is not separated incidents, since the police photo is then shown again, next to the "Thursday" article (and the fact described in the article is life-changing). (00:08:10)
Other mistake: If Grace had Billy at age fifteen (without his father in the picture), has worked as a receptionist in a law firm, and undoubtedly had been missing a lot of work due to her failing liver, her house and furnishings would be well beyond her means.
Other mistake: Jude would not be able to write that neatly - especially that fast - while holding a floppy notebook in the air. The right half of the notebook was sagging while he wrote three perfectly lined rows ("I told you not to make him mad."). (00:46:03)
Other mistake: After Jim shot the doe and found it lying in the snow, there were no visible deer tracks or dripping blood trail leading to the doe. (00:01:25 - 00:02:05)
Other mistake: Isaac was able to break through his wrist restraints (taped to arms of a chair), escape two androids, quickly find and escape with Sara (while other androids started pursuing) - during a "full security lockdown" in a facility previously unknown to him. Isaac would not know the building's layout or where doors - and an exit - would be, but he had little problem getting out during lockdown while numerous people and androids were chasing him.
Other mistake: Alpha was standing at an angle to the senator when he shot him in the forehead, but the bullet hole was not angled as would be expected. Alpha was also holding his gun slightly upward when aiming at the senator's forehead, but the majority of the (odd-shaped) blood splatter behind him was near the back of his neck instead of higher. All blood splatter went behind the senator, but some should have been in front. (00:21:05)
Other mistake: Jack took Illinois licence plate "BL 91021" off a Subaru SUV to put on the group's truck and put "V 986394" on the Subaru. Illinois truck (< 8,000 pounds) plates have the letter "B" on the middle-right side of the plate. The "BL 91021" would have too many numbers to be valid. By putting a license plate starting with "V" on the SUV - without the letter "B" on the middle-right side - the SUV would not have a truck plate like it should (and would also have too many numbers to be valid). (00:22:49)
Other mistake: Near the beginning of the movie, John's neighbor, Ed, is standing behind a wooden fence that is diagonal across the screen. The fence behind Ed is straighter. The angles of the fences indicate they are too close together - perpendicular sides of fences do not form a "V." Also, two BACK sides of fence are shown. Since Ed is within the fenced area, it is his (not John's) fence and the front ("good") side of the fence should be facing John's yard.
Other mistake: In the opening scene where Joey is breaking into Ms. Dillard's house, he quickly smashed a window with his flashlight and immediately crawled through the window - without checking to see if shattered glass fragments were still in or around the frame. Despite his carelessness, he did not even get a cut on his hands or elsewhere, which would be almost impossible under the circumstances.
