Factual error: Smaller pieces of the comet start raining down in a highway setting. While small fragments of a comet can come down, they'd all be traveling at anywhere between 20 miles per second as the comet is an extra-solar comet. Those small pieces wouldn't make such piddling explosions, they'd be creating concussion waves that would rupture your organs and send vehicles flying. The heat even from those small rocks would ignite all foliage within 50-100 yards. (01:31:00 - 01:34:00)
Continuity mistake: At the market, Lee picks out five pieces of fruit (one apple and four oranges?), tears a produce bag off, and walks away. He takes a few steps off-screen, and he is next seen going around an end cap and walking down an aisle, with nine pieces of fruit in the produce bag. (00:01:36)
Other mistake: Capt Artemis offers Tony Jaa's hunter character an intact partial Hershey bar that she pulls from her pants pocket. The film takes place in a brutally hot desert that would've turned that chocolate bar into chocolate goo not long after the start of the film. If the heat hadn't melted the bar, it would've been smooshed by the continuous hand-to-hand combat between the two characters. (00:45:22)
Factual error: The Corvette owned by Bentwood is not a Z06 as shown in the movie. It is a 2014 C7 Stingray and can be identified by the Stingray logo on the side of the car.
Continuity mistake: A pile of drugs gets blasted up with powder flying everywhere yet there's none on the ground seconds later.
Other mistake: In The Croods, Guy was handing out bananas and gave one to Grug, which he threw away. But in this film, he does everything to get this mystical fruit that he hasn't had since his childhood.
Continuity mistake: The girl that wanted her bully in high school to be tortured filmed the torturing with an iPhone XR then was later holding an iPhone X before the movie ended.
Factual error: SPOILERS! While the ending of Al being arrested for murder at his own wedding is dramatic and cathartic, it wouldn't have happened that way. There's no way that the cops would have known to search the wooded area near the cabin; they would have needed to find physical evidence linking the cabin to Al; they would have needed to establish that Al had no alibi for the time in question; etc. None of that would have happened that quickly or that quietly.
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)
Continuity mistake: When Marcus sees his baby grandson, a nurse in the background is picking up a white diaper. In the close-up the diaper is now blue.
Continuity mistake: The characters are on a tile floor that has one yellow tile visible among the black and white tiles. The next shot they're in a different spot on the floor with two yellow tiles visible. (01:22:10)
Visible crew/equipment: While on the Genesis, when Robin finds Frank she asks if he's bulletproof, then Alpha 5 contacts ops to open hatch 26, and as Frank and Robin walk over to the monitor, a white T-mark is visible on the floor. (01:20:40)
Factual error: The Blackledges' car has a license plate that starts with 34. Montana uses the first two numbers on their plates to identify the county that the driver lives in. 34 is the number for Sheridan County which is in northeastern Montana where there are no mountains in sight, but the Blackledge ranch is set near the foothills of a mountain range as you would see in western Montana.
Continuity mistake: When the girls are standing on the beach with the flares to guide in the German aircraft they are in two rows just a few metres apart. The view from the aircraft shows them much further apart, wide enough for the aircraft to land between them.
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)
Factual error: Lynyrd Skynyrd's plane crashed in the early evening in October 1977. Injured crash survivor Artimus Pyle, tended to the severely injured people and later was able to walk through the swamp and the woods in the dark to get help, but in the movie when the plane crashes and Pyle's search for help it's a bright sunny day.
Visible crew/equipment: The diner flashback has possibly one of the worst handling of extras ever. The lady behind Crystal Fox keeps glancing at the camera and playing with her food in very unnatural fashion, but it's the guy with glasses behind Mehcad Brooks that truly shines; throughout the scene he drinks from an empty glass and, even more obvious, eats invisible food from his fork, usually throwing a glance right at the camera every time he does so, looking like he's about to crack into a laugh at the absurdity of it. It's such a bad performance that one really wonders if he was trolling Tyler Perry or something. (00:32:25)
Factual error: The USMC Embassy Guard is an enlisted Marine Sgt. He is wearing a Commissioned USMC Officer's cover (hat) that has gold braid and gold oak leaf motifs on the visor. (01:20:15)
Other mistake: In the credits of the movie, the creator of the original comic's name is misspelled as "Bob Macleod" when it should read "Bob McLeod."
Continuity mistake: Tim is showing the Nanny's phone to the others. He plays the message from his parents, but does it tapping the bottom part of the touchscreen, while the media file and its "play" button as established in previous views, is at the top. Likewise, when he turns towards Jane asking "Do you want to be taken care of?" he is pointing at the bottom of the device, but in the reverse shot his finger is at the top. (00:43:30)
