Factual error: Following the blowout, Sara's phone is shown several times as being connected to Wi-Fi with a full Wi-Fi signal. Being in the middle of nowhere, surrounded by hills, it's highly unlikely there would be a public Wi-Fi connection for her to connect to.
Other mistake: The film takes place in 2020. However Lin's fake passport expired in 2015.
Other mistake: When the Polish police officers are shot in the van, there is no blood splatter at all. Two seconds later there is blood on the wall. When the guy in the middle is shot in the chest, blood sprays almost one meter above and behind him on the wall. (00:33:25)
Character mistake: Henry believed his call to the Saratoga County Help Line #1-518-555-0121 was not effective because Glenn's brother George was the Social Services Director. The genius failed to look above the county level and discover there's a STATEWIDE CPS number that he could have turned to #1-800-342-3720. A call to the State CPS hotline probably refers calls to the relevant county, but Henry could have used what he wrote in his notebook "Why Calling Child Protective Services is not a plausible option." (00:28:56 - 01:01:11)
Suggested correction: It isn't clear what number Henry called. He had the county number underlined on the brochure, so I assumed that was the number he called. However, I replayed that part and the person who answered said "Child Protective Services." There was another number above for "National Help Line for Victim Advocacy" 1-800-555-0199, but that's not the National Child Abuse Hotline.
Visible crew/equipment: When the police woman falls off the boat when the shark hits it, on the right side of the screen, you can see a hand outstretched, as if reaching out to grab her. It doesn't belong to the only other person on the boat, since he's behind the wheel and completely out of reach. So, it belonged to a person who wasn't supposed to be there.
Character mistake: Aunt Dottie, pointing to Will's Range Rover, said, "You're not taking that thing out tomorrow, are you? That thing's gonna get stuck before you can get started. You take the Ridgeline. That'll handle anything up there [mountains]." A Range Rover has great capability in all types of terrain and is rated as one of the best off-road SUV's - more than can be said for the Honda Ridgeline. (The movie is not classified as a comedy). (00:11:40)
Factual error: The man cutting through the door is pictured holding a torch, but that type of torch is not a cutting torch. You also see a showering of sparks as though a grinder is being used. (00:42:00 - 00:43:00)
Continuity mistake: Alison is saying goodbye to her parents and she is wearing a long kimono. As she walks into her bedroom she is no longer wearing it, and then picks it up off her bed and puts it on. (01:07:05)
Continuity mistake: When Nicholas Cage and his kid are enjoying a flashback, the ice lolly keeps shrinking and growing throughout the conversation. (01:14:00 - 01:15:00)
Continuity mistake: During the Memorial Day toast, Katie's hand is on and off the glass between shots. The level of wine in the glass also changes inconsistently. (00:12:20)
Continuity mistake: During the initial briefing, the digital clock initially points the time pretty accurately, but then gets stuck on minute 56 for way too long; it's at 12:56:35 when they whip out of the drug lord's folder, 20 seconds of dialogue elapse till the clock is shown again at 12:56:47, another 25 before it gets to 12:56:55, and about 40 seconds before it gets to...12:56:56. And barely 30 seconds pass before Estrada arrives, at exactly 1 o' clock. (00:12:30 - 00:14:30)
