Deliberate mistake: The front passenger's side mirror [driver's side is on the right] is parallel to the screen/camera yet there is a perfectly clear image of the passenger's face looking into the mirror. (00:00:38)
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)
Factual error: The accident takes place the night of July 18, 1969, and they show there being a full moon. That night the moon was actually waxing crescent with only 14% visible, and set at 10:27pm while the accident happened about 12:45am, so there was no moon in the sky anyway.
Continuity mistake: Kate at the beginning of the movie asks Demerius, the kid who is reading a manga, to read some of it loudly for the whole class. When she addresses him first, the book on his desk changes position between shots, repeatedly. (00:01:20)
Continuity mistake: Man-seob smears some cream above his upper lip after a few smoke grenades are deployed. The amount of cream shown over his upper lip changes between shots.
Visible crew/equipment: When Detective Hole enters the murderer's cabin you can see somebody running in the snow outside.
Continuity mistake: Maggie gets downstairs while Henry and her daughter are playing with their phones. The hair goes in front and behind her right shoulder depending on the camera angle. (00:03:00)
Factual error: Just after feeling the explosion from the south tower, Eddie's watch shows 17:37 whilst others and himself are stuck in the North tower elevator. The planes hit the towers in the morning. (00:35:00)
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: After Hutch is buried, Dominic leaves to catch up to the other two, limping with his right knee held rigid. An aerial shot is then taken showing Dom limping on his left leg instead.
Continuity mistake: At the gas station, Thelma and Ben are talking to random people Thelma thinks she knows. Meanwhile, her family is on the way there. The sun is going down in this sequence and it's noticeably getting darker. Before they run behind the building, it's suddenly lighter outside and gets darker again.
Audio problem: During Beca's performance of Freedom, she is singing with Cynthia Rose. During the little chorus pre-verse (before they put their hands in the middle), you can hear Beca's voice singing the lyrics but Anna Kendrick's microphone is nowhere near her mouth. Her lips don't even match it.
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.
Factual error: In the opening robbery Chuck is sporting a Smith and Wesson model 686. The scene was depicted in 1972. The 686 didn't come out until 1980.
Continuity mistake: Sara recovers the artifact and gets on the boat. She removes the deep-dive helmet and the oxygen tank. The villain is looking at her through his binoculars, she hasn't moved, but the equipment she took off and dropped on the deck has vanished. (00:03:00)
Revealing mistake: Right at the beginning of the movie, an alien blasts Lieutenant Smalls and he drops his rifle. The weapon wobbles, revealing it's a rubber prop rifle. (00:01:55)
Factual error: Since the movie was set in the 60s, David Senak couldn't have gotten in trouble for shooting the man running away. In the 60s, the police could legally shoot any criminal running away. This didn't change until Tennessee v. Garner in 1985.
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)
Continuity mistake: At the beginning of the movie, Regina is looking at pictures and messages on her phone. There's no solid continuity between close-ups and wider shots, with the hand position changing suddenly most times. (00:01:10)
Factual error: At Fort Winslow, the soldier assigned to take Corporal Woodson to the infirmary is referred to as "corporal" and wears a rank insignia of one chevron. A single chevron was not authorized as the insignia of any rank in the U.S. Army until 1920, and even then, it denoted a Private First Class, not a Corporal.
