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: 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: While racing through a parking complex to get to his daughter at the hospital, Lin ramps out of the exit and hits the font of his car on the ground leaving some damage, and even a part of the bumper hanging off. However in subsequent shots, the vehicle is undamaged. (00:02:50)
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.
Factual error: No matter how sophisticated the STEM chip is, it would not enable Grey (Logan Marshall-Green) to go from a completely horizontal position to a completely vertical position in one fluid motion, without bending his knees, and he does this several times in the film.
Factual error: When the bank robbers pull the money out of the vault, they claim all the cash is from 1982. Yet most of the bills have large faces, which was introduced into rotation in 1996.
Character mistake: Set in Texas, the Sheriff threatens the wrongdoer with the gas chamber. Executions in Texas at that time were all by electrocution, namely by "Old Sparky," the electric chair. Texas has never used the gas chamber for executions.
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)
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)
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)
Character mistake: In the highlighted newspaper article entitled 'DeFeo Son Accused' about the killings, the first sentence of the article ends with two periods. Also, in the 3rd sentence, the word 'psychiatric' is spelled "psuchiatric" with a 'u' instead of a 'y'. (00:01:05)
