Continuity mistake: The Virtuoso backed his car against the stable at the farmhouse, and the passenger side was aligned approximately with the inner side of the white support beam. After the Virtuoso removed weapons from his trunk, the car was further to his right - about a foot away from the white support beam. (01:05:07 - 01:05:38)
Revealing mistake: When "Snowball" is sleeping on Lena's bed, it is obviously a "stuffed double" (stand-in). Snowball is usually partially hidden behind the dog (so breathing doesn't need to be shown/mimicked). The failure of Snowball to make even a slight movement is a giveaway (e.g, no ear movement when Lena starts talking), but even the stuffed lion, in itself, is not a very good replica - it simply looks fake. (00:33:44 - 00:48:20)
Factual error: Charlie gives Kaz a flare gun to shoot a shark in the mouth underwater. She manages to fire it underwater and the flare travels several meters. It is impossible for a flare gun to activate underwater. And if the flare was fired into the water it will only travel one or two feet. (01:13:00 - 01:18:00)
Revealing mistake: The "bridge" within the crime scene tape is obviously a prop. It should be a continuation of the road, but it is tilted to the left and is more vertical (around 45°). The bridge isn't even very high. When Byron and others go under the bridge to look at the dead girl, there is only a few feet above their heads (clearance under the bridge). (00:04:54)
Factual error: A negotiator is supposed to be neutral and detached (objective), but the divorce negotiator was biased in favor of lawyers Maggie and her father Paul. Even though the negotiator said, "We're all here for the same reason. We want what's best for the child", he totally failed to consider the biological father's (Jeff's) parental rights and Jennifer's right to see her father. Jeff pointed out, "I don't think it's fair she [Maggie] gets a fancy, mean negotiator just because it's her dad [Paul]." (00:09:36 - 00:10:04)
Factual error: He grabs a Glock handgun and a suppressor and begins threading on the suppressor. For this to work in real life, the handgun would need a threaded barrel which extends half inch past the end of the slide. The one he grabs, the barrel is flush with the slide, no threads. (01:05:35)
Factual error: The movie largely takes place in California during the 1990s. California's mandatory seat belt law went into effect 1/01/86. When Mickey was driving Kyd to the cemetery, they were not wearing seat belts. Also, Kyd was 8 years old at the time. Although legally permitted to ride in the front, it is advised that kids sit in the back seat for safety. Considering Lyla was recently killed when a driver ran a stop sign, Mickey should have been more concerned for Kyd's safety as a passenger. (01:12:58 - 01:15:05)
Factual error: The aircraft launched to destroy the city of Miami are F-22 air superiority fighters, which are entirely incapable of saturation or carpet bombing. Even the way they carry out the operation in the movie demonstrates this. They blow up a few streets and that's it. What was the point?
Factual error: Although it's a commonly used movie trope, cutting the brake lines on a bus would not produce the effect seen in the movie. Buses use air brakes, which by design, can operate even with substantial loss of pressure and often engage automatically if there is too much pressure loss.
Revealing mistake: The "unnatural seam" (line) across Jimmy's forehead and beyond - as well as the overall appearance of his head - indicates that he is NOT "naturally bald"! His "fake" bald head was not put on nearly as well as those seen in numerous other movies. [The actor playing the character does not have much hair in real life, but he also doesn't have that artifical line across his forehead.]. (00:07:13)
Other mistake: "Boogie" was a HS student who didn't work and lived with his financially strained (heavily in debt) parents. The Chin family was receiving past-due notices for various bills. The IRS also sent a letter of intent to levy or seize their property if they did not immediately pay $4,513.29. But Boogie had money to buy marijuana, go out to dinner with his girlfriend, go to a gym, and visit a fortune teller - each multiple times. His mother also ate out and saw a fortune teller. With what money? (00:10:20 - 00:28:57)
Continuity mistake: While waiting for her audition, Finley's blouse is loosely tied above the waist, with two flaps hanging like a bow. When Finley gets onto the platform, the knot is tied tighter in the front and the two flaps overlap (look like one), hanging similar to a short tie. (00:17:05)
Factual error: After the HEAVY rain and losing his supplies during the storm, Max (Royce's adolescent son) told his sister he needed to find two very dry pieces of wood to be able to make a fire. Everything in the woods would have been soaked, but Max quickly found two "very dry" logs and was able to make a friction fire (in record speed).
