Other mistake: When the three main characters see the composite sketches of themselves on the news, Chris Hemsworth says "Oh shit" in his natural Australian accent.
Continuity mistake: When one of the robbers is walking away with 4 bags stuffed with money, you can see a large stack of money bills sticking out of the bag. In the next shot the bills are gone. (01:04:40)
Factual error: While measuring the Electromagnetic Field (EMF) being given off by Stonehenge in the film, a scientist exclaims that the frequency is increasing to over 100 Gigahertz, and is approaching radioactivity. This is absurd. EMF is radiation of electromagnetic waves over a wide spectrum of frequencies. Its strength depends on the frequency at which it is measured, with no relation to radioactivity whatsoever. It has a magnetic and an electrical component, but no nuclear breakdown as such.
Other mistake: The protagonist is still a kid, and she is telling in voiceover about all the things she vows to renounce hoping to have her dad back in health. On the porch she knocks repeatedly on the wood, but the magical numbers don't appear. (00:05:00)
Other mistake: They already stated nobody had TV when the young couple were flirting. Then as the tornado is about to hit the family home Dad rushes to get daughter Sam to go to the basement, and she is playing in front of the TV which appears to be broadcasting the news. Not to mention, if the TV was working, wouldn't most people be watching the news for info?
Continuity mistake: When Charlie is coaching Sam in baseball at the beginning of the movie, they get on the road and he beckons to him. In the first cut, people in the background change (most obviously, a guy is crossing the street behind him, but vanishes in the second shot). (00:07:45)
Revealing mistake: When John gets his "birthday wishes" from the crazy 8, you can see he is wearing a black pair of jocks under his sleep shorts.
Other mistake: In the middle of the movie, there is a scene with the two moms on the couch talking. One mom (red hair lady) wears a necklace with a charm that says "love." There are two camera shots in this scene, one looking directly at her, and another from over her left shoulder. Depending on the shot, the 'love' charm is either visible or tucked under the top of her shirt. This swaps back and forth.
Visible crew/equipment: When Mister and the Boy are keeping watch in the woods, just after Boy asks "What are we going to do when the baby comes?" They heart a noise and stand up, as the camera follows Mister you can see lights in the distance, even though they are supposed to be alone in the mountains. (01:20:00 - 01:21:00)
Continuity mistake: The fan on the duty desk stops and starts randomly between camera shots. (00:54:10)
Factual error: If there was that much of a famine in the pack, the Omega wolves would surely have already died of hunger.
Factual error: A delightful movie that theoretically takes place in the vicinity of Portland Oregon, over a period of many months. The problem is, that at no time does it ever rain, and anyone who has lived near Portland knows it rains half of the year.
Factual error: When the Senator is looking at the rent ledger, there are entries for each property as well as the date that money was collected. One of the dates is 2/29/74, yet 1974 was not a leap year. The only leap years in that decade were 1972 and 1976. (00:56:30)
Revealing mistake: After exercising, Valerie is in bed watching the news, then the scene changes to a shot of her house showing a Honda Accord at the 2002 meeting but this model did not get released until 2008.
Continuity mistake: When Stern is cutting Gutterman loose and they're at Rachel's desk, Gutterman is right behind Stern, close enough to touch the desk and sets his hat on it. The shot changes and Gutterman is now further away, not even in arm's reach of the desk.
