Factual error: Bill is awakened by a clock radio. The AM frequency shows it goes up to 1700kHz. The AM expanded band was not introduced until 1993. In 1980, devices only received AM frequencies up to 1600kHz. The SONY clock radio in the scene was not from 1980. Plus, the alarm sound it made wasn't popular until the late '90s.
Continuity mistake: After RVD is shot by the lone motorcyclist he goes home to take care of his wound. You can see that he was shot in his LEFT shoulder. When he goes to the bathroom and takes off his shirt, the wound is on his RIGHT shoulder. After bandaging up his wound, he finds his wife bound and gagged and his daughter has been taken. He goes out to the garage and you can see his LEFT shoulder is now bandaged. (00:58:50 - 01:01:55)
Factual error: After warping back from Iscandar, Kodai looks out of the window. Yuki Mori points him where Earth is. A moment later, he responds to the hailing signal saying that they are now 420,000 kilometres from Earth. Considering that the distance between Earth and the Moon is about 385,000km, Earth is looking unreasonably minuscule from their window. (01:52:50)
Continuity mistake: In the classroom, Jarod leaves with Detective Fairchild's business card in his right hand and accidentally (maybe deliberately) left the "Death and Cremation" book on the floor. Courtney picks up Jarod's book, apparently with the intent to give it to him the next time she saw him. Later, Courtney is reading the book and finds Detective Fairchild's business card between pages (like a bookmark). If this was meant to be the one the detective gave to Jarod, it can't be. (00:50:41 - 01:01:05)
Continuity mistake: After the shootout at Sarah's birthday party, White Mike is visited at the hospital by Molly. Mike's pillow has marking "Property of Queens Hospital", they cut to Molly, then back to Mike, and the marking is gone. Regardless, they were in Manhattan, they would not have taken him to Queens Hospital anyway.
Character mistake: Two police officers went to the Davenport's house because someone "requested a drive-by in the middle of the night." The veteran cop rang the doorbell, knocked on the door, heard noise (dismissed as "probably a pet"), and even yelled, "Rise and shine, people." He told the rookie cop that he was "trying to go the extra mile to make sure these folks are okay" and "Somebody called in a drive-by and I want to see their smiling faces." The officers nonetheless left when they got another call. (00:19:19 - 00:20:41)
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: Jason spits blood onto Joker's chin which changes spot wise and shape wise by the next shot.
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: Given that Cassandra's parents are so incredibly rich, spoil her rotten, buy her anything, and have even got her a luxury apartment, why on earth is she flying to the USA in economy class?
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)
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: Blake jumped through the window, shattering the glass and propelling many fragments through the air and towards/onto Edgar and Zoe, but no-one got cut. (00:34:10)
Continuity mistake: The little Nono is singing the nursery rhyme in front of the cafè. One of the nazis tosses him a coin, while the other puts the cigarette down, but at the cut he's already taking a puff.
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.
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)
Factual error: When Luke puts the starting cables on the battery of the pick-up truck sparks fly from the connection. However since he hasn't connected the cables to anything on the other end yet no sparks should be visible. Next to that the battery is nearly dead so there is no power to give the sparks in the first place.
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)
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.
