The spittle on Chris' chin (while he's in the game-room chair) changes between shots.
The scene where Georgina admits to Chris that she tampered with his cellular phone, there is a piece of lint located in his hair that eventually disappears.
When Chris and Rose are down by the lake talking, Chris's eyes are red and full of tears. Less than 10 seconds later, they are completely dry, without a trace of moisture or redness.
The first night at Rose's parents' house, Chris moves the stuffed lion facing outward. When he wakes up, the lion is looking towards the bed again. Later in the day, during the party, the lion is facing away from the bed again.
Chris stands up with his hands up at the 1:38:38 and continues standing at 1:38:40, 1:38:48, and the 1:38:54 marks; then reappears at the 1:38:58 mark getting up from a a *prone position* and walking until 1:39:04 without ever having his hands in the air.
Transportation Security Officers are not federal law enforcement officers and do not drive airport patrol cars as they have no authority outside of an airport security checkpoint - they do not have arrest authority, carry no weapons, and are not permitted to use force.
Losing to Jesse Owens in the qualifying rounds of the Olympics would not have prevented Roman Armitage from making the finals. Up to three runners from the same country can make the finals if good enough.
Real bingo cards have only 1-15 under B, 16-30 under I, etc. The bingo cards in the movie have many out-of-range numbers.
At the end of the movie, when Rod pulls up in the "TSA vehicle", while properly displaying a "DHS" license plate, the driver's door incorrectly displays the seal of the state of New York.
When the white car struck the tree there may not have been airbags to deploy, as was previously suggested. The Porsche 944 was produced from 1982 to 1991 and airbags were not introduced until the 1987 model year. If this was an earlier model that was used in the crash it might not have had airbags so no airbag deployment during the crash might not have been an error.
Chris' phone died while on the phone with Rod, after showing him the picture of Andre. Though he never recharged it, it is implied that the Armitages did it at some point as later Rob and Rose talk through Chris' phone, that way he can later use the flash.
When Rose's car hits the deer, the deer is moving from left to right, so it would seem the driver's side would be damaged. However, the deer is leaping high in the air at the point of impact and hits the front passenger side, thereby causing damage on that side.
It may be thought that striking the deer would have caused greater damage to Rose's vehicle, but it is impossible to predict the amount of damage hitting a moving animal will do. Also, it was a glancing blow -- hard enough and at the right angle to kill the deer but not hard enough to do more damage to the car.
Rose was looking for her keys to give to Chris so he could put the bags in the car while she said her good-byes, so the fact that she could have started the car as long as the key fob was somewhere in her bag is a moot point.
When Rod searches for information on Andre Hayworth, the second result is a page titled "How to report a missing person." However, in the close-up, the excerpt from the page shows instructions on how to feed a dog.
When Chris sends Rod a photo on his phone, he begins typing Rod's name into the recipient tab. However, even after several letters, his phone screen shows "no name found" in the tab. A suggested contact should have popped up right away.
When Chris is shaving, the razor clearly has no blades since the shaving cream is merely being smeared around his face.
After Rose accidentally hits a deer and then stops her vehicle, the camera lens can be vaguely seen on the car.
When the Porsche pulls away from Andre, there are at least three moving shadows visible on the street (Andre along with crew).
When Rod is talking to Detective Latoya, he says "girl's friend parents' house" when he means "girlfriend's parents' house."
