Sarah doesn't have her camera ready when John throws the football, yet on her website there is a sequence of photos of him throwing the football.
When John and Nicole make out in the water (about 5 feet deep) at the beginning of the movie, they are far away from the other people at the beach party. When John's leg starts glowing, she has to swim to shore and then run to the other people; but, in the video from the website, they are in shallow water (2-3 feet deep) and the person filming them is apparently quite close as the video is very clear and close up.
When the Mog lifts John up by the throat with his hand, his thumb and forefinger rest on John's jaw. When John speaks to him, the Mog's hand is suddenly much lower, but in the subsequent shot the hand is back in its original place.
(at around 29 mins) When John is standing in front of his open locker, three students walk by him in the background. In the next hall scene, the students have suddenly vanished.
When John and Nicole make out in the water, she speaks of the Big Dipper constellation and both look directly up. In Florida, the Big Dipper would be closer to the horizon.
The bulk of the movie takes places in Paradise, Ohio; however, the law enforcement officers' uniforms and vehicles are not from Ohio.
Floor buffer continues running when it has no one operating it. They won't run unless someone grasps the handles.
John is not human but Loric. The way things work in his body may not be the same as a human, so the scars on his legs could theoretically stay the same. Also, scars are not guaranteed to shrink as one ages. As he grows and his skin stretches, it would make sense that the scar would grow and stretch in a similar manner, especially if the scar is burned into his skin in a size relative to the size of his leg at the time.
When returning to Ohio from Indiana, John and Sam stop by a rail track to assist Henry, an AVR (Allegheny Valley Railroad) train passes them. The AVR services Pennsylvania (which is where the movie was shot) does not run in that area.
Despite the fact that John had not answered his phone for three hours, Henri does nothing about it and does not even mention it at all afterward.
Sarah uses old, mechanical cameras, such as Nikon F, yet never focuses before shooting.
