Continuity mistake: Mikey and his friend are smoking the same inch-long joint by the back door which gets passed back and forth - no way they could keep holding/smoking it for that long given how short it was to start with. (00:04:50)
Continuity mistake: At the "Wave Hair Salon", Ms. Gordon has a curler/roller at the top of her forehead. In some shots, it is straight, but in other shots it is angled. A little later, Christine goes over to Ms. Gordon and starts rolling down the curler to the top of her forehead as if for the first time. (00:08:04 - 00:08:47)
Continuity mistake: Monica's station wagon and the moving van Jacob drove to their new property in Arkansas are not parked in the same positions moments after their arrival. Initially, both vehicles are at some distance from the mobile home (or trailer) and are roughly parallel. When the camera shifts to a view from the vehicles toward the mobile home, the vehicles are suddenly a lot closer and their front ends are angled toward each other. (00:02:13)
Audio problem: When we are first introduced to Hayden lecturing the classroom, the shots from behind do not match the sound with the movement of his jaw.
Factual error: In the flashback scene to 1985, a shelf with VHS tapes can be seen. Some of these movies date from after 1985 (Dante's Peak, 1997).
Plot hole: After the incident in Chemistry class, Adam was taken to the hospital where he was diagnosed with schizophrenia. Next, Adam found out that he was expelled from school. What happened during Chemistry class was attributed to Adam's "first psychotic break" - which would fall under a medical condition for which Adam could not have prevented or controlled. The Department Of Education has laws protecting students like Adam (Individuals with Disabilities Education Act or IDEA, enacted in 1975), and the school is required to meet the child's / student's needs. An Individual Education Program (IEP) should have been prepared for Adam by his school, so the expulsion served to further the plot. (00:06:00 - 00:06:30)
Continuity mistake: The appearance of Grace's house by the front door (to the left of the screen) changes from the time Billy is standing along the road to when he meets his mother half-way. At first, the side of the house is mostly white; it is mostly brown thereafter. The garage area to Billy's left also changes color from brown to white. (00:05:22)
Continuity mistake: In the lunchroom scene where the bully dumps Peter's chili into his bag; it then flashes to Peter somehow eating his full bowl of chili which was just dumped out. (00:17:11)
Continuity mistake: When Johanna and the Captain are being chased by Mr Almay and his associates, their position in the wagon changes. First Johanna is on the Captain's left. Next shot she is on his right. Next shot she is back on his left. (00:42:14)
Audio problem: During the talk of the three Glorias, the teen Gloria's mouth isn't in sync with what she's saying.
Continuity mistake: There are some continuity problems during the cafeteria scene where Fern is being introduced to her co-workers. Fern is holding a banana, peeled almost to the bottom, and has several slices of banana on her peanut butter sandwich. There is another banana peel on her paper lunch bag. Fern is shown taking a bite of her sandwich. A little later, Fern is holding a partially peeled banana but no slices can be seen on her sandwich. If this is her second sandwich, she already peeled two bananas. (00:05:59 - 00:06:32)
Continuity mistake: The protagonist receives her gift from Molly Shannon. She unwraps it and puts the discarded wrapping on the counter. When we see it again at the end of the scene, the wrapping is much less torn apart than the first time around (or at least has been arranged neatly). (00:09:45)
Continuity mistake: Tommy had a cup of coffee in front of him when he met Jaylene at the outside table. After Jaylene showed Tommy the picture of him and Sandy, the coffee cup was to the right of the ashtray and closer to Jaylene (as though it was hers). Also, the mini creamer cups that were on the saucer appeared to be gone. (00:07:17 - 00:07:54)
Other mistake: In the opening scene where Joey is breaking into Ms. Dillard's house, he quickly smashed a window with his flashlight and immediately crawled through the window - without checking to see if shattered glass fragments were still in or around the frame. Despite his carelessness, he did not even get a cut on his hands or elsewhere, which would be almost impossible under the circumstances.
Continuity mistake: During the introductory meeting with Nicole Kleiber, her glasses on the desk switch back and forth between open and folded. (00:26:20)
Continuity mistake: Towards the beginning of the flashback, Jahkor gets thrown to the ground. The legs of the bully in the close-up cast a shadow over Jahkor's body. Cut to the next shot, and the shadow is away from Jahkor in a blatant change of direction of the light of the scene. (00:09:35)
Continuity mistake: The number and location of the blue gas containers that fell out of the rear of the station wagon change. Initially, three containers fell out. Only one was visible on the road and it was to the side of the rear bumper, not on the road where it fell/ landed. Next, no blue containers are visible on the road, followed by one container being behind the passenger side rear tire. No blue containers are on the road when the goat comes out. (01:00:14 - 01:00:36)
Revealing mistake: Near the beginning of the movie, there does not appear to be a curtain (or window) on the left side of the screen (e.g, when Samantha is sitting on the couch), but there is near the end when Chloe enters the now-empty room. The use of a green screen seemed apparent throughout the movie. (00:04:19 - 01:23:04)
Continuity mistake: The first time we see the girl the main character fawns on, people on the background keep changing between shots during the beach volley game. (00:08:20)
Revealing mistake: Vic jumped onto the roof of the white van while it was moving. The van driver started weaving to get Vic off the roof - but Vic could not be seen at all when there was a front view of the van. Even if Vic were lying on the roof, at least part of him should have been visible. (01:04:04)
