Continuity mistake: Jane Curtin is teaching to a rather seasoned class. One of those old hags says sarcastically "Because we really never do anything." As she says it, notice Eleanor turning towards her momentarily. She then turns completely, facing the opposite way, but at the cut she is repeating the turn from the beginning. Moreover, Moira's mouth closes after she says "Enough!" but the following shot on Curtin shows her still jaw-dropped. (00:04:05)
Deliberate mistake: The oval mirror was in a depressed wall yet was able to reflect a window within the adjacent depressed wall. (00:18:23)
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: The amount of dirt on Neil's face is inconsistent. When he is lying on his stomach, there appears to be a line of dirt along his jaw line. A little later, he has three lines of dirt on his cheek - like someone used a dirty finger to smear dirt vertically halfway down his cheek, then make a diagonal line of dirt partially overlapping, followed by an almost horizontal line across the bottom of his cheek. Also, the sunburned forehead, face, shoulders, and "V-neck" that Neil has before he gets up is largely gone thereafter. (00:04:32)
Character mistake: Bart is sitting on a bench outside the hotel. After Detective Espada talks to the Mercer hotel manager/owner, he goes to talk to Bart. Bart has blood on both hands and lower left sleeve. Detective Espada is supposed to be investigating a fresh murder case that puts Bart at the scene, but he does not confiscate Bart's bloody clothes, conduct a gun powder test on Bart's hands to check for residue, or take him to the police station for formal questioning. Espada did not follow police protocol. (00:17:36)
Continuity mistake: The direction of the desk lamp's flexible neck varies with the camera's angle. Front views of Rodger show the top of the neck aimed toward the outer edge (length) of the desk and rear views of Rodger show the top of the desk lamp's neck pointed toward him sitting at the desk. (01:02:00)
Continuity mistake: The grilled cheese sandwich was charred while it was still cooking, but not when Jason's dad served it to him. (00:02:00)
Continuity mistake: Daryn starts running/jogging in summer foliage. Autumn foliage is shown in an aerial view, then it switches back to summer and Daryn is running on the street. When Daryn says "bye" to Ms. Murdoch, there is spring foliage behind him but summer foliage behind him when the camera shifts. It is one timed-running session and he is wearing the same clothes. (00:01:30 - 00:02:28)
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: When Joe Dalton is driving Jenna and Mara to pick up the drugs, a few yellowish-white flowers are dangling in front of him, but seem too far to the left (toward the driver) to be hanging from the rearview mirror. However, views from the back of the car to the front do not show any flowers. After Joe "explodes" and Jenna is trying to get into the driver's seat, there is something hanging from the rearview mirror (possibly a pine tree-shaped air freshener) that was not previously there. (00:31:39 - 00:32:25)
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: When they lock Tommy in the port-a-potty, they put a sign on the door. The sign is crooked when he keys go off it. In the next cut, the sign is straight. (00:12:30)
Factual error: After sleeping in and being late for practice, Jack is driving to the gym. It is supposed to be morning yet the shadows made by the sun show the sun is setting over the ocean and therefore evening.
Continuity mistake: In the first shot of the choir (three students harmonizing on a note) the girl in pink holds the sheet with her left hand at the corner and the right hand in the middle. Cut to the wide shot, and she has the left hand in the middle and the right hand at its respective corner. (00:03:50)
Factual error: TV reporters said "home invasions" and mentioned trying to find the people who were responsible for the "70 robberies." Lance (in prison), was talking to a woman who was going to write a book and told her he got "twelve years" for "fifteen counts of robbery and vandalism." The crime Lance and the rest of the group were committing fits the legal definition of "burglary" in Illinois (basically, entering an occupied structure with the intent to commit a felony or theft inside; the structure does not have to be occupied at the time of the act). Because there happened to be someone at home during their last (intended) "burglary", this offense would be classified as a "robbery."
Continuity mistake: Whilst Jung-seok is driving with his family on the first day of the zombie outbreak, after he says "All other roads must be blocked", his sister looks to the left to face her son in the back seat. The shot then cuts to focus on Jung-seok, and the sister can now be seen looking straight forwards out the window. (00:01:45)
Continuity mistake: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff. After continuing the story for about two minutes, the length of the ashes still have not increased when Amanda is about to take the third puff. (00:37:21 - 00:39:53)
Continuity mistake: Theodore rides once the tiny rollercoaster; the cart comes to a full stop and his left foot is in the space between the bars, but in the next shot the left foot is on the outside. (00:48:00)
Continuity mistake: Theo lays Susanna's phone down - when it cuts back to her phone is lying in the opposite direction.
Factual error: It would not be possible for Kyle to see the woman breast-feeding - and certainly not as shown. Kyle was driving an SUV in the left lane and Swin was the front-seat passenger. When a car was approaching the SUV from the right-hand lane and the rear passenger area was approximately side-by-side at the SUV's passenger window (which is DARK-TINTED!), Swin looked toward the car, but his face was right in front of the frame around the windows - he would, at most, see the woman's left shoulder... and the baby was feeding "on the right." I doubt Kyle would have been able to see any part of the woman when he turned his head to look. At most (and this is unlikely given the height of the SUV), he might have gotten a partial glimpse of the woman's left shoulder and only after the car she was riding in was in front of the SUV's windshield (but still in the right-hand lane).
