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: 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: While Daryn is talking/rapping to Isabelle in the Creamery (ice cream shop), the distance his black earbuds dangle along the zipper in the front of his hoodie vary. At one point, only one earbud is visible. (00:15:00)
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: 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: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
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."
Factual error: Rich told Jamie, "There was a car accident. Guy came in. I cut when I should've stitched or stitched when I should've cut. I don't even know. His family sued in civil court, and I lost everything." A doctor working at a hospital would have been required to carry malpractice insurance, which would have protected him from "losing everything." Also, it would be difficult to prove that a car accident victim who died during surgery was a victim of malpractice; most cases are settled out of court. (00:38:30)
