Continuity mistake: The clothes Tyler and Kassi were wearing at Kassi's house were not the same when Kassi came to dinner that day at the Burnside's house. It seems unlikely that BOTH would change clothes before dinner. (00:31:49 - 00:32:40)
Suggested correction: Apparently they did. It was probably Tyler's idea, presenting Kassi in the best possible light to assuage suspicion and maintain his image as a good Christian Boy Scout.
Revealing mistake: Davey at the beginning of the movie is looking at the newspaper he's delivering to Mr. Wayne Mackey. Just from a glance at the page you can tell that something is off, since the article supposedly about a missing boy appears to be written entirely in first person. Upon closer inspection, turns out that it's filler text from chapter IV of Robert Louis Stevenson' s "Treasure Island". (00:01:30)
Continuity mistake: In the van after they pick up Preacher and he mentions it's cold. Preacher leans up to the front and looks over Dax, asking about his head being too big. There are several cuts between shots here before Preacher slinks back into the van and his position of his head and shoulders changes between almost every one in various positions. (00:33:50)
Continuity mistake: Susan meets backstage Dr. Mitch. He states the obvious saying that she looks alike her twin sister, just more confident, and she cuts him off saying that she knows. She was leaning back with her hands as support, and at the cut she replies to him with her hands joined at the front. (00:09:45)
Continuity mistake: A-X-L frequently varied in size. For example, sometimes its head looked massive compared to Miles, being about the size of Miles from his head to waist. Other times, A-X-L's head looked about twice the size of Miles' or Sara's head. A-X-L's body was sometimes about the same size of Miles' motorcycle but much larger other times. A-X-L looked much smaller when it was dragging Sam compared to when it was standing over Sam.
Plot hole: *SPOILER* Calvin's twin sister and mother were killed years earlier in an automobile accident. Calvin kept going to his doctor with "new symptoms", insisting there was something physically wrong. Dr. Collins told Calvin, "Your health issues aren't physical. I thought sending you to that support group would give you a better perspective." The doctor should have referred Calvin to a psychiatrist for a diagnosis and, if appropriate, the psychiatrist would recommend therapy or a support group. (00:10:15)
Continuity mistake: The middle curtain on the passenger side of the RV is pulled open to different extents (toward the sides) when Drake is snooping around. Depending on the camera's view, maybe a foot of the curtain can be seen to the right. The other views show much more of the curtain, indicating it is not pulled to the side as far (and might possibly be closed). When a larger amount of the curtain is showing, there is also a small section of a pleat partially on the sill. (00:04:00 - 00:04:27)
Factual error: When Connor is describing his 1970 LT-1 Corvette,, he says "Holley and Rochester Quadrajet carb." Those are two different brands of carburetors. (01:05:39)
Continuity mistake: On Friday, Lana waves bye to Aakif on the doorsteps; he has both hands on his belt in that first wide shot, but when he replies and waves back, his left hand is in his pocket. (00:09:50)
Continuity mistake: Sparse snowflakes fall in wide shots, but there is heavier snowfall in close-ups of Barbi. (00:29:30 - 00:30:15)
Continuity mistake: Constance is hugging Mary. In the close up shot, Constance is wearing a round sky blue earring. In the long shot, the earring is not seen even though her ear is fully facing the camera. (00:27:45)
Continuity mistake: When the robber is arrested, his hands are cuffed behind his back. When he's being loaded into the police car, his hands are suddenly cuffed in front of his body.
Factual error: When Lukas takes Sarah to school (on Friday or only a couple days after taping his laceration), the laceration is much smaller (practically healed) and there are only three strips of tape. A laceration as wide as the one Lukas had would not heal within a couple, few, or even several days. Also, the way Lucas taped his laceration would not yield the same/similar results as sutures (even closure and faster healing with little scar). (00:15:43 - 00:16:31)
Continuity mistake: After Omar Sy beats up the masked pickpocketer in the Chinese supermarket, he waves the crowd to move on. The stick he has switches hands between shots. (00:04:25)
Continuity mistake: Paolo's wife finds the text message of the girl calling him "my eternal love." In close-up she is holding the phone with the index finger at the very top of the phone, but in the previous and following shots the index is far from reaching that spot. (00:09:15)
Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
Continuity mistake: Abby's annoying boss puts her friend to work giving him a box to carry to his car. In a rather blatant continuity mistake, the penguin is facing opposite directions between shots. (00:03:15)
Factual error: An ambulance is shown. This movie is supposed to take place in a latin country. But the ambulance says "Ambulance" in English, and worse, it also says "Riverside County." Also, the red cross emblems on the attendants' backs say "Comite" in Spanish, "International" in English, and "Geneve" in French. (00:28:55)
Continuity mistake: In the bar scene when Renee sneaks up behind Vivian, she puts her right hand over Vivian's mouth, then has her left hand on top of her right hand while covering Vivian's mouth; and then a moment later in a new camera angle, her right hand is over her left hand. (00:27:00)
Audio problem: When Vera is speaking with the surgeon as she is washing her hands, whilst she asks "What happened with Ms Blanco", the camera switches angles mid-sentence to focus on the surgeon, and her mouth cannot be seen moving during the last part of the line. (00:12:55)
