Continuity mistake: When the police knocks at the door of Simon's trailer, Jean-Hugues Anglade 's arm changes position between shots as he talks to his daughter.
Visible crew/equipment: When Zoe walks into Anderson's office and tells him she's meeting Maya at the apartment, just as Zoe says, "Uh oh," there's a visible blue T-mark taped to the floor. (00:49:05)
Continuity mistake: In her temper tantrum, the Empress throws various dishes and cups to the ground. In her messy motion though, some items do not fly off the table and a golden fruit bowl happens to just spin around and stay on. It is gone next. (00:02:45)
Continuity mistake: Some figurines on Lidya's nightstand changed positions near the start. The rabbit was moved closer to the front, then back. The blue object was moved back a couple inches. (00:03:15 - 00:03:58)
Factual error: Three men are having beer one night in the woods. One man says he has a picture of a girl he took the previous Tuesday. When he goes to get the picture (which would be on his phone), he complains that he can't show it because there is no signal reception. You don't need a signal to show a photo you took on your phone. (00:07:10)
Continuity mistake: When Elisabeth's mother and sister are speaking with the doctor, as the doctor says "In an institution, yes", Elisabeth's mother's hands can be seen virtually still. When the shot cuts, her hands are suddenly moving around while she speaks. (00:14:50)
Continuity mistake: Valeria went to the first meeting with Alberto Rak at his place. In the following scene her mother Amalia enters her apartment bringing breakfast. Between takes Laura Morante picked up the tray from opposite directions, since the coffee cup switched from left to right during her walk from one end of the corridor to the other. (00:10:50)
Revealing mistake: The anchor rope around Maddy's neck is loose enough for her to remove.
Continuity mistake: In the opening scene with the skype call, Mia's hair is in front/behind her shoulders depending on the camera angle, with no logic. (00:00:55)
Continuity mistake: Ron Perlman and Famke Janssen are having dinner on his supposed birthday. The whole meal has several continuity errors, with her fork being at different heights, sometimes replaced by the wine glass, etc. (00:34:30)
Other mistake: During the murder in the stairwell, an old woman opens her apartment door outward, and Varg kicks it shut. Apartment doors always open inward, as did Euronymous' apartment in the same building.
Suggested correction: Euronymous' apartment door opens outward into the hallway, at least in the final scene it does when he's trying to get away from Varg.
Other mistake: Even if it is a small-town police department investigating the circumstances of Don's disappearance and later discovered dead body, it is not likely that they would fail to conclude (based on forensics), or at least highly suspect, that he did not commit suicide and his death was not an accident. The police should've been able to ascertain that the angle of the gun shot in his mouth could not have been self-inflicted. Also, the blows to his forehead (from Kassi) would arouse suspicion. (01:34:01)
Continuity mistake: When Willy is in bed looking at photos with the camera behind his ear, his cup of coffee is directly in front of his hands. A moment later when the camera shifts to in front of him, his coffee is way off to his side, nowhere near his line of sight. (01:00:12)
Other mistake: During the bank robbers' drive to the meeting spot, the background was blurred, but it is obvious the green color was from the tree leaves. As they got closer and arrived, the numerous trees were bare of leaves - only branches could be seen. The apparent attempt to have all trees appear to be bare (and consistent) was all for naught - It was April 8th in Georgia where the trees would have already blossomed. (00:02:24)
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)
Revealing mistake: The bottom third of the left-hand side of the screen is a "filler." At the top part of the left-hand side, there's a bicycle hanging on the wall, a square wall shelf, and a 3-Light Tree Floor Lamp. About two-thirds of the way down the wall, there's an inverted image of the items at the top - the angled edge of the wall (which does not line up with the rest of the wall because it's inverted), half of a bicycle wheel, the square wall shelf, and 3-lights of the floor lamp at the bottom of the pole. (00:01:54)
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: Vera opens a tape case in a position where the tape is on the left-hand side. The shot then cuts and the case has rotated with the tape now being on the right-side of the case. (00:26:55)
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 orchids in the vase in the center of the table are spread differently in views of Erasmus or Paul. (01:11:12)
