Other mistake: The construction of a staircase does not require a large nail at the site shown on the steps. Furthermore when Emily snags her clothes basket on the stairs it lifts a small nail up. How did it grow into a 2 inch fat nail?
Other mistake: The hurricane winds blows cars around, but the actors can walk against the wind and climb cellphone towers. Plus the hurricane "eye" hits the town, but trucks ride out on a road with dry leaves and dust.
Other mistake: When Benji takes off the Wolf Blitzer mask, he continues to talk with the anchorman's voice until he takes off the voice altering tape too, but when Walker realises that he is not talking to Solomon Lane and proceeds to rip off the mask, Benji talks with his own voice without taking off the tape.
Other mistake: When the detective sends the traffic cam footage, a Gmail alert pops up. However, the dad is currently using Margot's computer, not his. He previously logged into Margot's gmail account on this computer so any alerts received would be Margot's mail, not his.
Other mistake: Sister Irene digs father Burke out of his grave in a crisp white night gown but doesn't get any dirt on it.
Other mistake: The movie takes place in Cincinnati Ohio. Subtitles state the robbery is in July. At the end of the movie the subtitle states "6 months later" which would be in January, but the scene shows short sleeves, no coats, and sunshine. There is no sunny, short sleeve weather in Cincinnati in January.
Other mistake: During the Honeymoon Montage at the beginning of the film, there's one moment where Christian and Ana are on The Fair Lady boat and Ana's wearing a spaghetti strap shirt/dress and Christian's wearing a blue denim shirt. This would if not later on in the movie we see Ana slipping on this shirt and Christian in the blue denim shirt, AFTER the montage scene even though it hasn't happened yet. This is even more evident by a deleted scene - The Hickey/Apology Scene - which takes place just before Ros called to tell Christian and Ana about the fire at GEH. So, basically, they wore these clothes before it was actually shown in the movie.
Other mistake: For the most part we see Malorie floating in the boat going with the river. However, numerous times we see her rowing against the tide. Even blindfolded you would be able to tell you are rowing against the flow by the resistance on the paddles.
Other mistake: As York is entering Dave's apartment, and Dave is guiding Miles to the secure room, the entry door of the apartment appears to have only a chain lock and presumably a door knob lock. Standard stuff for apartments, and Dave surely is not relying on this for security or awareness, but It seems inconsistent with the high-tech and defense-first nature of the movie. (01:26:30)
Other mistake: At the end of the movie Lorraine has to remind Elise that she helped her once, implying they haven't seen, or spoken since. When Elise first meets Josh in the 1st insidious she tells Josh that her and Lorraine have been friends for a long time, implying they talk or see each other regularly.
Suggested correction: That's debatable as the word "friend" does have to do with semantics. I have friends I have not spoken to in a long time, or speak with rarely, but still consider them friends due to our history. Others would say that's not a friend as that's not what they think of when they hear the word "friend." So it does depend on the individual person. It's also quite possible this is what they told Josh as the cover story for why she was contacted since they initially didn't want him to remember his past.
Other mistake: Dominica breaks her left leg and then holds her crutch (and the golf club) in her left hand. This is a frequent Hollywood mistake. If you are using a walking stick or a crutch, you hold it on the strong side, then the natural swing keeps it in sync with the injured leg and improves balance.
Other mistake: At the very beginning when Riley shots the dude in the head, the blood comes out but the bullet does not break the glass.
Other mistake: While Amy speaks with Bilel through Skype, each time Bilel is in the Internet cafe the same guy is sitting behind him.
Other mistake: While "dead" Mike is bent over his car's engine, his left leg moves. (00:32:40)
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: The man who shows Kurt around the Dusseldorf Art Academy (and later becomes his friend) introduces himself as Harry Preusser, but during the end credits, his name is listed as Gunther Presseur. (01:54:25 - 03:04:00)
Other mistake: The remaining four people at the power plant are evacuating ahead of the explosion of the bomb they set. They are running towards the helicopter to escape. The scene shows the helicopter with the rotors already turning. But there is no-one on board, much less a pilot to have started the helicopter. (01:21:10)
Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.
Other mistake: When Tyler is in the bathroom brushing his teeth, he is facing a wall-sized vanity mirror. The mirror should not be able to reflect the window along the adjacent wall (along the right side). Also, regardless of what angle of Tyler the mirror is reflecting, it reflects the same image of the wall. (00:30:26)
Other mistake: In the close-up of the gun freshly printed, there's a bunch of molten plastic by the gun cylinder and the grip. Waikiki retrieves it right away, bare handed, and the bed is completely clean too. (01:03:25)
