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: 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: 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: 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: 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.
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: 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: When Glass is walking around the sub before leaving Scotland we see 2 men in their bunks. Just as the camera pans in to look at them, a third man in the corridor can be seen to stand aside and let the camera pass before continuing. Captain Glass is not near this sailor at the time. (00:08:50)
Other mistake: After Steve slides open the middle window near Olivia, a small puff of air and some small waves of the right curtain panel can be seen, but not nearly as much or strong as would be expected. The left curtain panel was largely stationary. With the window completely open, the right and left panels of the thin curtains should be blowing inside the RV at an angle or even be flapping outside of the RV. (00:10:45)
Other mistake: When Earl is walking toward his seat in the auditorium's third row at the "Glam Cosmetology Graduation", up to four seats can be seen in rows #2 and #3, but five seated graduates can be seen in row #1. Row #1 is closer to the camera than the other rows, so four or fewer graduates should be visible in row #1, not five. (01:07:20)
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.
