- Continuity: Sarah's coke can in the first dinner at the house repeatedly turns round between shots.
- Continuity: The amount of coke in Sarah's glass changes between shots.
- Continuity: It is clearly raining outside, yet when Burnham is in the house, he is completely dry.
- Continuity: Burnham rolls the carpet back to get to the safe twice.
- Revealing mistakes: Meg Altman breaks the mirror with the sledgehammer then walks over the razor sharp shattered glass with her bare feet. But right as she's about to walk out the door you see she's wearing some kind of 'hidden' protection on the bottom of her feet.
- Continuity: After Meg Throws the medical bag into the panic room and Burnham sees it open for the first time the red plastic case that contains the syringe for Sarah is not there, but later it is.
- Continuity: When Meg is taping up the vents, she leaves the bottom of the vent unsealed. But when it shows her taping up the next vent the first vent is taped shut all the way.
- Errors made by characters (possibly deliberate errors by the filmmakers): When Meg starts searching for a "chocolate bar" once Sarah's sugar level drops, Sarah says she had already searched in the box and had found nothing. Yet we clearly see standard U.S. Military M.R.E. (meal ready to eat) packages which include a high sugar ration (in the form of, or in addition to, a dessert with the meal itself and sugar to be used with the included instant coffee), when Sarah was first searching.
- Errors made by characters (possibly deliberate errors by the filmmakers): Sarah was seen drinking from a red Coke can and eating pizza early in the movie. A type I diabetic like Sarah would have been drinking Diet Coke since it is sugar free, not a regular Coke. Therefore the can should have been silver, not red. (Also given the fact that Sarah was eating pizza and drinking regular Coke, both of which are high in carbohydrates and sugars, it is extremely unlikely she would have a low blood glucose level anytime that evening.)
- Errors made by characters (possibly deliberate errors by the filmmakers): Sarah says that she learned the Morse code for SOS "from Titanic", which is commonly taken to mean Titanic (1997). That film does not feature the SOS code. In context of this film, this mistake is made out of panic.
- Errors made by characters (possibly deliberate errors by the filmmakers): When the E.S.U. (Emergency Service Unit) team enters the house and clears the bottom floor officer Keeney calls for a "bus" or ambulance to help Stephen. When E.S.U. are called to a scene an ambulance is automatically dispatched with them, there would be no need for Officer Keeney to call.
- Errors made by characters (possibly deliberate errors by the filmmakers): Junior says that Meg had closed escrow. New York does not have an escrow system. Closing on a house is done with attorneys, with a set closing date.
>>> WARNING: Here Be Spoilers <<<
Goofs below here contain information that may give away important plot points. You may not want to read any further if you've not already seen this title.
- Factual errors: SPOILER: Striking a flame or spark in the flue when there is a flammable gas mixture in it would not result in flame shooting back to the source of the gas, and even if it did it wouldn't result in the gas cylinder being blasted around the room. At best a continuous flame would burn at the point where the pipe joints the duct (after severely burning Meg's exposed arm); at worst, but more likely, there would be a massive blast in the panic room, probably killing the two girls but at least burning them both severely.
- Errors made by characters (possibly deliberate errors by the filmmakers): SPOILER: Flammable gas (propane, butane) is heavier than air. When the villains try to gas Meg and Sarah out of the panic room, Meg says to "keep down" when this is in fact where the gas would go. Staying close to the floor would increase the danger of asphyxiation.
