Continuity mistake: When Sister Irene's habit is ripped at the back, you can see a bra strap on her left shoulder which disappears when she is seen at the front and when the camera is closer to her back (when she has the pentagram carved into her).
Continuity mistake: Jimmy Silva's Hk416 has one surefire M300 scout light on the right hand rail (3 o'clock) throughout the movie, but when he enters the apartment complex he all of a sudden has two flashlights on both left and right rails (9 and 3 o'clock). About 30 seconds later when they begin to engage it goes back to one. (01:08:30 - 01:09:05)

Continuity mistake: Spoiler alert: At the end of the movie "Rose" stabs "Miles." We see her pull out the knife and it looks like a Rambo-type hunting knife. After she stabs him, we see the knife covered in blood but it is a different type of knife. It looks more like a skinning knife or filet knife.
Continuity mistake: This mistake is apparent after watching A Quiet Place 2. At the start of the movie when the family are at the store, a New York Post is visible on the newsstand with the headline "It's Sound." This would suggest that the invasion didn't hit the town immediately and that they had time to have newspaper deliveries and actually put them on sale. However, in the second film, it was evident that civilisation was pretty much destroyed on day one.
Continuity mistake: While Casey and Morris are video calling, Casey is holding the iPad perfectly and then suddenly it turns upside-down in a later shot. (00:13:35 - 00:14:42)
