Audio problem: As Annie is trying to leave Joan's house and she starts to give Annie instructions on how to do the ritual, it's obvious the audio for Joan's lines was dubbed in in post as a lot of her speech doesn't quite match up with her lips. Especially when she's saying "Your whole family needs to be in the house". (01:08:00)
Audio problem: Malory ejects all of the shells in the shotgun to show she knows how to operate it, but the audio clip is of empty shotgun shells hitting the floor.
Audio problem: When the nurse at the hospital tells the family that Elisabeth was transferred two days prior, Waltraud says "Transferred? That's impossible" and doesn't say anything else. The camera then changes angles to focus on the nurse and Waltraud's mouth, visible in the left hand corner of the frame, can be seen moving briefly, even though she already finished the line and didn't say anything else. (00:29:17)
Audio problem: When Nico goes to Angel's house, he is confronted by a dog barking at him. The dog is shown aggressively moving its head up and down whilst the camera is focused on it. The camera then cuts to focus on Nico, where the aggressive barking is still heard, but the dog is standing completely still. The dog couldn't have been barking that aggressively if it were standing still; the barks were likely dubbed in. (00:05:12)
Audio problem: When Donnie is grabbed after leaving the Federal Reserve there is an audible sound like a fence is being hit, but the concrete barrier is front of the fence, and Donnie is never seen pushed into the fence.
