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 Vera is speaking with the surgeon as she is washing her hands, whilst she asks "What happened with Ms Blanco", the camera switches angles mid-sentence to focus on the surgeon, and her mouth cannot be seen moving during the last part of the line. (00:12:55)
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.
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.
