Continuity mistake: In the woods, Agatha picks her locket up from a puddle. Herb calls her because they are going to roll the body over. Look at her ponytail as she turns around; in close-up, it suddenly gets over the coat's collar. (00:03:30)
Continuity mistake: Agatha crouches by the freshly rolled-over corpse, does not touch it, but when the camera pans up and away as she walks off, it changes position (for instance, their arm moved to the opposite side of the "1" tag). (00:03:50 - 00:04:40)
Continuity mistake: At the beginning of the library scene, Agatha/Agnes shows the borrowing card to the clerk. This piece of evidence changes position repeatedly between shots. (00:05:40)
Continuity mistake: Agnes forces Dottie to cooperate by threatening to disturb the quiet of the library. Just before she starts shouting, she puts the card down directly on the desk. However, in the next shot, the card is atop a book. (00:06:05)
Continuity mistake: In the scene with Norm the jeweller appraising the locket, depending on the camera angle he holds it in his right hand or with both hands. Then, before the scene wraps up, he makes the 200 $ offer with folded arms, but listens to Agnes' reply with open arms. (00:11:35)
Continuity mistake: At the beginning of the scene when Agnes and her ex are drinking beer in the living room, Aubrey Plaza's hands awkwardly shift position in the transitions between shots as she swallows after Agnes' TikTok anecdote. (00:15:30)
