When Diane is nursing Roger's cut from the tree branch, he whines about it hurting. Diane goes to blow air towards the left of Roger's forehead but in the next frame her head is faced toward the right where the cut appears.
When Diane hails a cab to take Amanda to her initial interview to the Butkis', the cab changes from a Ford LTD Crown Victoria to a Chevrolet Caprice, and then back into an LTD Crown Victoria between shots.
When Alyssa and Amanda write notes to Roger and Diane in an attempt to get them to meet up in the woods, they each tell them to be there at a different time. One letter says to meet at 6:30 and the other says 7:00.
When Amanda and Alyssa meet in the woods, Amanda makes a comment to Alyssa about the "scary blonde lady" at her house. However, when Amanda saw Clarice (the scary blonde lady), she had a towel on her head, making it difficult to see her hair color.
Amanda's facial expression changes between shots of her progress up the stairs of the Callaway House: as she climbs the stairs, she is looking mildly amazed by all of the mansion's finery, but then as she starts ambling along the balcony, she merely has a bemused smirk on her face, and then a moment later she is gawking in open-mouthed astonishment again, even before she sees the life-size painting of Alyssa and realizes that it looks just like her.
Amanda could not have known that Clarice had blonde hair, since the entire top of Clarice's head was covered with a towel; besides, Alyssa had been so scared by Clarice's ghastly-pale "Old Lady Callaway's ghost" appearance (her mud-pack-smeared face) and unnerving manner (abruptly pausing in mid-stride to strike a haughtily-exasperated pose and peer contemptuously at Amanda) that she would not have even noticed what color the woman's hair was... she just wanted to get the heck outta there a.s.a.p..
Roger is talking to Alyssa and says to her, "You know we have not been able to come to this house since mom passed away." Alyssa acknowledges what he says as if she remembers this. Later on Roger tells Diane that Alyssa's mother died giving birth to Alyssa, so how could Alyssa remember this?
