Continuity mistake: When Alice and Mark are collecting all the sheets from the floor, Alice looks at a sheet about Amanda Krueger. Then in the next wide shot as her dad calls for her, all the sheets are in a pile to her right. Then in the following closeup, she starts picking up sheets of paper from all around her.
Continuity mistake: Right at the start of Chapter 15 on DVD:- Alice is holding a sheet "A victim of the evil within us all." Then she hands the sheet over to Mark. Then in the next shot as Mark holds the sheet Alice just handed him, you can see through it, and the title/layout of the sheet is completely different.
