Continuity mistake: In the opening scene, from the moment the little boy wipes the blood on his face to the last time we see him (when the mom is crying about how "It got our dog!"), the amount of blood on his face changes at least twice. Sometimes there is more or less depending on the shot.
Continuity mistake: In the scene where Jason has hold of the little boy in the Halloween costume, the hat on the boy's head disappears between shots, just before Jason releases him.
Continuity mistake: When Ginger and Brigitte are buying tampons, when Brigitte says "This one comes with a free calendar" she turns around to look at Ginger. The way she is holding the box of tampons and her laptop (I think that's a laptop?) changes instantly between cuts. Ginger also moves about a foot or two back between the same cut.
Continuity mistake: When Ginger and Pamela are talking about why Ginger's back is hurting, the bread Ginger is eating and the hand she's holding it in changes repeatedly throughout the scene.
