Continuity mistake: A group of people are in the copying room taking turns taking pictures of their butts on the copier. When one of them sits on the glass part of the copier, the glass part breaks. When he gets up, it's not broken.

Continuity mistake: Lucia's hair goes from disheveled to styled during the time it takes for Pia to say (over the phone), "You've gone almost a decade without a single, serious relationship, Lucia."

Plot hole: Billy's not tall enough to impale Linnea Quigley on deer antlers.
Suggested correction: The movie blatantly shows Billy lifting her high enough above his head to impale her. It's literally right there in the scene. Additionally Linnea Quigley talks about the making of the scene in the documentary "In Search of Darkness Part II," and talks about the actor living her high above his head over and over while making the scene.
Continuity mistake: After spotting her dream house Susan runs to the door. As she approaches the house it's not the same building she spotted from the car. (01:23:50)
