Continuity mistake: After Candy is told about the internet video, Fred puts her blindfold back on. Her hair, which was hanging down in her face, is now pressed tightly against her eyes under the blindfold. The camera angle then changes and now we see a close up of Candy and her face (with the blindfold still on) is instantly hair free, brushed back neatly behind her ears instead.
Continuity mistake: As Candy tries to escape Brad, she gets in the van and tries to run him down. In a wide shot we see the van coming towards Brad but it is obviously not in line to hit him. But just then, the camera cuts to a close up and Brad gets hit squarely by the van head on.
