Factual error: After Marisa is almost raped by those 2 guys, she wants to be driven to work. Her brother drops her off, but wouldn't give her the car because he had school the next day. But it was the day before Christmas Eve that night, and who has school on Christmas Eve?
Continuity mistake: When the two guys are beating on the cigarette machine, Caroline gets him the pack he wants (after he tells her two different brands), and she has the two packs he didn't want in her hands. When she walks away, the packs are no longer in her hands.
Continuity mistake: In the beginning of the movie, Marissa is looking in the mirror and getting ready when her "date" pulls up, so she throws all her makeup into her purse. In the next shot it shows her running in front of the mirror to leave her room and the make up is back on her armoire.
