Starring: Mary Elizabeth Winstead, Michelle Trachtenberg, Lacey Chabert, Katie Cassidy
Continuity mistake: At the end, while Billy chases Kelli, Kelli knocks over a cart of surgery supplies, spilling the material forward. However, a few shots later, Billy is shown picking a scalpel up from the small tin pale, which slid ahead of Kelli. So how could Billy have picked up the scalpel if he was behind Kelli?
Dana Mathis: Are you high? It's freezing out there.
Trivia: The sorority mom, Andrea Martin, is also one of the girls in the original "Black Christmas". Her name in the original was Phyllis.
Question: Why would Agnes join Billy in his killing spree? She was a victim of him, losing an eye and her parents. She could've joined the sorority girls in stopping him.
Answer: Maybe like him she's also mentally ill, getting it from their mother. Maybe she feels doing this will bring them together.
Answer: Because Agnes is in love with her fatherbrother, and besides, they were invading her home, from her perspective.
