Played By: Neve Campbell/Denise Richards
Movie: Wild Things (1998)

What's deadlier than one conniving, jailbait high school student? How about two of them, working together, swimming together, and bedding/scheming with an idiot guidance counselor (Matt Dillon) who makes the fatal mistake of thinking he can outsmart two teenage girls? He might actually be better off dead than having to live out his days with an astronomically shameful fail like this hanging over his head.
