Comedy horror penned by Diablo Cody, writer of the 2007 hit film 'Juno'. Megan Fox stars as cheerleader captain and undisputed high school hottie Jennifer Check, who goes from being 'high school evil' (gorgeous, popular and, like, so whatever) to really evil as she morphs into a vampire killer with an insatiable appetite for male flesh. Amanda Seyfried and Adam Brody co-star.
