Demon possession, devilish cheerleaders, and Satanic rock stars are all on the chopping block with this horror comedy from the production team behind Juno. Screenwriter Diablo Cody provides the script, with producing duties handled by Jason Reitman and Dan Dubiecki. The story centers on an impish high-school student (Amanda Seyfried) who has to protect her town against her best friend, Jennifer (Megan Fox), who after being bedeviled by an evil rock band, develops a taste for human flesh. Girlfight's Karyn Kusama directs the Fox Atomic production. ~ Jeremy Wheeler, Rovi
