‘Body’ conscious

When acid-tongued bombshell Jennifer is possessed by a demon, it’s the male classmates that ogle her who really pay—them, and the idiot band guys who attempted to sacrifice her in exchange for hit records. Screenwriter Diablo Cody follows her massively successful hit Juno with Jennifer’s Body, a throwback 1980s-style comedy thriller staring Megan Fox as the killer cheerleader and Mamma Mia’s Amanda Seyfried as Jennifer’s nerdy friend who must stop her bloody rampage. Adam Brody, Amy Sedaris and J.K. Simmons co-star. Rated R.
