Seyfried in 'Body' cast


Amanda Seyfried will star opposite Megan Fox in "Jennifer's Body," Diablo Cody and Jason Reitman's follow-up collaboration to "Juno."

Karyn Kusama is directing the dark comedy-horror for Fox Atomic.

Cody's script centers on Jennifer (Fox), a cheerleader who is possessed by a demon and starts feeding off the boys in a Minnesota farming town. Her bookish best friend Needy (Seyfried) must take drastic measures to protect their town from the seductive teenager and her appetite for high school guys.

Reitman and his Hard C partner, Dan Dubiecki, as well as Mason Novick, are producing.

A March start date in Vancouver is planned.

Seyfried's star has been on the rise since she snagged the lead role opposite Meryl Streep in "Mamma Mia!" Universal and Playtone's adaptation of the ABBA musical. She also has appeared in the films "Mean Girls" and "Alpha Dog" and is a regular on HBO's "Big Love."

Seyfried is repped by Innovative Artists.
