Former O.C. nerd-hunk Adam Brody and Juno's dad J.K. Simmons have joined the cast of Diablo Cody's horror-comedy Jennifer's Body. They round out a cast that already included Megan Fox and Amanda Seyfried. The Hollywood Reporter has more:

Cody's script centers on Jennifer (Fox), a cheerleader possessed by a demon who starts feeding off the boys in a Minnesota farming town. Her bookish best friend (Seyfried) must take drastic measures to protect the town.

Brody will play Nikolai, a hot lead singer of an up-and-coming rock band with a penchant for evil. Simmons will play Mr. Wroblewski, a high school science teacher.

Nice — I hope this means we get to watch Brody rock out onstage. I bet he'd be good at that. I'm so curious to see how Cody's follow-up project to Juno shapes up.
