So far Megan Fox has played mostly damsel-in-distress type roles, but all that is about to change when she becomes a demon and eats boys at the local high-school in Jennifer’s Body.

A couple of new grainy pictures from the film have popped up online courtesy of Empire and Film School Rejects. They show Fox and her co-star Amanda Seyfried in bloody dresses, looking quite disturbing.

Written by Diablo Cody, the film follows Fox, a mean cheerleader-type, possessed by a demon who starts eating boys at the school. She is to be saved by her best friend (played by Seyfried) who must first escape a correctional facility and go after Nikolai (Adam Brody) and his Satan-worshipping band who are responsible for the demonic transformation.

The film is set for release this Septemer.
