A brand new “On-Set” featurette for Jennifer’s Body has been released by 20th Century Fox. The video gives us a little bit of a better look at the Diablo Cody (Juno) penned movie and what it’s about, as well as brief clips of director Karyn Kusama (Æon Flux, Girlfight) and stars Megan Fox (Transformers, Jonah Hex) and Amanda Seyfried (Mean Girls, Alpha Dog) talking about their parts in the project.

The story follows a popular high school cheerleader (Fox) who becomes possessed with a demon after an attempt to use her as a sacrifice goes awry. After the demon takes over her body, she begins to seduce the boys of her high school (with ease), and when they’re close enough, she feeds on them. Her best friend since childhood (Seyfried) happens to be more on the nerdy side of the clique fence, and finds herself in a position where she needs to stop Jennifer’s carnage-ridden path of death and devouring.
