It took long enough, but 20th Century Fox has finally debuted a trailer for the Diablo Cody written horror-comedy "Jennifer's Body."

Already a career comeback for the much maligned "Aeon Flux" director Karyn Kusama, the film centers on the hottest cheerleader in high school (Megan Fox of course) who becomes possessed by a demon and starts killing all the boys in town by, um, eating them.  It's up to her dorky best friend (Amanda Seyfried) to take her down.

Check out the red-band trailer which debuted exclusively on Shock Till You Drop (with a special message from the filmmakers) and is embedded in the page below.  Then take our poll or share your thoughts on Fox's latest role in our comments section below.

Update: Looks like Shock is having some issues with their embed, but you can watch entire trailer here.
