It might be hard to believe, but it's been a whopping seven years since Eli Roth's last feature-length effort, "Hostel: Part II." He's finally back in theaters this September with another horror project, "The Green Inferno," and if the just-released trailer is anything to go by, he hasn't lost his passion to shock audiences.

Shot in Peru and Chile, co-written by Roth and Guillermo Amoedo, follows a group of New York City students traveling to Peru with means to stage a protest only to end up in the hands of a tribe of cannibals.

"The Green Inferno" opens on September 5th. Watch below.
