Eli Roth, a horror filmmaker best-known for hits like "Hostel" and "Cabin Fever" as well as for finding unique ways to almost die in real life, is finally getting his chance to show the world what happens when cannibals and rain forest activists mix. Titled "The Green Inferno," this is definitely not a dinner party we're interested in attending.

Roth, 43, was inspired to come up with the idea of "Green Inferno" based on what he viewed as "slacktivism" in the wake of viral campaigns for natural disasters and other atrocities. Sure, we all express outrage and cry out for change over Twitter and Facebook, but what would happen if we actually decided to take action? In "Green Inferno," a group of student activists, appalled at illegal clear-cutting in the Peruvian rain forest, decide to do something about it. They ultimately succeed, but since this is an Eli Roth film we're talking about, things don't go completely as planned.

"They chain themselves to trees and protest and stream it and hash-tag, and it works," Roth told IGN in 2013. "It actually shuts down the operation. Then on their way home, their plane crashes. And the very people they save are like 'Ah, food – that’s great!' It’s like a free lunch, and they are brought back into the fold of absolutely barbaric, primitive man. People that have had no contact with the outside world."

In an effort to accurately capture this remote, primitive setting, Roth said the cast and crew team ventured deeper into the Amazon rain forest than any other production before them. "I went so far up the river, we went to a village where they had no electricity, no running water, and they never before had seen a movie or television," he told Empire.

Actress Lorenza Izzo, who plays the lead in "Green Inferno," said Roth's decision to shoot in the remote village for a month was something she'll never forget.

"We were working with this village, people who have never seen ice that don’t have electricity. It was strong," she told Collider. "We were isolated from everything, no cellphone, no Internet, no nothing. So I feel like we all came back with a different mentality and I think that’s what acting is about. You have these learning experiences that change you a little, and 'Green Inferno' really did that for us. Plus all the bugs, plus the boat rides. It was so beautiful."

Despite it's completion in 2014, "Green Inferno" languished in release limbo due to financial difficulties with production company Worldview Entertainment (the same company that derailed Adrian Grenier's "Loneliest Whale" doc last year). Thankfully, Blumhouse Tilt, Universal Pictures and High Top Releasing have all banded together to give Roth's latest a proper debut on Sept. 25 in more than 1,000 theaters. Needless to say, the director was thrilled.
