This is actually only Roth's fourth effort as a director, following Cabin Fever and the two Hostel movies. But he's built a heavy rep working on projects like Grindhouse and the Netflix series Hemlock Grove. It's apparently given him the license to call himself a “Horror Master” as he does in the trailer, which is totally different from being a “Master Of Horror.”
But what does all this mean for Roth's Green Inferno? Chiefly that the plot will center on a group of "naïve do-gooders" who survive a terrible plane crash in the midst of the Peruvian jungle only to be the prey of a batch of man-eating tribesmen. So basically, it'll fit well with Roth's established xenophobic horror themes.
The Green Inferno will be the first movie Roth has helmed since 2007's Hostel: Part II, and horror fans are sure to cheer his return to the director's chair. Unfortunately, Worldview won't even reveal the logline behind the curious title at this time, but with the story being born from Roth's twisted imagination, there's bound to be plenty of gore in store.
