We think it’s rad whenever fans dig deep into horror movies with their own documentaries, and up next, film critic Calum Waddell is diving into the controversial infamy of Ruggero Deodato’s classic cannibal flick with Searching for Cannibal Holocaust, an upcoming documentary that’s been previewed this week by Rue Morgue.

“Basically, it is the story of how Cannibal Holocaust has impacted upon the lives of a number of people, including myself,” Waddell told Rue Morgue, while also sharing the trailer.

For the doc, Waddell interviewed stars from the 1980 Italian horror film and even took a trip to the filming locations in the Amazon.
