- Banned in China: And a whole lot of other countries. The most notable exceptions were Japan, where it was slapped with an R-18 rating, and the United States, where the only penalty for its depiction of gore was the dreaded X rating (issued by the MPAA). Eventually, a few more countries (most notably Australia) passed it uncut. As of May 2011, the UK's only problem with the film is the turtle, monkey and snake being killed onscreen (though a cut version has been released with the highest UK rating).

- Creator Backlash: Ruggero Deodato came to deeply regret making the film, and has vocally denounced the animal cruelty shown. Almost none of the other cast and crew have anything kind to say about it either.
- Deleted Scene: Ruggero Deodato wanted a scene in which the natives fed an enemy tribesman to piranhas, but he didn't have a working underwater camera. Only still shots of the scene exist.
- Hostility on the Set:
- Well since actual animals were killed, it wouldn't be surprising that behind the scenes would be a complete mess. Tensions were extremely high on set throughout filming. Robert Kerman and director Ruggero Deodata would get into long, extended fights that brought filming to a halt, and many of the cast members reported being underpaid, with principal actor Carl Gabriel Yorke threatening to walk out on the project unless he and everyone else were paid fairly. Kerman would later complain of Deodata being unfair to the natives, and refusing to compensate them for their time on the film. He also described Deodata as a "sadist" in his treatment of the cast, crew and natives.
- Another huge point of contention was the real life animal cruelty depicted. Robert Kerman reportedly stormed off the set during the coatimundi death, and actor Perry Pirkanen wept after filming the butchering of the turtle. Carl Gabriel Yorke also flat out refused to shoot a pig as part of a scene, leaving it to another actor to take his place.
- Old Shame: Ruggero Deodato has not only expressed regret for the authentic animal deaths, but he also allegedly said he wished he never made the film in the first place.
- Practical Effects: The scene in which one of the actresses appeared to be impaled from anus to throat was so shocking and realistic that it was used as evidence the movie was a real snuff film; no one, the prosecutors argued, could have faked it. The director demonstrated before the court how the effect was accomplished: a bicycle seat was mounted atop the lower half of a pole and the actress sat on it. The upper part of the pole was a short length of balsa wood held between her teeth. With her head tilted back, the pole appeared to come out of her mouth. The director claimed that the most dangerous part of the stunt was balancing his actress on the bicycle seat, which was several feet off the ground.
- Romance on the Set: Allegedly. In a 2005 interview, Carl Gabriel Yorke said that while rehearsing the sex scene with Francesca Ciardi, she suggested that they go out in the middle of the jungle and "actually do it". Yorke declined, saying he had a girlfriend back in New York. However in 2009, Ciardi stated that the sex scenes were not simulated, and that she and Yorke were lovers off-screen during filming.
- Star-Derailing Role:
- Robert Kerman was a porn actor trying to establish himself in mainstream films. After this movie, "legitimate" roles dried up, and he went back to porn.
- Surprisingly averted with Alan Yates' actor, Carl Gabriel York, who, unlike the other actors in the movie, still managed to have a career and starred in successful films, such as Jack the Bear, Idle Hands, Apollo 13, and Ghost in the Machine.
- Viral Marketing: The movie advertised itself as a true story, and the actors were contractually bound to avoid public appearances as to keep people think it was real. Remember anything? It worked too well since the director was arrested for multiple murder until he could prove that it was just a movie—which he had to void the original contracts of the actors to accomplish.
- Working Title: The Green Inferno. This was changed at the last minute to its current title as it was considered more shocking (especially with the word "holocaust"). Eli Roth would later make a cannibal themed horror film titled The Green Inferno as an intentional homage to this film.
