The unrated version of the movie was shown in sixty theatres on its debut weekend across the United States and Canada. Most of the theaters were unaware of the extent of the extreme violence and vile content in the film, and nearly all of the theaters had stopped playing the movie by Monday morning.
The first horror movie to be theatrically released unrated in mainstream cinemas across the United States since George A. Romero's Dawn of the Dead (1978). When the MPAA kept giving this movie an NC-17 rating with each submission, the filmmakers decided to circumvent them, and go straight to a major cinema chain and show them the film. When AMC theaters saw the uncut movie, they loved it. Then, after hearing just how much of the violence would have to be cut out to get an R-rating by the ratings board, AMC agreed to release this movie in their theaters unrated. However, they later pulled the film from their theaters, when it was released for only a few days.
According to the horror website bloody-disgusting.com, this movie's final tally of fake blood used in its making, is one hundred thirty-six gallons. That's eighty-one gallons more, and more than double the amount used in the making of Hatchet (2006), which reportedly used fifty-five gallons of fake blood.
To keep details under wraps, even the crew did not receive copies of the script, and the majority of cast only received select pages. Fake scripts, fake endings, and fake storylines were circulated around the industry, and no visitors or guests were allowed near the set.
While most every store, rental, and streaming carrier carried this movie in the Director's Theatrical Unrated Cut, Red Box insisted on the distributor creating an R-rated version that has most every death scene taken out of the film. Adam Green's comment to press was that he looks at it no differently than when a film has to be edited for television or airplane rentals, and does not blame Dark Sky for censoring the film for Red Box. This movie only had ratings problems in the U.S., further supporting the filmmaker's claims that the ratings board here was being unfair.
Cameo: The character Parker O'Neil (Emma Bell) from Adam Green's movie Frozen (2010) is seen briefly on the television in Reverend Zombie's (Tony Todd's) voodoo shop speaking to news cameras about her lawsuit and settlement against the ski mountain from the film.
During the meeting, when Reverend Zombie (Tony Todd) is offering the bounty, one character mentions Jason Voorhees. He then also mentions he comes from the town of Echo Falls, and that town's urban legend is known as Leslie Vernon, a reference to Behind the Mask - The Rise of Leslie Vernon (2006).
In Canada, the film was scheduled to play in Toronto and Montreal theaters on October 1, 2010. However, because the film was not rated by the cities' provincial rating agencies, the theaters were threatened with fines if it still played, and thus, it was pulled from release. On Twitter, Adam Green referred to the occurrence as "sad".
The R-rated version of the film that Dark Sky Films created for Red Box rentals is missing close to two full minutes of gore and violence that the MPAA insisted they pull out. Adam Green was not happy about that version, but has stated that he supports Dark Sky's decision, and understands why they had to do it for that one outlet. Green has publicly stated that those who feel the film's stance on staying unrated for theaters was a "publicity stunt", should compare this R-rated version to understand just how severely the MPAA was trying to castrate the film, and change the tone of it. All other retail outlets supported Green's claims when they agreed to carry the film Unrated in their stores. They felt there was nothing that offensive about the film in the first place, and that it never should have been given an NC-17 like the MPAA tried to give it, to keep it out of mainstream theaters.
During one scene a guy mentions "Jason Voorhees" when they discuss "who is Victor Crowley?" Jason Voorhees is an another killer and mysterious bogeyman with supernatural powers performed by Kane Hodder, who plays Victor Crowley and Victor Crowley's father in this movie.
