A lot has happened since 2003, when the first Wrong Turn was released theatrically. In 2014, the 6th part has its release and there's no real end in sight for the franchise. The 5th part Wrong Turn 5: Bloodlines directly follows the events of Wrong Turn 4: Bloody Beginnings and changes its location to a small town that was haunted by cannibals in the 18th century. But today, there's still room for some maneaters and even for "Pinhead" Doug Bradley who's character is blood-related to the three degenerated cannibals. Together, they start to hunt down anyone who comes their way. And even though the violence is still gnarly and explicit, the 5th part dials back the gore level in comparison to the gruesome 3rd and 4th installments. But that doesn't hinder the producing studio to put out 2 versions of the film as it is a tradition of the series. Apart from the Unrated, there's also an MPAA-approved "R" version (for strong bloody horror violence, sexuality, language and drug content). The nature of the changes is typical for the US. Nudity (read: nipples) and some of the more extreme gore moments had to be removed. Fortunately, it's not so easy to find the "R" version and the predominant release will remain to be the Unrated Cut.
