<P> Cannibal Holocaust has been regarded as the apex of the cannibal genre, and it bears similarities to subsequent cannibal films made during the same time period . Cannibal Ferox also stars Kerman and Pirkanen, and star Giovanni Lombardo Radice says it was made based on the success of Cannibal Holocaust . Cannibal Ferox has also been noted as containing similar themes to Cannibal Holocaust, such as comparison of Western violence to perceived uncivilized cultures and anti-imperialism . In a mixed review, film journalist Jay Slater claims, "Certainly a tough customer, Cannibal Ferox still fails where Deodato succeeds . (...) Lenzi attempts to tackle cultural defilement and racial issues, but Cannibal Ferox is nothing more than a shoddy exercise in sadism and animal cruelty ." Reviewer Andrew Parkinson also notes, "At the end, there is a basic attempt to validate Cannibal Ferox, posing that old chestnut of whether civilised man is actually more savage than the uncivilised tribespeople ." </P> <P> Unofficial sequels to Cannibal Holocaust were produced in the years following its release . The titles of these films were changed following their original theatrical releases in order to associate the film with Cannibal Holocaust in different markets . In 1985, Mario Gariazzo directed Schiave bianche: violenza in Amazzonia, which was also released as Cannibal Holocaust 2: The Catherine Miles Story . In addition to the new title, Slater notes similarities between the score in The Catherine Miles Story and Riz Ortolani's score in Cannibal Holocaust . Previously known for his work in Mondo films, Antonio Climati directed Natura contro in 1988, which was released as Cannibal Holocaust II in the United Kingdom . </P> <P> In 2005, Deodato announced that he planned to make a companion piece to Cannibal Holocaust entitled Cannibals . Deodato was originally hesitant about directing his new film, as he thought that he would make it too violent for American audiences . However, while he was in Prague filming his cameo appearance in Hostel: Part II for Eli Roth, Deodato viewed Hostel and decided that he would direct after all, citing it as a similarly violent film that was given a mainstream release in America . Although the screenplay, written by Christine Conradt, was completed, a financial conflict between Deodato and the film's producer led to the project's cancellation . In 2013, Roth directed The Green Inferno, which takes its title from the fictional documentary produced in Cannibal Holocaust . Roth's film was intended as an homage to Cannibal Holocaust and other cannibal films from the same era . </P> <P> The film's influence has extended to other media as well . In 2001, Death metal band Necrophagia released a song entitled "Cannibal Holocaust" from the eponymous record . British Author Saurav Dutt also published Cannibal Metropolis, a novel inspired by Cannibal Holocaust set in an urban location . Like Cannibal Holocaust, the novelization features explicit scenes of violence, horror, and rape . </P>
