Cannibal Holocaust
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.
