The release history of Naked Killer, the probably most famous of the Cat III movies, is more or less comparable to the one of Jet Li's Black Mask, which is also very confusing. There are many astonishing parallels: Naked Killer was also pre-censored in HK, there are different export versions, exclusive plot scenes and no single version featuring all of the known footage. This comparison and a line of related ones aims to make things more clear, in order to possibly close the chapter Naked Killer in that aspect, although most of the contained information will be aimed at hardcore HK fans with a general interest in the version history of the movie.
