The band's video for the song "Cannibal Holocaust" is included as a bonus feature in the Grindhouse Productions re-release of the Italian film.

It is known that Killjoy produced a demo from the Ohio band Arch Rival, but it is unknown if he was actually a member of the band or not.

Back in 1999, Killjoy, Fenriz (Darkthrone), Satyr (Satyricon), Phil Anselmo (Pantera), and Maniac (Mayhem) started a "supergroup" called Eibon. They were supposed to record a full-length, but due to their heavy schedule, plans were changed. Maniac left the band, and they released one track called "Mirror Soul Jesus" in Moonfog's 2000 compilation A Different Perspective. They also recorded an unnamed song.

Fug and Frediablo are brothers.

The band broke up in 1987 and remained inactive for more than 10 years; until 1998 when Phil Anselmo (Pantera) approached Killjoy with some riffs, he subsequently joined the band on guitar and wrote all the songs for the album Holocausto De La Morte.

Formed in 1984, Necrophagia were one of the very first death metal bands; they focused on gore and horror movies since the beginning and are also credited as pioneers of the "Horror Metal" subgenre. Killjoy is the leader of the band and the only original member.

Necrophagia's 2003 album The Divine Art Of Torture is full of references to the movie "The Coffin Joe" (Zé do Caixão), including the cover artwork which depicts Coffin Joe himself. Just like other Necrophagia albums, the album bears many horror movie references.

The intro of "Blaspheme the Blood" is taken from The Exorcist III. "Zé do Caixão" refers to the aforementioned "Coffin Joe" movie". Also "Divine Art Of Torture" features a sample taken from that movie, where Coffin Joe defies christian God. At the end of "Rue Morgue Discipline", vocalist Killjoy shouts out names of different horror/gore film directors, while the song title is a reference to the movie Murders in the Rue Morgue.
