Stock footage from the film Nuova Guinea, l'isola dei cannibali (1974) was used for the native scenes.

Some of the animals featured in the stock footage aren't indigenous to New Guinea.

Vestron Home Video's release, around 1985, of the picture, under the title Night Of The Zombies, was the same print used by Creature Features for home video tape in 1996. Creature Features added a brief card to the tail end of the closing credits for its copyright. This exact same print, even including the Creature Features copyright card, was used by Cydonia Pictures for its Night Of The Zombies DVD release in 2002. The same year, Anchor Bay Entertainment, released a cleaned up DVD under the title Hell Of The Living Dead. All of these Night Of The Zombies versions are identical, save for the inserted Creature Features copyright card. The film print is the infamous one known for being too dark, due to numerous copies being made, and, thus nearly impossible to tell a lot of what is going on in the film.
