Antonio Climati and Mario Morra took footage from their two previous documentaries, Savage Man Savage Beast (1975) and Savana violenta (1976), and incorporated it into this movie.
This film had a confusing history with the Australian censors (OFLC). It was originally passed uncut (93 minutes) with an R18+ rating, but a video release (PAL running time of 81 minutes) was refused classification due to excessive violence. Other, various prints would receive R18+ and M ratings, but the only time it would ever be released in Australia was with an R18+ rating for an 87 minutes cut (PAL format running time).
The scene featuring an execution by having a man's arm torn off by two trucks is actually a fabricated sequence.
