Her work on this film inspired Penelope Spheeris to become a foster parent.
This film was not released on DVD/Blu-Ray until June 2015. The director stated that she could not release the film previously without giving up the rights to the first two movies, which she elected not to do.
The "Cop Doll" seen in the messy, hoarded house in the film is actually a "Wrestling Buddies" doll of WWF/WWE wrestler Big Boss Man.
The film was originally to be titled 'The Decline In Eastern Civilization' and was to cover the Japanese heavy metal music scene.
Part 3 is director Spheeris' favorite installment of all three parts because she feels the issue of homelessness is more relevant than ever.
