During the post-production of The Dead Next Door in 1989, producer David DeCoteau offered J. R. Bookwalter a $15,000 budget to write and direct a film with the title Robot Ninja.

[3] In 2014, Felix Vasquez Jr. of Cinema Crazed wrote "As noted, most of the narrative is all over the place, with the movie showing its bottom of the barrel budget.

Thompson of Rue Morgue gave the film a positive review, writing, "A cult film in the truest sense, Robot Ninja has been out-of-print since its initial run from Cinema Home Video, making it something of a rare gem to VHS aficionados, who helped keep its memory on life support despite its myriad presentational flaws."

Thompson continues, "Robot Ninja is the real deal: a charmingly lowbrow cult actioner that sits perfectly in that delicious liminal space between postmodernism and excessive 80's earnestness that all those turbo kids and hobos with shotguns are trying so hard to emulate.
