The film was mostly set during daylight hours simply as a way to cut costs; instead of having to rent all the necessary lighting equipment required to shoot at night.
Writer/director Tony D'Aquino pitched the movie as Halloween - La notte delle streghe (1978) meets Battle Royale (2000).
The film began principal photography in April 2018 as "Killer Instinct" and was planned to release by the end of 2018. A few days into the shoot; it was decided that the film would return to the original title of its screenplay: "The Furies".
This was the first and only feature-film made by The Film Distillery, a production company based in Canberra, Australia. It appears that the company went defunct following the release of the film in 2019, perhaps due to widely unforeseen financial losses as a result of the COVID-19 pandemic.
Kenneth Lampl and his then-wife Kirsten Axelholm composed the score around August 2018. Professor Lampl, whom had received a doctoral degree in composition from the Julliard School in New York, later quit his role as the head of the Australian National University's School of Music after less than two years on the job when he was accused of plagiarism by the university's staff in October 2018. The accusation was in regard to music unrelated to this film, however.
