Nina Hartley told in a 2019 interview with Adult Empire, that Ricky Greenwood storyboards his movies. According to her, it's the 3rd time in her then 35 year career in the adult industry that someone has done that.
Ricky Greenwood told in an interview, that Ken Russell, Jesús Franco, and Joe D'Amato were the creative influence for this movie, like they were for the 1st movie in the series, Confessions of a Sinful Nun (2017).
Additionally, he named Jerzy Kawalerowicz movie Mother Joan of the Angels (1961) as an influence, as both movies have a character named Mother Joan in them.
