: The film was shot simultaneously with another nunsploitation title, The True Story of the Nun of Monza (1980), using the same location and cast. Mattei reportedly filmed on the upper floors while Fragasso worked on the lower floors.
: The film features a soundtrack by the Italian progressive rock band Goblin . However, this was not an original score; the music was repurposed from previous works, such as Beyond the Darkness (1979), because the band's fee for new material was too high for the production budget.

While the nuns believe the killings are the work of Satan, Valerio initially suspects a human psychopath. Film Review: The Other Hell (1981) | HNN - Horrornews.net
