Trivia

The film had a troubled production. When director William Lustig's rough cut came in at only 51 minutes, he refused to shoot the additional scenes the producers as well as the film's distributor, Overseas FilmGroup, wanted and quit the project. The balance of the picture was directed by co-producer Joel Soisson. Prior to Blue Underground's DVD and Blu-ray release of the movie in 2013, Lustig was the film's credited director, but the Blue Underground version is credited to the Director's Guild of America pseudonym Alan Smithee.

Expert editor Michael Eliot was brought in to re-edit the movie because of the behind the scenes problems and short running time of William Lustig's rough cut. This is why there are several scenes in the movie which are very obviously outtakes of scenes from Maniac Cop 2 (1990).

As with the preceding film, Matt Cordell (Robert Z'Dar) speaks only once, this time telling Julius Harris to finish a voodoo rite.

The church exteriors are of the same church used in John Carpenter's Prince of Darkness (1987).

Ted Raimi plays the role of a news reporter. In the previous two Maniac Cop films this role was played by his older brother Sam Raimi.
