This made them angry since the film was on an amazingly short 10-day shooting schedule.
Director Dave Parker refused to include nudity.
Dave Parker wrote the role of Eibon with Tom Savini, Alice Cooper, Blackie Lawless, and Dee Snider in mind as possible actors for the role.
The hospital set at the beginning of the film is re-used from End of Days.
Producer Charles Band has since gone on to say he didn't care for this film.
