This title confused me because the opening sequence, and throughout the film, we are advised there were only five murders. Who were the other two?

And are we to believe that David returned from the dead, became a Hollywood actor, got himself cast in a movie at the same house he was murdered at (as procured by him) to only then recite chants to bring back another dead relative to kill off the same movie crew?

The movie was enjoyable for silly, B-grade, drive-in theater fare, but it really didn't make a lick of sense. And it felt like it was bordering on hagsploitation (except with a man) by having has-been John Ireland lead.
