The movie was never completed.
The production company went bankrupt and production was shut down on the first day of shooting. A tad under 34 minutes of raw footage exist that was published on a bonus disc of a DVD box set. This raw footage is not like 30 minutes of a film, but really raw footage including multiple takes. In 2012 a feature length version was cut that consists mostly of archive material from the first three movies plus the few scenes from the raw footage.
