Bloodsucking Pharaohs in Pittsburgh (1991)
Blu-ray ALL Germany - DigiDreams Studios
(presumably both releases)
runtime: 89:07
(In other words, the addtional shots in the unrated version only amount to about 8 seconds, compared with the R-rated version.
I can confirm that these additional shots are from a poor quality source, although they are still widescreen).
source: I own this Blu-ray disc as a bonus disc in the Nightmares in a Damaged Brain Blu-ray German mediabook from Astro Records & Filmworks
(note: this release of Nightmares in a Damaged Brain is not yet in the database)
