I've just bought the R1 Gorgon 1-4 set for £25, to my knowledge they're less cut than the R2 equivalents and contain 2 bonus episodes.
I think I already have part 3 in a VHS bootleg. It included Bigfoot footage, people eating a placenta and dogs eating a man alive etc. Is this the one? My VHS copy is under the title 'FEAR'.
Thanks for the heads up about Killing of America. I'll check that out. Just working me way through the Blue Underground Mondo Cane set and it's really piqued my interest in Mondos.
Embrace this moment. Remember, we are eternal, all this pain is an illusion.
