Hmm, upon reading those last two comments and after digging out the box of reels and looking at them, I am less certain than what I have now is an incomplete cut of ANH and perhaps a wacky B-grade horror flick instead. Most of the reels are marked "Evil Night", and since there were several reels of Steve Barkett's THE AFTERMATH, this may very well be his other film EMPIRE OF THE DARK (which has to do with a satanic cult, aliens, and...ninjas!?) under an alias. And since the fellow who used to live in the apartment these came from had told me he was a friend of Barkett's, it starts to make a little sense.
Could it be possible that someone used filler from ANH as leaders for these reels? It certainly seems possible.
Call me a cretin, but now I'm even more curious as to what this is!
