I made a mistake. CURSE OF THE BLOOD MOON is actually CURSE OF THE DEVIL'S MOON, a film I saw theatrically almost thirty years ago but have found not one reference to in source books, on IMDB or anything. I've mentioned it a few times in fanzines and have even reviewed it but that's about as much acknowledgement as it's had. Probably an aka-but of what?
I've contacted a source about the Curse of the Blood Moon/Devil's Moon flick. Hopefully they'll be able to help out with that one. As for Witch Attack, it doesn't ring any bells. I'll do some digging and see if I can find anything.
