Just discoverd on Netflix...never found on DVD!.

All I found on the film is "Killer's Moon", a similarly obscure British slasher from 1977 that gained infamy from apparently being labeled a “Video Nasty” at one time or another, a fact that kept it both underseen and very sought out among enthusiasts.

For obvious reasons, "Killer's Moon" feels very European with its soft focus photography and the slight gothic flavoring. Whereas American films like this really tended towards being super grimy and gritty, their European counterparts mostly had some sense of flair and style.
