There are actually two versions of this film. Originally released in 1965, DAY OF THE NIGHTMARE was a pretty standard detective thriller with a lurid twist: the killer was an artist with a split personality (dissociative disorder) that was female. Apparently this version didn't register at the box office, because four years later it was re-released with newly-filmed sex scenes inserted--the producers lured several of the actors back to make them. This sexploitation version is the one that Something Weird released back in the 90s. I used to get their catalogues, and the writer who described this version wondered why star John Ireland was in a "nudie". The fact is, he wasn't, at least as the movie was originally released.
The 1969 recut version --the Something Weird version I originally reviewed--is available for sale on Amazon and through other second-hand dealers. The original 1965 version is on Amazon Prime. If you don't have the stomach for sixties grindhouse fare, go with that version. If you want a walk on the wild side-lesbian make out sessions, fetishistic whippings, etc.--go with the Something Weird version.
