SYNOPSIS:
A young American witnesses a murder while visiting Rome and inadvertently stumbles upon a serial killer nicknamed the ABC murderer – and her name begins with a D!
Part of the considerable charm of this discerning Blu-ray release is that it shows exactly how two different releases of the same film can offer remarkably diverse experiences…
Bava’s original Italian release with the Hitchcockian inspired title takes in a far darker sense of impending dread and horror. After all, as the excellent extra features from various genre experts inform us, this title can in many senses be seen to be one of the first true giallo films, mixing elements of murder mystery with the modish cinematography and stylistic elements that would go on to inspire the next generation of blood-red drenched dream weavers.
