This one features the always talented edwige finch in a true giallo from 1970. It's got all the best hallmarks of that genre too, unseen killers , beautiful women and determined people trying to stop the killer. This one however is perhaps a little more classy plotwise than some giallos but it's still one of the more popular giallos out there. ON dvd this looks great and this surely could do with a blu ray release. Shameless alwsys delivers , just like blu underground with fine prints and good dvd's. their american counterpart No shame also did a great job , but they went out of business years ago. Still we have this fine company keeping these giallo/horror movies alive on dvd for us. Now where's that blu ray!. This is a italian movie with subtitles or a english dubbed soundtrack.
