This one is so obviously trying it's best to rip off other (more successful) gialli, and in some ways it's a fun movie to watch. There's a scene where the music obviously tries oh so hard to copy Goblin, particularly during the murder scenes - in fact the build up to some of these sequences is quite (intentionally) reminiscent of Suspiria. Like Bido's The Bloodstained Shadow I think it's well worth a watch.
This was issued on video in Italy on the PAC label in a version running 88m 12s, and got a UK video release in 1995 courtesy of Redemption (in the days I was working for them) with a running time of 91m 36s. There's a US release issued by VCI under its American release title "Watch Me When I Kill" and a German version on the X-Rated label.
Does anybody know of any any versions with anything extra?
