The Case of the Bloody Iris is definitely not a masterpiece but it's fun.
Guliani Carnimeo acts here as a replacement for Sergio Martino. The movie was produced by his brother Luciano Martino and features the same team that worked on
All the Colors of the Dark. Same composer (Bruno Nicola?), same writer (Ernesto Gastaldi), same lead actors (Edwige Fenech and George Hilton), same editor (Eugenio Alabiso),...
I always wondered if Sergio Martino did not direct a few sequences...
Anyway, I like
Bloody Iris. It fits perfectly in a "Shameless" collection
