Hopefully, I will eventually come across the answer to this question. print without roughly 10 seconds affecting the running time and with no dialogue to affect the English dubbing. However, Catherine's topless scene could have been edited from the U.S. That would lead me to believe that they are the same print. The Blue Underground DVD runs right at 112 minutes, and the press-reviewed English-dubbed prints reviewed in 1971 list a 112-minute running time. They are not particularly graphic as far as blood and gore goes, but they could certainly be considered disturbing for younger viewers. Also, there are a number of murder scenes. It is not a long scene, but it is all out there and more than just fleeting. First, Catherine does her first full-on, here-they-are, well-lit topless scene. It was not unusual to have some violence and some fleeting nudity in a 'GP' movie of the early 70's, but the cut of the film that I watched would seem to be pushing the boundaries of that rating. Am I watching the cut that received a 'GP' rating upon release in the U.S.? Keep in mind that a 'GP' rating in 1971 was somewhere between a 'PG' and a 'PG-13' rating today. I'll leave the plot summary at that, so as not to risk any spoilers.Ģ. Catherine plays the role of Anna Terzi, daughter of the institute's owner and one of many possible suspects in the case. The mystery involves research at the institute concerning genetic markers that predict individuals more likely to be murderers. Ultimately, murders begin to occur, involving individuals connected with the institute, and Franco and Carlo work together trying to solve the mystery.

Carlo Giordani (James Franciscus) is a newspaper reporter that covers a burglary at the Terzi Institure, which occurred that same night. Walking home one night, they overhear two men in a car discussing a discovery that must be reported. Franco Arno (Karl Malden) is a blind professional crossword puzzle maker who lives with his young niece. Il gatto a nove code (aka The Cat O'Nine Tails), directed by Dario Argento (often referred to as the Italian Hitchcock), is a suspense thriller involving genetic studies at a research institute.
