The title of this movie translates as The two cats o’ nine tails… and a half in Amsterdam. As you can see, this references the names of two Argento movies, Four Flies On Grey Velvet and The Cat O’Nine Tails.

Investigative reporter Ciccio (Ciccio Ingrassia) and photographer Franco (Franco Franchi) are working in advertising when they get sent to Amsterdam to look into the murder of a diamond seller. They meet an organized crime player named Big Bon (Luigi Bonos) who is arrested as soon as their plane lands. However, he told them to find Thea (Elisabeth Sennfors), a model that he knows, who can help.

None of this has anything to do with Argento or giallo once you get past the murder mystery that sets up all of the unconnected comedy scenes and the title. Well, Luciano Pigozzi is in it as a killer, but otherwise unless you have a Letterboxd list of giallo films to add to, you can probably skip this.

Director and writer Osvaldo Civirani also made The Devil Has Seven Faces among many other films throughout his long career. The comedy duo of Franco and Ciccio also show up in another of his works, Two Sons of Trinity. Speaking of those guys, they were in several films directed by Lucio Fulci (including 002 Operazione Luna, Oh! Those Most Secret Agents!, The Two Parachutists, The Long, The Short, The Cat, How We Got into Trouble with the Army, How We Robbed the Bank of Italy and How We Stole the Atomic Bomb) and Mario Bava’s Dr. Goldfoot and the Girl Bombs.
