Henry Silva again appears in this, the final part of the Mileau Trilogy (along with The Italian Connection and Caliber 9). Three great films by Fernando Di Leo.
While this is the weakest of the three, it is the one closest to my heart as my family comes from Palermo and Camporeale in Sicily. It's a mafia war, and has a heavy influence from The Godfather.
In fact, the top Godfather in this film is Richard Conte, Don Barzini from The Godfather, Antonia Santilli plays Don D'Aniello's daughter, who is kidnapped in the battle. She is a wild child that bonds instantly with the kidnappers.
The one thing I cannot figure from the translation is how Italian police talk about "wankers." Did a Brit do the translation?
