No, not the Boss from Jersey, il Boss from Palermo!
I recently got a four-pack of Fernando Di Leo’s Poliziotteschi (in Blu-ray no less) and I watched the 1973 film Il Boss (or The Boss) starring Henry Silva. It was crazy. The opening scene, which also is the first scene in the trailer below, features De Silva’s character shooting a grenade launcher into a movie theater to kill a crime boss. It seems to be at least partial inspiration for Tarantino’s movie theater holocaust in Inglorious Basterds. Great stuff, if you are looking for grade A Italian b-cinema, this comes highly recommended.
Synopsis of the film from Rarovideo:
Based largely on real people and actual events, Fernando Di Leo’s action-packed film – the final part of his Milieu Trilogy – is his boldest commentary on corruption and the criminal underworld. A bomb attack in a cinema in Palermo kills all the members of one mafia family except for Cocchi. Realizing that the instigator of the bomb attack is Daniello from another mafia family, Cocchi is determined to revenge. Lanzetta, a hired killer employed by Daniello is told to assassinate the rival family. Following Lanzetta’s successful hit he finds himself in the midst of the ensuing gangland war, with Daniello attempting to turn him into the police, his boss’ daughter kidnapped, and the rival gang looking for revenge.
