Fernando Di Leo, The Italian Connection (1972)
Yes, this is best known for the interracial hit man team that inspired Tarantino. But Di Leo has lefty cred: working with the Rome Experimental Film Center, writing a series of anti-capitalist spaghetti westerns (including some of Sergio Leone’s fists-in-the-air fistfuls), and his very class-conscious crime pulps of the early 70s. In the best sequence he ever shot (in our humble opinion), Mario Adorf has a fast-evolving relationship with a cat even in the midst of a shootout with Henry Silva and Woody Strode. Probably an allegory of something here. Something radical.
