Italian organized crime

His The Godfather trilogy remains the most iconic and deeply nuanced exploration of Italian-American organized crime, examining family dynamics, power, and moral corruption across generations.

Though known for westerns, Leone's Once Upon a Time in America provides a masterful, operatic meditation on organized crime, friendship, and the American dream through an Italian-American lens.

His films Goodfellas, Casino, and The Irishman offer visceral, character-driven examinations of Italian-American mafia life that blend historical accuracy with psychological depth and moral ambiguity.
