1973 · Sidney Lumet
How Serpico has been received, argued over, and remembered.
A hit on release — Pacino's first post-Godfather lead earned him an Oscar nomination and a Golden Globe win — and it never really fell out of favour; it's since settled in as a cornerstone of gritty-70s-New-York cinema and the start of Lumet's great cop-corruption cycle.
The perennial Letterboxd fight is intra-Lumet: is Serpico the lesser warm-up to Dog Day Afternoon and Prince of the City, or the purest of the three?
The name itself became the shorthand — call any honest cop (or self-righteous snitch) 'Serpico' and everyone gets it — and Pacino's bearded, beaded undercover look basically defined the 70s cop-movie aesthetic that everything from sitcoms to SNL has riffed on since.
Firmly canon — a 'you must have seen this' entry in both the Pacino and New Hollywood syllabi, even if it's the Lumet-Pacino film people rank second.
