Sidney Lumet (Director), Al Pacino (Actor), John Cazale (Actor)

Dog Day Afternoon is a 1975 American biographical neo-noir crime drama film directed by Sidney Lumet, written by Frank Pierson, and produced by Martin Bregman and Martin Elfand. Starring Al Pacino, John Cazale, James Broderick, and Charles Durning, it chronicles the events following a bank robbery committed by Sonny Wortzik (Pacino) and Salvatore Naturile (Cazale).

Inspired by a 1972 Life magazine article "The Boys in the Bank" by P. F. Kluge, Dog Day Afternoon is largely a dramatization of the 1972 bank robbery masterminded by John Wojtowicz. Despite this, Wojtowicz claimed a number of the film's events contained inaccuracies. Dog Day Afternoon is notable for its anti-establishment tone, and marks the third collaboration between Pacino and Cazale, after The Godfather and The Godfather Part II. It is the final film released in Cazale's lifetime (The Deer Hunter was released after his death), and its title refers to the sultry "dog days" of summer.
