Duck, You Sucker! (1971)

Duck, You Sucker! (1971) stands as Sergio Leone's final Western, pairing Rod Steiger's Mexican bandit with James Coburn's IRA explosives expert during the Mexican Revolution for a narrative that redefines genre boundaries. Its depiction of revolution as something that happens to ordinary people rather than heroes gives it moral complexity that is unique in the genre, backed by Ennio Morricone's elegiac score that sold 500,000 copies globally.
