Directed by Sergio Leone in 1971, the film takes place during the Mexican Revolution in 1913. Juan Miranda, a Mexican bandit, has a chance encounter with early Irish nationalist John Mallory. Mallory also happens to be a demolitions expert with enough explosives to level a mountain. Sergio Leone's final western epic, it's also undoubtedly his most overlooked film. The movie has been released under many titles; Duck, You Sucker! which in turn was derived from the films Italian name Giu La Testa literally meaning "Down with the Head" and during a re-release was renamed A Fistful Of Dynamite.
