Duck, You Sucker!
The development of "Duck, You Sucker!" began during the production of "Once Upon a Time in the West", when Sergio Leone's collaborator Sergio Donati presented him with an early treatment of the film. Around the same time, political riots had broken out in Paris, and the ideals of revolution and left-wing nationalism had become popular among university students and filmmakers across Europe. Leone, who had used his previous films to deconstruct the romanticization of the American Old West, decided to use "Duck, You Sucker!" to deconstruct the romanticized nature of revolution, and to shed light on the political instability of contemporary Italy.
