I don't know if Sergio and Sam were friends or if even they met each other but there were some coincidences between those two great Directors:Sam realized some westerns in a different tone, when western movies were out of fashion.Sergio tooSam realized a " Mexican Civil War " western "The Wild Bunch " and Sergio too (DYS)Sam Realized gangster movies Sergio too Sam realized a Second World War Movie " Iron Cross" and Sergio projected another one "Leningrad".Like great artists they shared influences and vision .Both were great fans of Ford.Both died too early (Sam at 59) due to heart disease .Both suffered because their films were cutted by distributors or producers ( Dundee, OUATIA)
HiI don't know but my guess is that these two men werenever in the same part of the world working wise.
However I think that Sergio well knew Sam Peckinpah work and was a fan ("the wild bunch" in My name is..."
Never really been a fan of The Wild Bunch, found Straw Dogs to be much more meaningful.
Sure deMaie, but Sergio began to work in USA for OUTIW and met some people: Carpenter, Millius... I 'm wondering if "the profession" was not a little bit snob with him except Clint, Eli ( who convinced Henry), Lee..
