It can strongly be argued that the 1970s was the decade when Hollywood fully did-away with traditional movie-making conventions. Once-radical films of the 60s, such as Easy Rider, Bonnie and Clyde, Rosemary’s Baby and The Wild Bunch, paved the way for a new generation of writers, producers and directors to creatively flourish, no longer bound by long-held genre conventions.
fiction tales became more pessimistic and westerns became more
realistically violent. Even the few epics being made at the time, such
as The Godfather, were ultimately tragic and extraordinarily dark. With
the Vietnam War coming to an agonizing end and Watergate instilling an
overall distrust in authority, Hollywood knew well-enough to capitalize
on the public’s newly found cynicism with a plethora of thrillers which
made Hitchcock look like Walt Disney.
