The 'New Hollywood' and Post-classical cinema
'Post-classical cinema' is a term used to describe the changing methods of storytelling in the New Hollywood. It has been argued that new approaches to drama and characterization played upon audience expectations acquired in the classical period: chronology may be scrambled, storylines may feature "twist endings", and lines between the antagonist and protagonist may be blurred. The roots of post-classical storytelling may be seen in film noir, in Rebel Without a Cause (1955), and in Hitchcock's storyline-shattering Psycho.
'New Hollywood' is a term used to describe the emergence of a new generation of film school-trained directors who had absorbed the techniques developed in Europe in the 1960. Filmmakers like Francis Ford Coppola, George Lucas, Brian de Palma, Martin Scorsese, William Friedkin and Steven Spielberg came to produce fare that paid homage to the history of film, and developed upon existing genres and techniques. In the early 1970s, their films were often both critically acclaimed and commercially successful. While the early New Hollywood films like Bonnie and Clyde and Easy Rider had been relatively low-budget affairs with amoral heroes and increased sexuality and violence, the enormous success enjoyed by Coppola, Spielberg and Lucas with The Godfather, Jaws, and Star Wars, respectively helped to give rise to the modern "blockbuster", and induced studios to focus ever more heavily on trying to produce enormous hits.
