George Lucas
Arguably the most important film innovator in the history of the medium, George Lucas continually "pushed the envelope" of filmmaking technology since his early days as a student at U.S.C. Considered a wunderkind by his contemporaries, he had a much harder time communicating his vision to studio executives, whose meddling managed to compromise each of his first three feature directing efforts in some way. The monumental success of "Star Wars" (1977) ushered in the era of the "summer blockbuster," which, despite the later popularity of low budget independent films, was still the prevailing mentality powering the Hollywood engine. Though he set the tone and established the expectations which influenced studios to devote the bulk of their resources to films designed to blast off into hyperspace for spectacular profits, it was doubtful that a film as revolutionary as "Star Wars" was in its day could get made in the later blockbuster assembly line climate of the new millennium.
