David Wark Griffith was an American director, writer, and producer who pioneered modern cinematic techniques. He is most remembered for The Birth of a Nation (1915) and Intolerance (1916). The Birth of a Nation made use of advanced camera and narrative techniques, and its popularity set the stage for the dominance of the feature-length film in the United States. The film has sparked significant controversy surrounding racism in the United States, focusing on its negative depiction of black people and the glorification of the Ku Klux Klan. Today, it is both acclaimed for its radical technique and condemned for its inherently racist philosophy.
