Step-by-step explanation:
The statement is True. D.W. Griffith's incredible innovations in filmmaking were indeed overshadowed by the racist content of his most important film, The Birth of a Nation. This film, released in 1915, depicts negative stereotypes about Black people and portrays Black males as sexually unrestrained towards White women. The film's racist content led to significant controversy and the revival of the Ku Klux Klan. Although the National Association for the Advancement of Colored People (NAACP) tried to ban the film, their efforts were unsuccessful.
