Watch VoirFilms. In 1915, Boston-based African American newspaper editor and activist William M. Trotter waged a battle against D.W. Griffith’s technically groundbreaking but notoriously Ku Klux Klan-friendly The Birth of a Nation, unleashing a fight that still rages today about race relations, media representation, and the power and influence of Hollywood. Birth of a Movement, based on Dick Lehr's book The Birth of a Movement: How Birth of a Nation Ignited the Battle for Civil Rights, captures the backdrop to this prescient clash between human rights, freedom of speech, and a changing media landscape.
