In 2001, Greaves released one of his most ambitious works "Ralph Bunche: An American Odyssey". According to Greaves, between attempting to securing funds and researching countless old manuscripts, photos, and newsreel footage, the film took him ten years to make. The final product was edited down from an initial cut of seventeen hours to two hours for the PBS show American Odyssey. The final project, narrated by Sidney Poitier, sought to bring the name of Ralph Bunche back into the public lexicon as Greaves felt he was an important, yet forgotten, political figure, one important to African-American history and the Civil Rights Movement.
