A previously unseen documentary capturing a pivotal moment in Harlem’s cultural history is set for release more than five decades after it was filmed. “Once Upon a Time in Harlem,” directed by the late William Greaves and completed posthumously by his family and collaborators, will premiere in theaters on October 16, distributed by Neon.

The film centers on a 1972 gathering at Duke Ellington’s townhouse, where a group of artists and intellectuals who contributed to the Harlem Renaissance convened to reflect on the movement’s impact nearly 40 years after its peak. Instead of focusing on formal interviews or dramatic confrontations, Greaves recorded the lively party atmosphere, allowing attendees to share anecdotes and debates over wine and punch. The footage reveals a rich tapestry of personal stories from both renowned figures and lesser-known participants, capturing the intergenerational and communal nature of the Renaissance.

Prominent attendees featured in the film include visual artists Aaron Douglas and Romare Bearden, as well as composers Eubie Blake and Noble Sissle. Other subjects, such as Regina Andrews, a city librarian and confidante to poets Langston Hughes and Claude McKay, and Richard Bruce Nugent, a painter and writer mourning the loss of author Zora Neale Hurston, contribute nuanced perspectives to the narrative. The documentary adopts a non-linear, kaleidoscopic approach, employing techniques like split-screen imagery to evoke the feel of the party itself.

William Greaves, born in Harlem in 1926, was an influential African-American filmmaker and actor dedicated to challenging prevailing narratives about Black Americans. His earlier works include the Emmy-nominated “Still a Brother: Inside the Negro Middle Class” and the experimental “Symbiopsychotaxiplasm: Take One.” Greaves maintained that “Once Upon a Time in Harlem” was his most important project, envisioning it as a theatrical experience that would transcend conventional documentary form. Over the years, he expanded the scope of the film conceptually, intending to trace cultural developments from African origins through the diaspora and into the contemporary era.

Following Greaves’s death in 2014, the footage remained largely untouched until his wife, Louise Archambault Greaves, secured restoration and digitization support. After her passing, William’s son, David Greaves—who originally operated one of the cameras during the party—his granddaughter Liani Greaves, and film preservationist Anne de Mare undertook the task of assembling the final cut. They agreed to preserve the integrity of the original footage without adding narration or further commentary.

The film probes enduring debates from the Harlem Renaissance era, such as varying receptions to Marcus Garvey’s “Back to Africa” movement and conflicts over defining Black art, exemplified by writer George Schuyler’s disagreement with Langston Hughes. Despite initial skepticism about the film’s premise—some questioned whether documenting a conversation among older figures would engage audiences—its reception has been overwhelmingly positive.

Completed in time for the Sundance Film Festival in January 2026, the documentary received critical acclaim and was acquired by Neon after a competitive bidding process. In August, it earned the Library of Congress Lavine/Ken Burns Prize for Film, which includes a $200,000 award.

For the Greaves family and collaborators, bringing this long-held project to fruition affirms William Greaves’s foresight in creating a work meant primarily for future generations. David Greaves reflected, “He was always very conscious of the idea that this film was for the future. Now it gets to be a part of history.”
