Harlem Renaissance documentary finally gets global premiere 50 years after cameras rolled

The documentary Once Upon a Time in Harlem has received its international premiere at Cannes’ Directors’ Fortnight on May 16, 2026. The film arrives more than 50 years after the original footage was captured, offering a delayed but significant window into the legacy of the Harlem Renaissance.

The production was originally conceived and filmed by pioneering documentarian William Greaves. Following his death in 2014, the project was completed by his son, David Greaves, and his granddaughter, Liani Greaves.

The documentary focuses on a specific event: a cocktail party hosted by Greaves in August 1972. The gathering took place at the Harlem townhouse of Duke Ellington and served as a focal point for Greaves to capture the reflections of surviving figures from the Harlem Renaissance.

By 1972, the movement that had transformed Black American culture during the 1920s was already facing the risk of being sidelined. Greaves sought to gather the artists, musicians, writers, and organizers who had built the movement to ensure their voices and perspectives were preserved for future generations.

The project was born out of Greaves’ professional frustration with the state of American media. In 1969, the filmmaker expressed anger regarding the racially degrading stereotypes that white film producers frequently presented on screen.

Greaves believed that the only way to combat these inaccuracies was through Black ownership of the production process. He argued that without Black people producing information for television and film, the representation of Black life would remain skewed.

It became clear to me that unless we black people began to produce information for screen and television there would always be a distortion of the ‘black image.’

William Greaves

Greaves viewed the footage gathered during the 1972 cocktail party as the most important work he ever shot. The event brought together participants who, in many cases, had not seen one another in decades, creating a unique environment for reflection on the cultural shift they had spearheaded half a century earlier.

The completion of the film by David and Liani Greaves ensures that the original intent of William Greaves is realized. The premiere in Cannes marks the first time the global film community has had access to this specific archival record of the Harlem Renaissance’s living architects.

The timing of the premiere highlights the enduring nature of the footage and the ongoing necessity of the documentary’s mission. By bridging the gap between the 1920s movement, the 1972 recording, and the 2026 release, the film serves as a multi-generational archive of Black intellectual and artistic achievement.

The film’s presence at Directors’ Fortnight underscores the industry’s recognition of Greaves’ role as a pioneer in the documentary field and his commitment to correcting the historical narrative of Black Americans through the lens of a camera.
