Once Upon a Time in Harlem is a 2026 American documentary film directed by William Greaves and David Greaves. It follows a gathering of the surviving members of the Harlem Renaissance in 1972. It remained unfinished for more than fifty years, until David revisited the footage following his father's death.
The film had its world premiere at the Premieres section of the 2026 Sundance Film Festival on January 25. It also screened at the Directors' Fortnight section of the 2026 Cannes Film Festival, where it was nominated for the L'Œil d'or. It was theatrically released in the United States by Neon on October 16 and received widespread acclaim from critics.
William Greaves presents footage of a 1972 party he convened at Duke Ellington’s townhouse in Harlem with living luminaries of the Harlem Renaissance, an event he regarded as the most important he captured on film. Greaves invited every surviving participant he could locate. Many had not seen one another for decades. They included the painter Aaron Douglas; the artist and writer Richard Bruce Nugent; the poet Arna Bontemps; the musicians Eubie Blake and Noble Sissle; the photographer James Van Der Zee; and Ida Mae Cullen, the widow of Countee Cullen. They also included society editor Gerri Major, poet Frank Horne, artists Romare Bearden and Ernest Crichlow, actor Leigh Whipper, librarians Jean Blackwell Hutson, and Regina Anderson, theatrical producer Irvin C. Miller, historians Nathan Huggins and John Henrick Clarke, activist Richard B. Moore, journalist Ted Poston, and writer George Schuyler.
They discuss other key figures who had passed including Marcus Garvey, Langston Hughes, Zora Neale Hurston, Claude McCay, Paul Robeson, and Augusta Savage.

Principal photography took place in August 1972, led by independent documentarian and experimental filmmaker William Greaves. Aged 26 at the time, David Greaves was part of the camera crew, working alongside Doug Harris, David Hoffman, and Jerry Pantzer.
The documentary was shot in 16mm film, using a trio of Éclair 16mm NPR (Noiseless Portable Reflex) cameras, alongside a Bolex H16 16mm as a fourth camera. Two sound recordists captured the audio to tape.
After William passed away in 2014, his widow and lifelong creative partner, Louise Archambault Greaves, spend her later years trying to assemble funding for the preservation of his body of work, securing grants from the Ford Foundation, the Cromwell Harbor Foundation, and the Mellon Foundation.
The documentary footage, comprising around 60,000 feet of film (around 30 hours of footage), was only rediscovered 50 years later after being taken out of deep storage. American preservation specialist Bill Brand worked to restore and digitize the original footage during 18 months in New York City. While the audio archived in the Schomburg Center for Research in Black Culture in Harlem was resynced into the 4K-scanned film.
The material was later cut by Anne De Mare (also credited as producer) and Lynn True, with color grading by Stewart Griffin, in a process overseen by David Greaves (credited as co-director), and William's granddaughter Liani Greaves (credited as producer).
ElevenLabs software was used to generate 90 seconds of audio in the voice of William Greaves.
