Once Upon a Time in Harlem is a 2026 American documentary film built from footage shot in 1972, directed by William Greaves and David Greaves and produced by Liani Greaves and Anne de Mare. It had its world premiere in the Premieres section of the 2026 Sundance Film Festival on January 25, 2026, screened in the Directors' Fortnight section of the 2026 Cannes Film Festival, where it was nominated for the L'Oeil d'or, and was theatrically released in the United States by Neon on October 16, 2026. Its running time is 100 minutes. In the CultureTechLens graph it is the documentary record of the Harlem Renaissance Reunion Party (1972), and David Greaves, William Greaves, and the artists who appear in it are its principal linked nodes.

The Sundance Institute, in its festival coverage, describes the film as opening on an intimate gathering in 1972 at the Harlem home of Duke Ellington, where artists of the Harlem Renaissance came together for an afternoon of reflection and connection. What begins as a cocktail party becomes, in Sundance's words, an archive of memory, debate, and the wisdom of a generation that helped define Black cultural identity in America. The gathering was orchestrated by the late William Greaves, whose earlier films Symbiopsychotaxiplasm: Take One, Ralph Bunche: An American Odyssey, and Symbiopsychotaxiplasm: Take Two and a Half had all screened at Sundance. Co-directing alongside his father is David Greaves, who was also behind the camera during that afternoon in 1972; reference listings credit cinematography to David Greaves, Doug Harris, David Hoffman, and Jerry Pantzer, among the four camera operators who filmed the party on 16mm.

The scale of the surviving material explains the film's fifty-year gestation. Editor Lynn True and editor and producer Anne de Mare pieced the film together from nearly 60,000 feet of film, and later coverage describes David Greaves restoring and completing nearly thirty hours of footage into the finished hundred minutes. William Greaves had set the project aside: still photographs from the period were incorporated into his 30-minute 1974 documentary From These Roots, but the live-action party footage did not match the stills aesthetically and sat unused for decades. After William Greaves died in 2014, his widow Louise Archambault Greaves obtained a Ford Foundation grant to digitize and assemble the archive, and before her own death in 2023 she handed the project to David Greaves and his daughter Liani Greaves to complete with de Mare. The music is by Tamar-kali, and the production company is William Greaves Productions.

The people on screen are the film's subject. Festival and review coverage names, among the guests, the painter Aaron Douglas, the writer and painter Richard Bruce Nugent, the artist Romare Bearden, the composer Eubie Blake, who co-wrote the landmark Black Broadway musical Shuffle Along, the photographer James Van Der Zee, the poet Arna Bontemps, the actor Leigh Whipper, the activist Louise Thompson Patterson, the librarian Regina Andrews, the musician Noble Sissle, the society editor Gerri Major, and Ida Mae Cullen, widow of the poet Countee Cullen, who advocates in the film for her late husband's legacy. In the CTL graph, Eubie Blake, Regina Andrews, Noble Sissle, Gerri Major, Romare Bearden, Ida Mae Cullen, Richard Bruce Nugent, and James Van Der Zee are linked to the film as appearing in it, along with Frank Horne, whose graph link is carried from the CTL record. Reviews note the conversations' range: guests who had not seen one another in decades reminisce and argue over Marcus Garvey, over whether to say Negro or Afro-American, over Claude McKay's 1920 poem The Lynching, and over how their generation's work should be judged, against the background of lynching, the Ku Klux Klan, and the assassinations of Martin Luther King Jr. and Malcolm X.

Reception has treated the film as both a documentary and a recovered archive. It won the Library of Congress Lavine/Ken Burns Prize for Film, a 200,000 dollar award, as an official selection of the 2026 Sundance Film Festival, and its festival run extended to Telluride, the Toronto International Film Festival, the BFI London Film Festival, and the New York Film Festival. For CTL, the film is a primary moving-image source for the Harlem Renaissance generation speaking in its own voice, and its graph value is the density of its links: two directors across two generations, a named producing team, and a roomful of Renaissance artists whose individual records the party connects in a single afternoon.
