Neon Drops Trailer for 'Once Upon a Time in Harlem,' a Documentary 50 Years in the Making

Neon has released the trailer for its Oscar-contending documentary Once Upon a Time in Harlem, a film more than 50 years in the making that captures a 1972 gathering of surviving members of the Harlem Renaissance (Deadline).

The film opens theatrically on 16 October 2026 at Film Forum in New York, with Neon confirming the date across its official channels (Deadline; Neon). A teaser trailer has been live on Neon's YouTube channel since June, its description stating the film opens in select theatres on that date (YouTube).

The documentary was conceived and filmed by the late William Greaves, a towering figure in American documentary filmmaking, and completed by his son David Greaves, who directs. William Greaves' centenary — his 100th birth anniversary — falls on 8 October, just over a week before the theatrical opening (Deadline).

The family thread runs through the production. Liana Greaves, William's daughter, produces alongside Anne de Mare. The edit is by Lynn True and Anne de Mare, with music composed by Tamar-kali (Deadline).

What the film documents is itself a piece of cultural archaeology. In 1972, William Greaves filmed a reunion of surviving figures from the Harlem Renaissance — the flowering of Black art, literature and music centred on the New York neighbourhood in the 1920s and 1930s. The footage sat unfinished for decades. Now restored and shaped into a feature, it preserves a conversation among people who were there when the movement happened.

The festival run has been extraordinary by any measure. Once Upon a Time in Harlem screened at Telluride on the festival's recent weekend, and it is reported to be the only film this year programmed at Sundance, Cannes, Toronto, the New York Film Festival and Telluride — a clean sweep of the five most prestigious festivals on the circuit (Deadline).

For a documentary without a celebrity subject or a true-crime hook, that kind of festival presence is rare. It signals strong critical enthusiasm and positions the film as a serious awards contender — the kind of specialised release Neon has built its name on, from Parasite to Anatomy of a Fall. The distributor has made awards-season strategy a signature, and a documentary arriving with five major festival laurels on 16 October lands squarely in that corridor.

The timing is precise. William Greaves' centenary on 8 October gives the release a natural memorial peg. The film opens eight days later. Awards voters will receive screeners in the thick of autumn consideration. And a documentary about the Harlem Renaissance, completed by the film-maker's own family, arrives in a year when conversations about whose stories get preserved — and who gets to tell them — sit at the centre of the cultural conversation.

Whether that translates into nominations is a question for December. What is certain is that a piece of footage captured in 1972 is finally reaching screens, more than half a century later, in the form its original author intended.
