For decades, the seven reels from 1913 lay unexamined in the film archives of the Museum of Modern Art. Now, after years of research, a historic find has emerged: what MoMA curators say is the earliest surviving footage for a feature film with a black cast. It is a rare visual depiction of middle-class black characters from an era when lynchings and stereotyped black images were commonplace. What’s more, the material features Bert Williams, the first black superstar on Broadway. Williams appears in blackface in the untitled silent film along with a roster of actors from the sparsely documented community of black performers in Harlem on the cusp of the Harlem Renaissance. Remarkably, the reels also capture behind-the-scenes interactions between these performers and the directors.

MoMA plans an exhibition around the work called “100 Years in Post-Production: Resurrecting a Lost Landmark of Black Film History,” which is to open on Oct. 24 and showcase excerpts and still frames. Sixty minutes of restored footage will be shown on Nov. 8 in the museum’s annual To Save and Project festival dedicated to film preservation.

“There are so many things about it that are amazing,” said Jacqueline Stewart, a film scholar at the University of Chicago. “It’s the first time I’ve seen footage from an unreleased film that really gives us insights into the production process.”

She added: “It’s an interracial production, but not in the way scholars have talked about early film history, in which black filmmakers had to rely on the expertise and money of white filmmakers. Here, we see a negotiation between performers and filmmakers.” Of the three directors of the film, one was black and two were white.
