On the Shoulders of Giants — the story of the greatest team you never heard of — is a film created by Kareem Abdul-Jabbar that arrived on the national scene through Video on Demand on major cable outlets in February 2011 and was also introduced to high schools across the country during Black History Month. The documentary shines a long-overdue spotlight on a piece of American sports history that has too often been forgotten.
In 1939, the world of professional basketball was deeply segregated. Black teams could compete against white teams, but they were barred from championships and from shared leagues. Amid this inequality stood the Harlem Renaissance Big Five, better known as the Harlem Rens — widely regarded as the best Black basketball team of their era. The film chronicles how they rose above extraordinary obstacles, from pervasive racism to the hardships of the Great Depression, and still managed to become world champions. Their extraordinary victories against the top white teams of the time helped them redefine what Black athletes could achieve on a national stage, and they served as enduring role models for Black America.
Yet the Rens’ triumphs did not translate into lasting public recognition. They are depicted as one of the most important but least remembered chapters in sports history, their story largely untold to broader audiences even as other Black champions of the era, like Jesse Owens or Joe Louis, maintained a more visible presence in popular memory. On the Shoulders of Giants works to close that gap by recounting how the Harlem Rens not only shattered statistical odds but also provided a powerful source of pride and possibility for generations of Black Americans.
The film’s mission goes beyond retelling a victory tale. It aims to revive a crucial slice of Black history and to ensure that Black heroes from sports, music, literature, and culture stand as visible figures for young people to admire and emulate. By centering the Harlem Rens’ story within the broader tapestry of the Harlem Renaissance, the documentary connects athletic achievement to broader social progress, highlighting the enduring impact of Black excellence on American society.
Accompanying the film is a high school educational program developed by the Skyhook Foundation, an initiative associated with Kareem Abdul-Jabbar. The study guide crafted for this program carries endorsements from the National Council for the Social Studies (NCSS) and enjoys support from UCLA for distribution to social studies teachers nationwide. The goal of this educational material is clear: to deepen U.S. high school students’ knowledge and awareness of the Harlem Renaissance and the pivotal figures who shaped sports, music, literature, and history during that era.
Together, the film and its educational outreach seek to preserve an essential piece of Black history and to offer new generations a source of inspiration through the example of the Harlem Rens. It is a thoughtful invitation to recognize and celebrate the athletes, pioneers, and communities that challenged segregation and helped lay the groundwork for broader social change in America.

In the late 1930s, professional basketball is a segregated arena where black teams can play, but they are barred from championships and the mainstream leagues that define the sport’s glory. The film opens against the backdrop of the Great Depression, a country still wrestling with deep racial divides, and it paints a world where the clatter of basketballs on hardwood courts is both a pastime and a quiet battleground for equality.
At the heart of this world is the Harlem Renaissance Big Five—better known as the Harlem Rens—an assemblage of extraordinary talent and unyielding ambition. Their name reverberates through the streets of Harlem, a community buzzing with music, art, and the relentless drive of a people yearning for recognition. The Rens are more than a team; they are a symbol of hope for Black America, embodying the desire to claim a place on the national stage despite the obstacles erected by prejudice and economic hardship.
Narrated with reverence by Kareem Abdul‑Jabbar, the tone balances gritty realism with soaring inspiration. The cinematography leans into the sepia‑toned elegance of the era, while the score mixes period jazz with modern accents, hinting at the timeless resonance of the story. The film’s mood is both reflective and assertive, inviting viewers to feel the weight of the Rens’ aspirations while sensing the electric possibility that comes with each dribble and pass.
Against this vivid tableau, the Rens prepare to test the limits of a system that refuses to see them as equals. Their journey is framed as a quest for legitimacy, camaraderie, and a chance to rewrite the narrative that has long excluded them. As they step onto courts across the country, the film hints at the profound impact their courage will have—both on the sport they love and on the broader struggle for dignity and representation.
