In a landmark tribute to one of the most iconic figures in basketball history, Netflix has officially announced the release of “The Underdog,” a deeply personal and highly anticipated documentary chronicling the life, career, and legacy of Boston Celtics legend Bill Russell. The documentary is slated for release on October 15, 2025, and is expected to be one of the streaming giant’s most-watched sports documentaries of the year.

A Legend Revisited
Bill Russell is more than a basketball player—he is a symbol of resilience, leadership, and excellence. With 11 NBA championships in 13 seasons, Russell redefined the center position and revolutionized the way defense was played. But “The Underdog” isn’t just about his statistics or championship rings; it’s about the man behind the legacy—the quiet strength, the fierce intellect, and the courage that defined a generation.
Produced by Emmy-winning filmmaker Ava DuVernay and narrated by Academy Award winner Denzel Washington, “The Underdog” offers never-before-seen interviews, personal footage, and commentary from basketball legends including Kareem Abdul-Jabbar, Magic Johnson, Larry Bird, and current Celtics stars like Jayson Tatum.
A Life Beyond the Court
The documentary delves deep into Russell’s early life growing up in the segregated South, his journey through the University of San Francisco, and the cultural challenges he faced while playing in Boston during the height of the Civil Rights Movement. While Russell was dominant on the court, his impact off it was equally powerful.
From marching with Dr. Martin Luther King Jr. to being one of the first Black head coaches in major American professional sports, Russell used his platform to challenge injustice. Netflix’s “The Underdog” doesn’t shy away from these moments—it confronts them head-on, offering a poignant look at the strength it took to be a Black athlete and activist in an era defined by division.
An Intimate Portrait
What sets this documentary apart is its intimacy. Russell’s own voice, captured in interviews before his passing in 2022, serves as the narrative backbone. His reflections on life, fame, racism, and responsibility provide a window into his thoughts like never before.
In one particularly moving segment, Russell discusses how he often felt like an outsider despite his success. “I was a hero on the court, and a villain off it,” he says. “But I never wanted to be anyone’s hero—I wanted to be a man of principle.”
His relationships—with teammates like Red Auerbach and John Havlicek, with opponents like Wilt Chamberlain, and with the city of Boston itself—are explored with nuance, showcasing a man who was complex, principled, and fiercely private.
Reactions and Expectations
Within hours of the announcement, fans and sports analysts alike took to social media to express excitement and admiration. Celtics president Brad Stevens tweeted, “No one deserves a tribute like this more than Bill Russell. A true giant in every sense.”
NBA Commissioner Adam Silver also released a statement, praising the documentary:
“Bill Russell’s story is one that every generation should hear. We thank Netflix for telling it in such a powerful, respectful, and honest way.”
Netflix has been steadily building a strong lineup of sports documentaries, but “The Underdog” is being positioned as a cornerstone project, aimed not only at sports fans but at anyone interested in American history, civil rights, and personal resilience.
The Legacy Lives On
As the world prepares to revisit the extraordinary journey of Bill Russell, “The Underdog” promises to be more than just a documentary—it’s a celebration of greatness forged under pressure, of dignity in the face of adversity, and of an underdog who never stopped fighting for what was right.
The documentary premieres on October 15, 2025, exclusively on Netflix.
For Celtics fans, NBA enthusiasts, and admirers of social justice icons alike, this is a must-watch event that honors the life of a man who was never just about basketball—but about making the world better than he found it.
