The Greatest trailer is out, and it starts Muhammad Ali’s story where most retellings skip ahead: with a kid from Louisville named Cassius Clay. Prime Video dropped the trailer and key art on October 14. All eight episodes arrive November 4, exclusively on Prime Video. It’s the first authorized scripted series about Ali’s life, and his widow, Lonnie Ali, is an executive producer.
What The Greatest Trailer Shows
The footage follows young Clay through the personal, professional, and political battles he fought inside and outside the ring. Prime Video pitches it as a once-in-a-generation talent fighting for the right to become his own man. The backdrop is a changing America. That’s a deliberate choice, because Ali’s career has been covered exhaustively, but the years before the legend hardened get far less screen time.
Then there’s the Sonny Liston factor. Ali beat Liston twice, in 1964 and 1965, and those fights anchor any Ali story worth telling. Essence notes that the series also tracks how his beliefs put him at odds with what American society expected of him. So the trailer isn’t only about boxing. It’s about what the fighting cost him, and who he became while he paid.
Jaalen Best Steps Into the Role
Jaalen Best stars as Clay, and this is his first lead role. He’s 28, and viewers may remember him from All American: Homecoming, where he played Ryan Craig, a journalism student at the fictional HBCU Bringston University. Now he’s stepping into one of the most recognizable voices in sports history. That’s a steep climb, but the production gave him a long runway. Prime Video ordered the series in July 2024, and it was built in collaboration with Ali’s estate.
Matching Ali means more than a good impression. It means footwork, rhythm, and the kind of charm that made a heavyweight feel like a poet. Best has to sell all of it while the camera stays close on a young man who isn’t a legend yet.
The Cast Around Him
The supporting lineup is deep. Omari Hardwick plays Cassius Clay Sr. and is known for Power, with recent turns in Star Trek: Section 31 and The Mother. Dana Gourrier plays Odessa “Bird” Clay, after turns in P-Valley and Interview with the Vampire. Kai Parham plays Ali’s younger brother, Rudy Clay, and Giovanni Ribisi plays trainer Angelo Dundee. Michael Ealy plays Malcolm X in a recurring role, while Erica Tazel appears as Liston’s wife, Geraldine.
Amin Joseph stands out in the Liston role. He played Jerome Saint across all six seasons of Snowfall and directed the episode “Ballad of the Bear.” More recently, he starred in One of Them Days opposite Keke Palmer and SZA. That mix of menace and range is exactly what a Liston needs.
Who Built It
Ben Watkins created the series and serves as showrunner. He’s also the creator of Cross, and his Blue Monday Productions is on the credits. Michael B. Jordan’s Outlier Society is a producing partner too, and its president, Elizabeth Raposo, is an executive producer. So are Authentic Brands Group’s Corey Salter, Matthew Gross, and Marc Rosen, along with Desiree Perez of Roc Nation. Prime Video says the series had unprecedented access to Ali’s estate. Prime Video’s series page also lists Authentic Studios, Roc Nation, Shawn Carter, Polygram Entertainment, and Grace: A Storytelling Company.
Watkins told Deadline in June that the series would reveal what “wasn’t in documentaries.” The trailer backs that up. Instead of leading with title fights, it leads with a young man still figuring out who he is.
The HBCU Buzz Connection
This isn’t HBCU Buzz’s first run with Watkins’ work. In 2024, the site teamed up with Prime Video for exclusive HBCU screenings of Cross. Those events landed at Morehouse’s Ray Charles Performing Arts Center in Atlanta, Cramton Auditorium at Howard in Washington, D.C., and a Chicago venue. Aldis Hodge joined the first two stops for Q&A sessions.
The Greatest already has its own HBCU moment. On October 12, HBCU House, HBCU Buzz’s events platform, joined Prime Video at Manifest in D.C. for The Greatest Mile, one of the first events of Howard Homecoming Week. The event teamed up with 1867 Run Club. Best, Parham, and Joseph all showed up, and the evening took its theme from Ali’s legacy of confidence, discipline, and purpose.
The format kept things social. Workouts, a community mile, and plenty of time to connect brought students and D.C.’s wellness community into the same room. DJ Wildchild and Kyle on the Mic kept the energy up, while partners included Sweat DC, Tech Wellness, TNDM, Run Grl Co., Good Baudi, and Tao Run Club.
One moment belonged to the culture. HBCU House presented The Key to the House to Anthony “Cool Ant” Williams, continuing a tradition of honoring HBCU graduates whose leadership and service open doors for the next generation. In a week built around legacy, that fit.
How to Watch
Prime Video will release all eight episodes at once on November 4, in more than 240 countries and territories. That’s a full binge drop for a limited series, so there’s no waiting a week between chapters. Prime Video’s release lists Instagram accounts @CultureRatedPV and @MuhammadAli, along with @MuhammadAli on X. Use #TheGreatest to follow the conversation.
What to Watch For
The Greatest trailer promises a coming-of-age drama more than a highlight reel. Fight fans will still get their bouts, but the bigger question is whether Best can make a familiar icon feel new. If the performances hold up, the series could change how a new generation meets Ali. And for an audience that already values legacy, discipline, and showing up, the pitch lands before the first episode even starts. With the premiere three weeks away, we’ll know soon enough.
