Prime Video's new 8-part biopic traces a legendary boxer's rise, exploring family, faith, and the convictions that shaped him into a cultural icon. Released in full on Wednesday, November 4, 2026, this fantastic new docudrama paints a portrait of not only one of the greatest athletes to ever live, but also one of the most influential figures of the 20th century. Executive produced by Jay-Z and Michael B. Jordan, this Prime Video series has quickly established itself as one of the most definitive portrayals of 3-time heavyweight boxing champion Muhammad Ali. Prime Video's new 8-part docudrama series The Greatest is one of the best modern examples of how to properly adapt the life and career of a legend such as Muhammad Ali. With its perfect 100% Rotten Tomatoes score, The Greatest is a shining example that sets a new standard for all future sports drama adaptations and biopics told over 8 episodes. Created by Ben Watkins (Cross, Hand of God, Burn Notice), The Greatest instantly lives up to its name with its breakout performance by Jaalen Best, who portrays Cassius Clay/Ali, along with a stellar ensemble that includes Giovanni Ribisi, Joel Keller, and Omari Hardwick. The Greatest Explores The Years That Turned Cassius Clay Into Muhammad Ali The Greatest is much more than just a beat-by-beat retrospective on one of the most well-documented careers in sports history. Instead, it narrows in on one of the most transformative and prolific periods in the life of Cassius Clay, precisely concentrating on the four years between the athlete's gold-medal victory at the 1960 Olympics in Rome, Italy, and his historic victory over reigning heavyweight champion Sonny Liston in 1964, which earned Clay his first heavyweight boxing title. By centering on this brief period of Clay's 74-year life, viewers are taken along for the ride as he lives up to his remarkable potential from ages 18 to 22. What's more, The Greatest examines the cultural pressures and social norms of the era, which were plagued by racial discrimination and various political tensions across the United States. It's impossible to accurately tell the story of Cassius Clay without these considerations, as they would come to shape so much of his identity, both inside and out of the boxing ring. The Greatest also revisits Clay's relationship with Malcolm X, portrayed by Michael Ealy, who heavily influenced Clay's perspective on religion, spirituality, and civil rights. These beliefs would become an integral part of Clay deciding to change his legal name to Muhammad Ali, even though he and Malcolm X cut ties in 1964, just one year before that latter figure was assassinated. The Greatest Goes Beyond The Ring To Identify The Man Behind The Legend Most would agree that the years between 18 and 22 become some of the most significant in just about every person's life, and The Greatest maintains a laser-sharp focus on Clay during this time as he develops into the monumental figure he is remembered as today. That said, Clay's success story, rising to international fame, is extremely rare in its own right, and the 8-part Prime Video series honors the immense difficulties that Clay faced during this period to clearly identify the man before he became the legend. This creative choice is an exceptional reminder that a proper docudrama doesn't always need to follow a cradle-to-the-grave recounting, and that oftentimes a more acute focus on a public figure's life reveals much more profound detail than a more extensive series possibly could. As FandomWire writes in their 9/10-star review of The Greatest, "Featuring a powerful, magnetic performance from Jaalen Best, The Greatest is a rich, exhilarating portrait of a man whose greatest victories weren't always won inside the ring." Whether you're an avid sports fan or not, The Greatest is an achievement as an 8-part biopic series done right that maintains a serious respect for its subject while prioritizing the historical facts and natural excellence over needless embellishment. As far as the best new shows to watch on Prime Video this week, it does not get any better than The Greatest, available to binge right now.
