The much-anticipated miniseries ‘The Greatest’ has now premiered on Prime Video, offering viewers an in-depth look into the early life of one of boxing’s most iconic figures, Muhammad Ali—known as Cassius Clay in his youth. Jaalen Best, a rising actor, plays the pivotal role of young Ali, and he has received an extraordinary endorsement from the late boxer’s widow, Lonnie Ali.
Prior to landing this influential role, Best, at 28, underwent a rigorous audition process supervised by showrunner Ben Watkins. Reflecting on his journey, Best stated, “I had to go to Ben Watkins’ place, and he awarded me the role by putting me through an additional audition process.” He described the experience as both “crazy” and “special,” especially since meeting Lonnie Ali was a final part of his audition. Lonnie, who married Ali in 1986 and remained by his side until his death in 2016, bestowed her blessing on Best, saying, “He’s the one in more ways than you know.”

The official description of ‘The Greatest’ portrays it as an “intimate exploration” of Ali’s life, showcasing not just his prowess in the ring but also his humanitarian efforts and global influence. The cast includes notable names such as Omari Hardwick, Dana Gourrier, and Kai Parham, who portray the family of young Cassius Clay, along with Amin Joseph, who plays boxer Sonny Liston.
Lonnie Ali commented on her first impressions of Best, asserting that his qualities resonated strongly with her recollections of Ali. “There was something about Jaalen that was instant. I knew, ‘This is the one. He’s Muhammad. He can play this. He’s believable,’” she shared. She highlighted that Best’s “little things” and “idiosyncrasies” made him a fitting choice for the role, stating, “He has a heart like Muhammad.”
In addition to her role as an executive producer on the series, Lonnie Ali played a crucial part in the casting decision for Best. She felt he embodied many traits that were reminiscent of her late husband, insisting that Best would make Ali relatable to audiences. Her insight and support have proved invaluable as the series seeks to tell a story about the man behind the legend.

Watkins elaborated on the lengthy casting journey, revealing that the search for the actor to portray a young Ali took over a year. Thousands were considered, and after a meticulous process, Best emerged as one of the finalists alongside three other contenders. The showrunner noted how each time Best was tested, he exceeded expectations, leading to the conviction that he was not simply an actor impersonating Ali, but someone who could genuinely channel his spirit.
“The process included multiple auditions, numerous meetings, and even a physical evaluation,” Watkins explained. He remembered feeling a mixture of anticipation and anxiety about securing Lonnie’s approval, which ultimately came via a text message that conveyed her strong endorsement of Best. “He’s the one in more ways than you know,” were her words that solidified Best’s role in the series.
As ‘The Greatest’ launches into its streaming run, it aims to captivate audiences not just with the athleticism and charisma of the young Ali, but also with the complexities that shaped him into a humanitarian icon. Best’s portrayal, bolstered by Lonnie Ali’s approval and Watkins’ vision, promises to resonate with both fans of boxing and new viewers alike.
As viewers settle in to watch the series, they can expect a portrayal of Muhammad Ali that is both authentic and emotionally engaging, shedding light on the formative experiences that influenced one of the most celebrated athletes of all time. ‘The Greatest’ is now available for streaming, inviting all to experience the journey of a man who would go on to change the world with his fists and his voice.
