Prime Video announced over the 4th of July weekend that The Greatest, its highly anticipated scripted series about the life of Muhammad Ali, will premiere November 4, 2026, in more than 240 countries and territories worldwide. The announcement came during a special first-look presentation at Essence Festival of Culture in New Orleans, moderated by ESPN and ABC News journalist Kelley Carter.

Creator, showrunner, and executive producer Ben Watkins joined cast members Jaalen Best, Dana Gourrier, Amin Joseph, Kai Parham, and Michael Ealy on the Essence mainstage. Attendees received an exclusive first-look teaser during the event.

Best stars as Cassius Clay and Muhammad Ali in the eight-episode series, which is described as an intimate exploration of Ali’s life as a boxing champion, humanitarian, and global icon.
