Muhammad Ali brings to life the iconic heavyweight boxing champion who became an inspiration to people everywhere.

Unprecedented access to Muhammad Ali's personal archive of "audio journals" as well as interviews and testimonials from his inner circle of family and friends are used to tell the legend's life story.

Brash boxer Cassius Clay burst into the American consciousness in the early 1960s, just ahead of the Civil Rights movement. His transformation into the spiritually enlightened heavyweight champion Muhammad Ali is legendary, but this religious awakening also led to a bitter legal battle with the U.S. government after he refused to serve in the Vietnam War. This film reveals the perfect storm of race, religion and politics that shaped one of the most recognizable figures in sports history.
