Muhammad Ali

Round Four: The Spell Remains (1974-2016)

Muhammad Ali shocks the world when he defeats George Foreman in Zaire, winning back the heavyweight title and becoming the most famous man on earth. He faces Joe Frazier in the brutal "Thrilla in Manila," and boxes for five more years. He is diagnosed with Parkinson's in 1984 but continues to travel the world spreading his Islamic faith, and becomes a symbol of peace and hope.
