Things I did not know or had forgotten about Muhammad Ali that I learnt in the documentary.

The disfiguring, brutalising, torture, lynching and murder of 14-year-old boy Emmett Till had a profound impact on Ali. The mother of Emmett wanted an open casket to show the world what they did to her son.

Ali was so scared of flying he nearly did not go to the Rome Olympics.

The Christian Kentucky based syndicate that signed up Ali when he became professional gave him a salary, 50% purse, training cost and other tax deductions that was unprecedented at the time. They were supporting a clean-living local star in the making. It also stopped the Mob from taking control of his career.

Ali ran in heavy army boots when going on his 4 mile runs.

Sparred 2 rounds with Ingemar Johansson who was preparing to face Patterson but could not lay a glove on Ali and was told to leave.

Made up the story about training under water to get into Sports Illustrated magazine when he was 19.

Ali younger brother fought his first professional fight the same day he fought Liston.

Ali had grown ½ inch for the 2nd Liston fight.

Frazier first met Ali 1966 when he was 14-0 and promised he would be ready to face him in 2 years time.

WBA took the title away from Ali twice.

The only reason Ali was not imprisoned 5 years for not joining the army was because he would have been allowed to have access to the FBI wire taps they had on Martin Luther King and Malcolm X.
