Befitting its extraordinary and complex subject, The Trials of Muhammad Ali is not a conventional sports documentary. Examining Ali's life outside the ring, beginning with the announcement of his deeply held and controversial Islamic religious beliefs and the decision to change his "white man's name" of Cassius Clay to Muhammad Ali.
Ali refused to serve in the Vietnam War - even after his status as a conscientious objector was denied - on the grounds of protesting racial injustice at home.
It is easy to understand why Ali was such a controversial, charismatic and influential figure, not only in the sporting arena, but in world history generally.
