This aired on April 14 on PBS and is available free online till May 5th.
One of the better documentaries on Ali's often documented life. It's currently rated 91% fresh on Rottentomates with the critic's consensus being "Director Bill Siegel doesn't explore any new boundaries of the documentary with The Trials of Muhammad Ali, but his subject is so inherently fascinating that the movie proves gripping in spite of its familiar beats."
This should be required viewing for any boxing fan and gives context and better insight into Ali's religious views, racial outlook, and wartime dissent.
After watching, feel free to discuss in the comments.
