This is another documentary on Muhammad Ali's most famous bouts. Unlike previous ones, it contains interviews with Ali's fiercest opponents like Joe Frazier, George Foreman and Ken Norton. They give interesting information on the fights that doesn't exist in previous documentaries. One thing I didn't like is that the transition between interviews are very quick and after some time the name of the boxer is not displayed so I had difficulty distinguishing them. Otherwise, the documentary is valuable as it contains first-hand accounts.
