This is not a biography of Mohammad Ali, but it is his fight against American establishment, There was a great performance by Christopher Plumber but best performance of the movie was Ali's himself. I always remained a fan of Mohammad Ali but after seeing this I have become an even greater admirer of him. At end of movie when presenter asks him what will he do against the people/administration who has taken so many precious years of his life, Ali's answer was description of his whole life. A worth watching movie, not due to historical facts but due to "Ali's Character against Injustice". I would give it 10 but too much focus on unrelated scenes like fight between the clerks convinced me to give it a 9.

It should suffice to observe that Stephen Frears, the crew and cast took on a subject that no other film-maker chose to, and did so commendably. As Justice Harlan, Christopher Plummer also does a very commendable job. I also did not particularly find Mr. Plummer's early performances suitable for the screen, from 'Inside Daisy Clover' to 'Somewhere in Time'. Somehow, the hammiest roles early on were preferable (he does what the script demands as Commodus in 'The Fall of the Roman Empire' and his Atahualpa in 'Royal Hunt of the Sun' is actually much fun: "They EAT Him!"). As his art has matured ('Silent Partner'; 'Dolores Claiborne'; 'The Insider'; 'The Last Station'; 'The Girl with the Dragon Tattoo'), the more I have looked forward to his performances, as here. Still, while I understand the politics of casting better-known actors in leading roles, I regret that Harris Yulin, another great too long under-appreciated in movies who plays Justice Wm. O Douglas, was not cast as Justice Harlan. Mr. Yulin ('Clear and Present Danger'; 'Training Day'; 'Looking for Richard') will always bring to his characters, villains included, a delicate gravitas that does not belie the humanity of their circumstances: different surely, if not better or preferable to Mr. Plummer's characterization - but audiences would certainly have regarded it very well-tailored for him.

The movie was very accurate to the actual story. The use of actual footage from interviews with Ali was very informative and made the movie more creditable. Because the movie was based on the U.S. Supreme Court Justices, there was no need to actually cast someone to play Muhammad Ali and because of this the movie was far better. Because I was just a teenager when the events of this movie actually played out, there is information in the movie that I wasn't aware of, such as Justice John Marshall Harlan II's fight with cancer. The movie is really a must see for anyone who grew up watching the Ali, Forman and Frazier fights of the time. They were the main reasons boxing was so popular in the 70's.

I had a mixed-reaction to this film. It panders to the audience too much, with the workers in the Supreme Court conversing on subjects that would be obvious to them. Also, at some moments it feels like the plot is jumping from one moment to the next, rather than moving along seamlessly. My third criticism is that it glosses over the likely fact that Ali didn't want to go to the Vietnam War because he didn't want to fight. The movie gives the inaccurate impression that the boxer stood purely on religious grounds. However, that is not what the film is about. It was assumed by the Solicitor General that Ali was honest with his convictions, and this work concerns a fight in the highest court.The main reason to see the HBO movie is Christopher Plummer's fantastic performance as Justice John Marshall Harlan. He plays a reflective man nearing the end of his life beautifully. Christopher and Frank Langella, who plays Chief Justice Warren Burger, have some great scenes together. Additionally, there is some well-chosen historical footage of Ali speaking to the media. If you're a fan of politics or just want to see Plummer knock one out of the park, you will probably enjoy Muhammad Ali's Greatest Fight; but, I think it is overly simplistic.
