"Muhammad Ali the Greatest" (1974) is an unorthodox documentary made by Paris-based painter-photographer-filmmaker William Klein, and it should not be confused with the big-budget Hollywood biopic "Ali" starring Will Smith, or the entertaining documentary "When We Were Kings" about the Rumble in the Jungle, or the inspiring made-for-British-TV documentary "Muhammad Ali - Through the Eyes of the World." All of these films about boxing great Muhammad Ali are worth seeing, but as far as I am concerned, "Muhammad Ali the Greatest" is easily the best of the bunch.Directed by: Klein, WilliamRunning time: 94Year: 1974English
