Will Smith portrays the famous boxer believably and credibly. He was an amazing fighter and his turning to the Nation of Islam is portrayed factually. The scenes on the south side of Chicago in the 50’s were realistic and done on location. Muhammad Ali’s life of discipline, with the rewards of enormous money is juxtaposition against a fierce desire to win: but he doesn’t win in his relationships of love. This is good viewing and also good history for gen x’ers. Obviously, there’s going to be violence in a movie telling the story of a heavyweight boxer’s rise to fame and fortune. The violence is in context: he’s fighting to either get or maintain his title of Heavy Weight Champion of the World.
