First of all an interesting footnote, Tony Lo Bianco played Marciano in a 1979 tv film and also appears in this one as slimy mobster Frankie Carbo (he plays a really detestable character). This is a great film about the real life Rocky. Someone once fed some facts about boxing champions into a computer and the computer said Rocky was the greatest champ of all time. This can be debated of course, but this film shows him as not only a great boxer but as a humble, decent human being who literally started out with nothing. It made me angry watching this film as to how poor Italian immigrants like the Marcianos were treated as second class people and labeled as "dagos". In one of his last performances, George C. Scott is wonderful as Marciano's father. There is one mistake in this film, however. It shows Marciano visiting his friend Joe Louis in a Denver mental hospital. In fact, Joe Louis wasn't committed to this hospital until 1970 a year after Marciano was killed in a tragic plane crash.
