I have read the 1929 Armitage Trail's noveland this is something that I would recommend also to you, because the book has little in common with the 1932 movie starring Paul Muni.
Because began in the 1916 when the protagonist wasn't yet called Tony Camonte, a name that will take after it had been disfigured during WWI; family thinks that he dead valiantly in combat,for don't humiliate the family will adopt the name of Tony Camonte, while his brother will honestly career in the police, he climbs the top of the Mafia.
Now the book is much more intense that the movie, which at the time seriously risked censorship and not to be screened, and deserves to be faithfully adapted for the cinema.
Don't make useless remake of the remake of DiPalma mvie with other ethnic groups in place of the Cubans.
