This movie is hardly a must see and is inevitable the comparison with the harder they fall...keeping as pivot point the story of Primo Carnera there was some pro e some cons:
Pro much more faithfully with the story of Carnera, a good talent that failed to establish himself among the greatest ( thinks mma career of Brock Lesnar) with some shadows in his early career. The movie with Bogart is a totally defamation and is amazing how people take it seriously . The names of the characters are right .
Cons
Not so faithfully..the movie is full of errors and mistakes. The actor puts an effort playing Carnera but he has just the height..as a boxer the style is totally different ( Carnera uses his fine jabs and his right uppercut, this one only direct punches). Antonio Cupo plays a dwarf Baer that is over a full foot shorter then Carnera and half his size ( Baer was a few inches shorter, a giant of his own) with a brutish face, Cupo was choice because is an handsome male model. in others hands Baer cheated during that match and Primo dislocated his ankle at the beginning of the match and the movie portrayed those details.
Judging it as a pure movie it does not lace the boots of Harder they fall.
