He is depicted as an everyman who started out by going the distance and overcoming obstacles that had occurred in his life and career as a professional boxer. While he is loosely based on Chuck Wepner, a one-time boxer who fought Muhammad Ali and lost on a TKO in the 15th round, the inspiration for the name, iconography and fighting style came from boxing legend Rocky Marciano.
