Filme baseado na biografia Bill The Boy Wonder: The Secret Co-Creator of Batman, escrita por Marc Tyler Nobleman. O livro afirma que Bill Finger foi responsável por criar 98% do que conhecemos sobre o Batman, incluindo a roupa, diversos vilões e até o termo “Dark Knight.”
Everyone thinks that Bob Kane created Batman, but that’s not the whole truth. One author makes it his crusade to make it known that Bill Finger, a struggling writer, actually helped invent the iconic superhero, from concept to costume to the very character we all know and love. Bruce Wayne may be Batman’s secret identity, but his creator was always a true mystery.
