Why has a movie never been done about the life of Hammering Hank Elrod?

A movie about Hammering Hank Elrod has not been made likely due to a combination of factors, including limited mainstream recognition compared to other sports figures and a lack of compelling dramatic narrative in his life story. While he was a notable player, he may not have the broader appeal or cultural significance that draws filmmakers. Additionally, the film industry often prioritizes stories with more extensive documentation or a larger fan base, which may not apply to Elrod's career.
