Made in the final years of the serial format, Blackhawk didn't have the budget power to fully realize the popular comic book character. Still worth a watch, though, as Kirk Alyn was always super in his roles. Here's the exciting pressbook used to promote the movie to theaters. The title change (The Miraculous Blackhawk: Freedom's Champion to Blackhawk: Fearless Champion of Freedom) happened when home video kicked in, according to the wiki article. Miraculous is a bit presumptuous, when you think about it.
