This was the second entry in Pine-Thomas' film series based on the popular radio show Big Town. Philip Reed and Hillary Brooke return respectively as Steve Kilgore, crusading editor of the Illustrated Daily Press, and Steve's plucky Gal Friday Lorelei Kilbourne. In this one, Steve suspects that hard-luck Harry Hilton (Frank Wilcox) has been framed on a murder rap. Investigating on his own, our hero uncovers a conspiracy to bring financial ruin to a construction firm. He also discovers that the person behind it all is the actual murderer. A few scattered laughs are provided when Lorelei faces male chauvinism upon taking over the responsibilities of the Daily Press' police-beat reporter. To avoid confusion with the television version of Big Town, I Cover Big Town was retitled I Cover the Underworld for TV. ~ Hal Erickson, Rovi
