Jack Holt is impossibly heroic as usual in the Columbia quickie Hidden Power. In his quest to perfect a cure-all for severe burns, Dr. Garfield (Holt) neglects everything else, including his wife Virginia (Gertrude Michael) and son Steve (Dickie Moore). But when Garfield finally perfects the miracle serum, he redeems himself in the eyes of his wife by testing it on his own horribly scarred son. Anyone in 1939 who couldn't see where the story is going from Reel Two should have been drummed out of the theater in disgrace. To add a bit of sidelines intrigue to the proceedings, Henry Kolker plays the villainous Weston, who would use Garfield's amazing discovery for the manufacture of bombs (huh?) ~ Hal Erickson, Rovi
