As indicated by its title, Blue Grass of Kentucky is a horse-racing opus. Bill Williams plays Lin McIvor, the owner of a horse named Blue Grass. He doesn't know it, but the horse was sired by a Kentucky Derby winner, owned by Armistead (Russell Hicks). The aristocratic Armistead had previously refused to mate his prize horse with McIvor's best mare, but the union was orchestrated in secret by Armistead's sympathetic daughter Pat (Jane Nigh). Highlighted by actual scenes from the annual Derby at Churchill Downs, Blue Grass of Kentucky was pleasingly lensed in Cinecolor. The film is ample proof that prolific "B"-flick director William "One Take" Beaudine was capable of turning out first-rate work. ~ Hal Erickson, Rovi
