By the time Gene Autry made this film, he had been starring in B-Westerns for almost two years, and was right on the verge of being named "Public Cowboy No. 1" for 1937, based on the box-office returns from his movies. He held that honor for six straight years, before entering the U.S. Army Air Force in World War II.
Gene and Buffalo Brady (Hal Taliaferro) are co-owners of a large Western ranch from which cattle are being rustled. Gene and his sidekick Frog Millhouse (Smiley Burnette) set out to try to find the rustlers, at one point changing clothes with two lawmen they have found murdered, to aid in hiding their identities in their search. Their journey brings them into some shenanigans with two attractive ladies, and climaxes with a wild stagecoach chase. And I may be wrong, but I'm fairly sure Gene himself did the transfer from Champ's back to the stage.
Hope I haven't posted any "spoilers" here, because the movie is much better than the other posters here have implied, with their lukewarm descriptions like "OK," "Pleasant enough," etc. And when one posts, "Not up to Autry's usual standard," I'd like to know which "usual standard" of his movies they're talking about, as they almost always say that in their reviews.
By the way: Gene Autry's movies are known for their music -- naturally -- and the credits for this one feature a great, Western Swing-sounding instrumental that I've never heard before or since. The scene behind the music is that of a slam-bang rodeo -- which has nothing to do with the story. Explanation? Beats me! But I sure enjoyed that song!
