Albert Dekker was one excellent actor, and in this movie shows he was an excellent action star as well.
He and the Duke have one of the fiercest fight scenes ever, yet the Dekker character is still ultimately likable even though he is a pretty rotten scoundrel.
Siding Duke is his frequent co-star, another excellent actor, George "Gabby" Hayes.
Also siding him, as the oil field manager, is a terribly unheralded actor, Grant Withers, as one of the strongest characters on the screen.
Martha Scott was one gorgeous and incredibly talented woman, to repeat, incredibly talented and apparently so recognized by her fellow actors. But, for some strange reason, she did not become that proverbial household name.
Watch her in this movie and you too will wonder why. She is adorable, and has a beautiful and extremely expressive face.
Speaking of adorable: Dale Evans became The Queen Of The Cowgirls, and as co-star and later wife of Roy Rogers, that is how we know her -- mostly. But in this movie she is also the sexy and delightful singer and dancer in the saloon-night club. And what a talent! That she became a major star later is a, these days, surprising and gratifying example of justice. Dale Evans had it all, beauty and talent and our hearts.
John Wayne gives one of his best performances, playing light comedy in much of the first half of the movie, and then his expected action hero thereafter.
And there is plenty of action, beautifully photographed by Jack Marta and beautifully directed by Albert S. Rogell. They make a good team and make this a wonderful film to watch.
And to listen to? Well, it has both Gabby Hayes and John Wayne singing -- not so pleasant, but funny.
The rest of the listening is very pleasant as two women script-writers, Ethel Hill and Eleanor Griffin, produce a superlative script from the original story by Thomson Burtis. Those three writers have created likable and believable characters who speak delightful and also believable dialogue.
Everything works together to produce for us an excellent motion picture experience, and you can see it at YouTube. I hope you do. This is a great movie.
