I've seen some, although not many and am not a fan of, old B-Westerns, but this one, "Scarlet River," is clever. Besides being a B-Western, it's a film about film, a type of movie I tend to enjoy.
After their filming is repeatedly interrupted by civilization, a film crew rents a ranch for filming their Western. Real-life B-Western star Tom Keene plays B-Western star Tom Baxter, the film-within-the-film's star who is as much of a cowboy on screen as off. In the fictional reality, he kisses the ranch owner and protects her interests against the baddies trying to steal her property and helps her raise her younger brother (including by spanking him for smoking) in between his acting. The ranch owner watches him filming scenes, including him kissing his on-screen romantic interest, and wants to be with him, while her younger brother watches his stunt work and wants to be like him. To save the day, the actor playing an actor acts once more over by donning makeup to pretend to be one of the baddies.
Really, Yakima Canutt, who also has a bit part in the film, did the stunts for "Scarlet River," but, for the film-within-the-film, Tom Baxter does his own stunts, except for one. For that one, one of the baddies (played by Lon Chaney Jr., before he turned to monster movies) tries to do a stunt for the absent Baxter, but fails. Really, Canutt did that one, too--a famous stunt he repeated in "Stagecoach" (1939).
Another interesting character is Ulysses, who has the part of the stuttering comic relief, a common, if bigoted, trope of these types of films. Ulysses is a ranch hand and wannabe screenwriter who writes a script that mirrors the "real" drama of the baddies trying to steal the woman's ranch. Rather than employ him for his writing, the filmmakers use him as comic relief, too. The director also tells Ulysses that if he figures out a trick, he'll hire him. The surrogate author of "Scarlet River" within the film, Ulysses, in the end, solves the trick.
