Borrowing from his portrayal of Old Man Clanton in My Darling Clementine, Walter Brennan dominates this film as the mean and merciless head of an outlaw family. It seems that Brennan at one time was the local Ben Cartwright, but little by little the homesteaders and small ranches have nibbled him down to little by his standards. So he and his two outlaw sons Jim Davis and Jack Lambert have been plying the outlaw trade going after them with some cattle rustling and other forms of criminal enterprise.
The general outlaw situation has a lot of people mighty of suspicious of sheriff Forrest Tucker and deputy Guinn Williams. Federal Marshal Jack Holt arrives on the scene, but he's wounded in a stagecoach holdup and not able to do too much.
Into all this mix is a mysterious loner played by Rod Cameron who looks like he's trying to cut himself in on everybody's action, Brennan's and Tucker's. When you're not watching Brennan, Cameron's the one that should be paid attention.
Brennan had a very bad time with John Ford when he made My Darling Clementine, but Ford got a great performance from him. I think Brennan channeled a lot of that into his role here of Brimstone Courteen.
This is a great action western from Republic with quite a bit more plot to it than the usual Republic product for the Saturday afternoon kid market. And you'll not forget Walter Brennan in the title role.
