I watched this movie this morning on TCM. Brothers in the Saddle (1949) is different than most Tim Holt/Richard Martin B-westerns made during this time period. It's a lot more violent for one thing. For another, Tim plays Tim Taylor, not himself, Tim Holt, as he usually did. Maybe that's because he has a selfish, brutal brother in this one and he didn't want to besmirch the Holt name.
Tim is the foreman of a ranch owned by pretty Nancy Austin (Virginia Cox). His worthless brother, Steve (Steve Brodie) is engaged to Nancy and has been bleeding her for money to cover his gambling losses. Tim covers up Steve's bad side for Nancy. But when Steve kills a crooked gambler in self defense, but is accused of murder. Nancy has to find out. Saloon girl Flora (Carol Forman) can clear Steve, but she ran off to Mexico. To save Steve from a lynch mob, Tim and Chico break him out of jail. Then Tim and Chito head for Mexico to bring Flora back. But while they are gone, Steve robs a stagecoach and murders in cold blood one of the framing gamblers. Tim and Chito bring Flora back, but learn that the stagecoach was held up and they know it had to be Steve who did it. Now Tim and Steve are headed for a final showdown. It's an unusually prolonged and violent one.
Carol Forman plays Flora. She is best known for her role as the chief villainess in the 1947 RKO serial, The Black Widow. Steve Brodie plays Steve. He was in quite a few Tim Holt/Richard Martin B-westerns. Virginia Cox is Nancy. This is her one and only film credit. It's really a mystery how she got the role and what happened to her afterward. RKO had Martha Hyer and Lois Andrews (Mrs. Steve Brodie) under contract at the time and this is the type of role that either could have handled well. Both appeared in several B-westerns. Why it was given to Virginia and why she never appeared in any other movie or TV show doesn't appear to be known. She just dropped out of sight.
Check out Brothers of the Saddle (1949) but be prepared to see a different type of B-Western from Tim and Richard.
