During the 1930s-1950s, Hollywood made 147283401324 B-westerns--such as those with Roy Rogers and Gene Autry. However, there were many, many more B series westerns as well with the likes of Hopalong Cassidy, Lash LaRue, the Cisco Kid and many, many others.
This film stars Larry "Buster" Crabbe--ex-Olympic swimming champion and low-rent actor who played Buck Rogers and Flash Gordon in serials. While few would know it today, he actually made quite a few low-budget westerns and west definitely NOT among the better movie cowboys--though he was tall and had nice clean clothes. Now considering that "His Brother's Ghost" was made by one of the crappiest of the 'Poverty Row' studios, it's actually surprisingly good--which, really, isn't saying much! After all, most of these series films really didn't have great plots nor were the actors that great either. They were simply churned out by the dozen and undiscerning audiences loved 'em.
In this film, despite Crabbe getting top billing, the star seems to be Al St. John. If you don't know, St. John was one of Fatty Arbuckle's relatives and played his foil in many silent comedies. In the 1930s and 40s, St. John had re-invented himself as a cowboy sidekick and was kept very busy in this capacity.
The film starts with the usual rich baddies trying to run out all the ranchers. One of the most recalcitrant of the ranchers is play by St. John and the other ranchers look to him to lead a fight against the forces of evil. But, when he is killed, the cause for niceness is given a severe blow. Crabbe, though, has an idea--to get St. John's identical twin(!) to pretend to be him! This is very contrived but also a bit funny--injecting a tiny bit of life into this otherwise routine film. While you might balk at my giving it a 3, most of these films deserved 3s as they lacked imagination and depth and were meant mostly for little kids.
