The Blocked Trail was one of six "Three Mesquiteers" westerns starring Bob Steele, Tom Tyler and Jimmy Dodd. Steele played Tucson Smith, Tyler was Stony Brooke, and Dodd (later famous as the head mousketeer on TV's Mickey Mouse Club) essayed the comedy-relief role of Lullaby Joslyn. The plot of this 6-reel sagebrusher was nothing out of the ordinary, save for a clever gimmick: a "seeing-eye" horse. When a miner is murdered, the dead man's horse is the only individual who can lead both heroes and villains to a hidden mine. Two more "Three Mesquiteers" oaters would be churned out by Republic Pictures before the studio retired the long-running (51 episode) series.
