"Trail Dust" is a pleasing example of how a simple "formula" western can, with a bit of imagination and a good cast, can be turned into a first-rate adventure. Hopalong Cassidy, together with his usual sidekicks Windy and Johnny Nelson, volunteer to sell their herd at a reasonable price during a food shortage. This does not set well with some greedy cattlemen (led by Morris Ankrum, who was to become a familiar staple in later Hopalong adventures, usually as an unctuous villain). The bad guys set out to sabotage the cattle drive at every turn, and the action scenes are vintage Hopalong Cassidy. There are some pleasant diversions along the way - including an understated Beth Clark - and the climatic denouement seems a natural to the scenes which precede it. There is a little singing along the way, but - as in most of the early Cassidy movies - the music is pleasant, authentic to its genre, and does not interfere with the plot or action. Also, Trail Dust contains some good scenes of cattle-droving, using some real-life cowboys. Quite Enjoyable.
