The location must have seemed extra special even then, because Texas Trail was the only one of the 66 Hoppy films made between 1935 and 1948 to shoot outside California - most were made at Lone Pine or Kernville, north of Los Angeles. With the rights to the Hoppy films passed around like a hot potato over the years and production records having scattered to the wind, we have yet to discover what prompted the one-time excursion to Arizona. Perhaps Texas Trail's producer, Harry Sherman, was aware of Universal Pictures' Stormy which had a similar plot element involving a massive movement of wild horses and was filmed at many of the same spots in 1935; maybe he simply decided to take advantage of location scouting legwork that already had been done?
