[about filming of
The Great Sioux Uprising (1953)] We were on location in Pendelton, Oregon, where they had the Yumatilla Indians, not the Sioux tribe. These people were into harvesting winter wheat, and they knew nothing of horses, like the Sioux did. In fact [laughs], they kept falling off! There was an ambulance standing by because these poor Indians who wanted to be in the movie, simply couldn't ride a horse!
