The covered wagons gathered by Paramount from all over the Southwest were not replicas, but the real wagons that had brought the pioneers west. They were cherished heirlooms of the families who owned them. The producers offered the owners $2 a day and feed for their stock if they would bring the wagons for the movie. Most of the extras seen on film are the families who owned the covered wagons and were perfectly at home driving them and living out of them during the production.
