Covered Wagons on Catalina
On March 16, 1923, the silent movie The Covered Wagon was released. Part of this movie was filmed on California's Santa Catalina Island, according to Lee Rosenthal in her book Catalina in the Movies, 2003.
Many of the covered wagons in the film were authentic, and the people riding in them were descendants of actual pioneers. In a way, it was an early reality production.
