The 1956 epic The Conqueror, starring John Wayne as Genghis Khan, was filmed primarily in Utah, with studio interiors completed at RKO Radio Pictures Studios in Hollywood, California. Principal photography mostly took place in and around St. George, Utah, leveraging the region's dramatic desert and canyon landscapes to stand in for the Asian steppe. Additional scenes were staged in nearby areas of Washington County, while major studio work was conducted back in Los Angeles. The production famously faced significant on-set health incidents due to radioactive dust from nearby nuclear testing, a documented hazard of the era.
Primary Filming Location: Utah
Most outdoor scenes for The Conqueror were shot in Utah, chosen for its wide open spaces and visually striking desert environment that approximated the Mongolian steppes. The production utilized natural terrain features, including canyons, mesas, and dry lake beds, to create the sweeping vistas required for the epic narrative. Specific areas around St. George and surrounding Washington County provided practical backdrops that met the filmmakers' requirements for scale and remoteness.

These sites are situated within a region known for distinctive red rock formations and wide valleys, delivering the stark visual contrasts needed for many sequences in the film.
