The Conqueror

In the historical epic The Conqueror, John Wayne stars as Temujin, better known as Genghis Khan. Red-haired Susan Hayward costars as Bortai, the Tartar princess whom Temujin claims as the spoils of battle. Eventually, Bortai's hatred for her captor metamorphoses into love, while Temujin's hordes lay claim to the entire Gobi Desert. Director Dick Powell, many of the actors (John Wayne, Susan Hayward, Pedro Armendariz, Thomas Gomez, Agnes Moorehead), and several of the crew members later fell victim to cancer, allegedly the result of producer Howard Hughes' decision to lens the film on location near the atomic testing grounds in the Utah desert.
