The Conqueror is a 1956 American historical drama film directed by Dick Powell. It stars John Wayne as Genghis Khan, a casting choice widely criticized for its whitewashing. The film is infamous not only for its poor critical reception and box office failure but also for the tragic health consequences faced by its cast and crew, many of whom developed cancer due to filming near a nuclear test site in the Nevada desert.
It might have been that Genghaskhan movie. Was it the Genghask Khan movie?
