The Conqueror

"When you think of Genghis Khan (Mongolian, conqueror of half the known world, shrewd military tactician, Mongolian, mass murderer, Mongolian, vengeful, Mongolian) who do you picture? John Wayne, right? Exactly. And that's why he was an inspired casting choice for Howard Hughes' 1956 epic The Conqueror. Speaking before the film was made, Wayne said 'the way the screenplay reads it's a cowboy picture, and that's how I'm going to play Genghis Khan. I see him as a gunfighter.'"
