No one said no to John Wayne at the top of his game, not even Howard Hughes. That is why Wayne ended up completely miscast in the worst movie of his career, and one of the worst movies of all time according to various polls. When the script for this epic about Mongol leader Genghis Khan started making the rounds in Hollywood in the mid-1950s, everyone’s favorite cowboy thought he’d be perfect for the decidedly Asian titular role. Sadly, no one else agreed, but apparently didn’t think to say anything until after the picture was made. As the film’s producer, Hughes was so mortified by the results that he reportedly bought every print at a cost of $12 million just so no one could show it in theatres again.
