20. John Wayne – Genghis Khan
Overall, the Conqueror performed poorly since John Wayne was from Iowa and Mr. Khan was from Asia. While Wayne had done well in the west, he desired a change. Howard Hughes wanted him to be a part of this cast, but everything went wrong.

21. Scarlett Johansson – Major Mira Killian
While Johansson’s acting is excellent, the casting director made a mistake by casting a white actor in an Asian role. Ghost in the Shell was a piece of anime history, and the lead role should have gone to a lesser-known actor. However, Hollywood insisted on having someone “famous,” which destroyed the whole deal.
