John Wayne, the greatest war hero to never serve. He got rich making movies while other men died. When aliens take over earth, if they only watch the movies, they will not know what John Wayne's good friend and director told him.
John Ford:
Thirteen wartime movies later, and the flag of heroism he rose in the said Sands was still awaiting his recruitment in real-life. And this was a fact that John Ford, now a commander in the U.S. Navy, never shied away from letting the Duke know about. He would frequently berate Wayne "to get into it," saying that he was growing rich as other men died.
Compare Henry Fonda:
Wayne (born Marion Morrison) was also concerned that the war would age him out of high playing action roles once the fighting finally ended. Henry Fonda, on the other hand, paused his paychecks and wasn't looking for theater in the global drama that was playing out across the world. "I didn't want to fight a fake war in a studio," declared the well-known Hollywood liberal.
