In some ways, High Noon attacks the pacifism of Grace Kelly's character as a Quaker. For, she wants Gary Cooper's character to wash his hands of the old conflict and forget about being the marshal to just be her bridegroom. However, she understands finally that defending her husband takes precedence over her impractical religious beliefs.
That she can assert herself and defend her husband when the people who owe him their safety do not, bespeaks of what is certainly "unAmerican" in the days of the Old West. The breed of men who populated the western towns in the nineteen hundreds were courageous, not pusillanimous as they are portrayed. At any rate there is no real comparison between the stock character of a Western and the screenwriters, producers, actors of Hollywood. This is why John Wayne disliked the film; it lacked verisimilitude. The meek Quaker girl becomes stronger than the Western men who must have fought off others who would exploit their town. While all the townspeople may not have come to Marshal Kane's assistance, there would be some who certainly would.
While the film does possess some universality, it has a large Western credibility gap.
