Let it never be doubted that American popular culture has conquered the world. Remember that the Western motif was essentially American morality tales.
No other movie genre like it or ever will be.
High Noon was a tale crafted about Hollywood's persecution of communists in cinema. Gary Cooper represented the ethical, good hearted communist being outgunned by the McCarthy types.
Rio Bravo was made in response to High Noon. Rio Bravo depicted the good guys (those who were fighting communism) against the evildoers in Hollywood.
I used to like Gary Cooper until I read about what a philanderer he was and how he used to beat his mistress, Patricia Neal. (Also a favorite actress of mine.)
