High Noon's plot can be seen as an allegory for McCarthyism and the Red Scare. The writer
, a former Communist party member, refused to name names.
[High Noon is] the most un-American thing I’ve ever seen in my whole life. - John Wayne.
John Wayne supported blacklisting and disliked the anti-Red Scare theme of the film.
I made Rio Bravo because I didn't like High Noon. Neither did Duke (John Wayne). I didn't think a good town marshal was going to run around town like a chicken with his head cut off asking everyone to help. And who saves him? His Quaker wife. That isn't my idea of a good Western. - Howard Hawks
