Not too nitpick but it's TRACY.
I think this is a better film then High Noon which I actually rewatched earlier today. The films have a similar theme (both movies were written with the blacklist as the very deliberate subtext) but transmitted to the setting of the Western the story Carl Foreman wrote translated horribly in context of the western which was about settling the frontier which took courage. Foreman uses the metaphor to such an extent that later critics (including notably Roger Ebert) realized how heavy handed it was and that it may have succeeded at the time more because of the technical aspects than the screenplay.
In that sense calling Bad Day a western is a better idea because by being set in the 1950s and dealing with the greater truths by Tracy's work, it truly resonates. I suspect tthat when Edward Zwick made the undervalued film Courage Under Fire - which also deals with the posthumous receipt of a medal abd the hostility by those who know the truth - he had Black Rock in mind. The fact that it actually was willing to deal with a subject that was very fresh in the memories of moviegoers in 1955 shows a bravery that impresses me about all involved. Tracy was always an actor who was willing to give gutsy performances about quiet courage as was best portrayed in his work with Stanley Kramer in the 1960s (Inherit the Wind, Judgement at Nuremberg and Guess Who's Coming to Dinner are all masterpieces in that regard - Tracy deservedly was nominated for Best Actor for all three movies along with this one.)
I can have my own discussions of how many recent films are Westerns. I don't think anyone would argue if I were to call Hell and High Water one.
