The three directors about whom the most has been written in scholarly journals over the years are Howard Hawks, Alfred Hitchcock, and John Ford. Frank Capra and D.W. Griffith have received almost as much attention in the academy but that's merely interesting to note, not particularly relevant. To my way of thinking, Hawks cut the finest gems. Personally, I don't see libertarianism as being inherently anti-state the way so many comments on this page do. Libertarianism isn't the same as anarchism.
Limited government is necessary to foster civilization.
Rather, I see libertarianism as the belief in individual rights and freedom. Ok, a few other Hawks movies worth watching. It's also one of the movies I like to use to support my argument that John Wayne is one of the finest screen actors we've ever known. I'll get to that some other time if anyone asks me to. Triumph of human ingenuity over nature.
