Open Range.
I love the way the fight starts out, as the supposedly best shooter in the bad guys' bunch brags about killing the dog, Kevin Costner just walks right up to him and puts a slug into his head, taking off his stove-pipe hat in the process!
From the moment Kevin Costner's character starts walking toward the gun slinger,
it's clear that the gun slinger has misread the situation and is a dead man who
just doesn't know it yet.
Open Range is a favorite of mine for several reasons. Most of the characters are believable,
the dispute is easy to understand, and in the end, the towns people find their back bone
and stand up. In most westerns, the towns people are 'rescued' by the hero, in this case
he just showed them how, and leveled the playing field a bit.

Open Range is probably the most libertarian film I've ever seen, which is quite stunning since its producer/director/star and most of his collaborators are dyed-in-the-wool liberal statists. Some research has revealed that the libertarian-verging-on-anarchist philosophy comes whole from Lauran Paine's novel
The Open Range Men, from which the movie was very closely adapted. Most of the dialogue is lifted verbatim, including Duvall's wonderful speech quoted in my sig. Paine (who, from the 50's until the present day, wrote
hundreds of pulp westerns under 14 pseudonyms!) has become a writer I'm studying and researching: the libertarian/anti-government/anarchist themes play an important role in every book I've located and read by him so far. And it's presented so matter-of-factly and as such an obvious truth that it blindsides the reader (including, apparently, Costner and his pals when they adapted the novel!). In seeking novels to base spec scripts on, it seems Mr. Paine is a treasure trove.

And, beyond that, his books are beautifully written: tough, taut, sleek and realistic, with fantastic dialogue, plenty of humor and characters who manage to be both believable
and heroic. I highly recommend his work to all, and consider it on the level of L'Amour and Leonard.
