I watched "The Only Good Indian" on the Western Channel this evening.
Released in December 2009, the movie was filmed entirely in Kansas except for one scene in Missouri. It was partly filmed in Chautauqua County at the Red Buffalo Ranch, probably at the falls featured in one of the scenes.
The movie features a very complicated plot related to Indian vs White Man culture. Other than the Sundance Movie Festival and the American Indian Film Festival, it does not seem to have gotten very far, but I enjoyed watching it.
