Dances with Wolves is one of the more important films on my 250th anniversary watchlist. While movies sympathetic to American Indians had been made, it had never been done on such a scale, and certainly had not drawn as much commercial and critical success. This came as a surprise because everyone thought the director and actor, Kevin Costner, was wasting his time on a guaranteed failure. He literally spent five years of his life trying to get the movie made, turning down major movie roles while he sank his own money into the project. It was seen as a vanity project doomed to fail. Instead it was a vanity project that succeeded.
The movie is said to be based on a novel by Michael Blake, but actually the novel originated as a screenplay by the same author. It was turned into a book so that Costner could have better luck attracting support for his film. That being said, there is a stark difference. The novel is set in the American Southwest with the Comanches, but it turned out they couldn’t get enough buffalo in that region to film, so the location was turned to the northern Great Plains with the Lakota Sioux. However, there’s a scene where an old Indian holds up a conquistador helmet to explain previous European incursions. This is an obvious holdover from the earlier script and novel, as 15th-16th Century Spaniards never clashed and likely never even met the Sioux.
