SINSULL - The banjo playing scene is another film, one that is yet to be released and I hope the scene makes it to the film, but who knows. It's another film company and I don't where they stand in the production process.

Yes - SC, the film does cover the history behind the story. It is actually a documentary with a few dramatic reenactments, like you saw in the trailer. There exists a lot of documentation from the period.
