I think only that they were up at the ranch being interviewed in the early 2000s, beyond that, not sure. I wonder if the "inspired by" true events thing means that it ended up being more fictionalized then they originally intended. It looks decent, it's interesting how the reaction to the CGI varies so much from person to person. We seem to be at the point where you have people who expect it to look utterly real, as if it's just an event that was photographed, and others who recognize it's not real but still find it appealing.
