In a May 2023 Instagram post, director Costner said he hasn’t felt this way about a movie since making the Oscar-winning blockbuster “Dances with Wolves.” In an interview with Deadline in June 2023, he said: He had been developing the series in various forms since 1988, but had difficulty “finding people to do it.” Instead, he took out a mortgage on his 10-acre home in Santa Barbara, Calif., and partially financed the project himself, he said at the time.

Costner said in November 2022 that Hayes, his 14-year-old son with ex-wife Christine Baumgartner, would appear in the film. At the time, he joked that the film’s script had “been around longer” than Hayes’ life.
