'Horizon: An American Saga': A Cast List for the Upcoming Kevin Costner Western Epic

The first two chapters of the film series release on June 28, 2024 and August 16, 2024

"Horizon: An American Saga" — Kevin Costner's massive, two-part epic that spans 15 years along the American West during the turbulent Civil War era — is finally headed for theaters this summer. And the cast is filled to the brim with award-winning talent.

"Horizon" has been the subject of some controversy over the past year. Costner reportedly shirked his "Yellowstone" commitments to focus on the film, which he co-wrote, produced, directed and stars in. "Yellowstone" co-creator Taylor Sheridan was none too pleased, adding that Costner's untimely departure has affected his character in the series finale.

"I'm disappointed," Sheridan told The Hollywood Reporter last summer. "It truncates the closure of his character. It doesn't alter it, but it truncates it."

"I've never had an issue with Kevin that he and I couldn't work out on the phone," Sheridan continued. "But once lawyers get involved, then people don't get to talk to each other and start saying things that aren't true and attempt to shift blame based on how the press or public seem to be reacting. He took a lot of this on the chin and I don't know that anyone deserves it. His movie seems to be a great priority to him and he wants to shift focus. I sure hope [the movie is] worth it — and that it's a good one."

Whether "Horizon: An American Saga" is indeed a good one remains to be seen. But with this stellar cast involved, all signs point toward an all-time Western classic.
