Kevin Costner’s ‘Horizon’ Is Debuting Friday. Will Audiences Follow?

Oh, to have the self-confidence of Kevin Costner.

There are few actors in the final chapter of their career who would turn down a consistent $1 million-an-episode payday to pursue the vagaries of the Wild West. Yet there are few actors who are as single-minded as Costner.

For the 69-year old star and director, who has made a career of taking the road less traveled, has embarked on what many would call a foolhardy quest to turn his long-percolating story of the settling of the West post-Civil War into four theatrical films. It’s an endeavor he’s undertaking without the true support of Hollywood: No legacy studio wanted to finance his sprawling epic. And it’s one that comes at great personal cost, both financially, with Costner investing $38 million of his own money, and professionally, with his commitment to the films causing a schism with the producers of “Yellowstone,” the television franchise that revitalized his career.

There is no guarantee his grand experiment will succeed. “Horizon: An American Saga — Chapter 1” is set to debut Friday. And in an unprecedented move, “Chapter 2” will hit theaters less than two months later, on Aug. 16. Both features cost in the $100 million range. Warner Bros. is releasing the films in the United States, Canada and some international territories in a service deal calling for Costner to pay for the marketing costs while collaborating with the studio on the creation of the marketing materials. (Warner Bros., according to a representative who was not permitted to speak on the record, has a small financial stake in the production of the first two films.) The deal’s structure means that should the movies backfire, there will be little financial downside for the studio but much risk for Costner himself.

But as he has put it, letting go was never an option. He first commissioned the script back in 1988. He almost made it with Disney, but the two parties couldn’t agree on a budget and the movie didn’t go forward. Then, instead of retooling one movie to fit the parameters of potential buyers, he and the screenwriter Jon Baird turned it into four. To partly finance the films, he mortgaged a 10-acre piece of undeveloped coastline in Santa Barbara that he’s owned since 2006.

“It’s hard to fall out of love for me. I don’t do that,” he told journalists during the online debut of his teaser trailer in February, and added, “There’s a lot of people out there that know I’m a little bit of a hard-head or something. When no one wanted to make the first one, I got the bright idea to make four. So I don’t know what’s wrong with me.” (Costner declined to be interviewed for this story.)
