Kevin Costner's Horizon: An American Saga failed where his neo-western Yellowstone succeeded despite having similar structures and genres.

Kevin Costner's magnum opus Horizon: An American Saga appears to be in limbo after the first chapter of the four-part film bombed at the box office. Costner directed and financed the films himself, selling some of his property to finance the $100 million budget. The first film, which was released in June, only managed to earn $36 million.

Costner's directing reportedly came at the expense of his successful neo-Western TV show Yellowstone, which he left after clashes with creator Taylor Sheridan and the studio. While Costner has been a master of the western genre, he seems to have fumbled with Horizon where Yellowstone succeeded.

Kevin Costner received his Oscar for Best Director for his directorial debut Dances with Wolves, which is considered to have revived the western genre in Hollywood. It is only the fourth Western in Oscar history to win the Oscar for Best Picture, with Unforgiven and No Country For Old Men following it.
