Kevin Costner's long-awaited Western series "Horizon: An American Saga - Chapter 1" premiered to audiences in 2024. However, due to the first episode not achieving the expected success, the second chapter was shelved after its premiere at the Venice International Film Festival. Warner Bros. had planned for the second chapter to be released in August 2024, but the first chapter only grossed $38 million against a budget of $50 million, putting the project in a difficult position. Additionally, two separate lawsuits related to the production process complicated matters further.

Taylor Sheridan acknowledged that Kevin Costner's departure from the series "Yellowstone" was controversial, but he pointed out that the situation was exaggerated. Sheridan noted that Costner's storyline was initially planned to last three seasons before transitioning to new characters. However, the studio, not wanting to jeopardize the show's success, caused Costner to remain in the series longer than he expected. Ultimately, Costner decided to focus on his own projects, making the "Horizon" series a significant step for him.

The "Horizon" series is a four-part project that Costner partially funded himself. The first episode received mixed reviews from audiences and holds a score of 51% on Rotten Tomatoes. Critics noted that Costner struggled to maintain focus while crafting this expansive story. However, according to FlixPatrol data, the film managed to enter the list of most-watched content on Prime Video this week, which is a promising development for the series' future.

Costner has conducted some filming for the third chapter and is awaiting funding for the fourth chapter. Warner Bros. hopes the first film will find an audience on PVOD and streaming platforms, which would make subsequent chapters financially viable. While the future of the "Horizon" series remains uncertain, Costner's determination and commitment to this project continue to make it intriguing for viewers.
