Kevin Costner's ambitious film series, 'Horizon: An American Saga,' debuted on June 28 but has faced significant challenges, grossing only $32 million against a $100 million budget, leading to its classification as a box office flop. Despite a standing ovation at Cannes, critics have largely dismissed the film, and the second installment was pulled from its scheduled release. Costner, who invested $38 million of his own money into the project, remains optimistic, believing that the film's true value will be recognized over time, similar to his earlier success with 'Dances With Wolves.' The first chapter has been described as setting up a larger narrative across four planned films, which has left some audiences feeling unsatisfied. The second film is expected to screen at the Venice Film Festival, but a new release date for theaters has not yet been determined. Costner emphasizes the historical significance of the story, which reflects on American migration and Native American experiences, hoping it will resonate with viewers in the long run.
