Kevin Costner, known for his roles in successful series like Yellowstone and films like Molly's Game, faced a setback with his recent project 'Horizon: An American Saga - Chapter 1,' a western film he directed, co-wrote, and starred in. Despite investing $38 million of his own money into the $100 million budget production, the film only grossed $11 million in its opening weekend, raising concerns about its financial success. While Costner remains dedicated to the project, critics have been harsh, with poor reviews citing the film's lack of excitement. The second part of the series is set for release on August 16, adding pressure for a better performance and cost recovery in the future.
