Kevin Costner's highly anticipated film, "Horizon: An American Saga - Chapter One," opened in over 4,000 theaters across North America last weekend. However, despite Costner's star power and the success of his hit TV series "Yellowstone," the movie failed to make a significant impact at the box office.

With a production cost of $100 million, "Horizon: An American Saga - Chapter One" opened to a disappointing start, earning just $11 million in its debut weekend. This lackluster performance drew comparisons to successful films like "A Quiet Place: Day One," which attracted 3.6 million viewers, and "Inside Out 2," which recorded 5 million viewers during their respective opening weekends.

The film's underwhelming response has raised concerns in Hollywood about the upcoming release of "Horizon: An American Saga - Chapter Two," which is scheduled to hit theaters in just six weeks, on August 16. Despite these concerns, there are currently no plans to change the release date for the film.

Industry insiders and exhibition executives are hesitant to declare "Horizon: An American Saga - Chapter One" a box office failure just yet. They believe that the film still has potential to find its audience over time. Costner, known for his confidence, had taken on the ambitious project of directing and starring in four "Horizon" movies, with Warner Bros. signing on as the distributor.

The film's target audience was expected to be older viewers, similar to the demographic of Costner's successful TV series, "Yellowstone." However, exit surveys conducted by PostTrak revealed that over 60 percent of ticket buyers were aged 45 and above, with 47 percent aged over 55. Only a small portion of ticket buyers, 11 percent, fell into the 18-24 age range.

Costner and Warner Bros. had hoped that "Horizon: An American Saga - Chapter One" would resonate with viewers, especially in America's heartland, just like "Yellowstone" has. However, the film failed to garner the desired level of support and enthusiasm from fans.

As of now, the financial success of "Horizon: An American Saga - Chapter One" relies heavily on its performance in premium Video On Demand (VOD) and other home entertainment platforms. Analysts suggest that the film's appeal to older demographics could potentially boost its chances in these formats.

While the disappointing box office numbers for "Horizon: An American Saga - Chapter One" raise questions about the future of the third and fourth installments of the franchise, which are not part of the distribution deal with Warner Bros., Costner remains determined. He has already shot a few days for the third film and will resume production in August, but additional financing will be required to complete it.

Despite the initial performance of "Horizon: An American Saga - Chapter One," Costner remains positive and encourages fans to look beyond the opening weekend gross. He emphasizes that the film's long-lasting impact is what truly matters to him.

Internationally, "Horizon: An American Saga - Chapter One" made its world premiere at the Cannes Film Festival and plans to expand its reach overseas. However, specific numbers or data regarding its performance in those markets have not been reported yet.

As audiences and industry professionals wait to see how "Horizon: An American Saga - Chapter One" progresses, all eyes are on whether the film can overcome its slow start and find success in the long run.
