Kevin Costner made a directing return after 20 years to film and star in his passion project Horizon.

With Chapter Two already filmed and expected to premiere sometime this year, Costner gives an exciting update for Horizon: Chapter Three and Chapter Four.

As the trailer of Horizon: An American Saga showed the film’s massive wide-open scale, you can tell that Kevin Costner poured everything into giving audiences a Western film that’s both visually appealing and entertaining for audiences. Unfortunately, the 2024 movie release gave critics mixed feelings and a disappointing opening weekend of $34.3 million on a budget of $50 million.

I made a promise to myself, I'm trying desperately to keep it, and to bring it to people, these kind of giant stories, and I hope that people fall in love with these characters. While Horizon: Chapter Two lost its August 16th release date after Chapter One underperformed at the box office, it’ll still have its premiere at .
