Horizon Chapter 1’s Theatrical Release & What Went Wrong
The Movie Underwhelmed At The Box Office
Expectations were high at one point forHorizon: An American Saga - Chapter 1’s theatrical release and how it could perform at the box office.

The troubles forHorizon’s box officecame from a multitude of places. It did not help thatCostner’s movie received mostly negative reviews from critics, driving its Rotten Tomatoes score down to 48%. Audiences were reasonably mixed on the 3-hour-plus epic, giving it a 70% rating on the Popcornmeter. Westerns already have difficulty finding an audience in theaters nowadays, as they are not the dominant movie genre like before. Without having a strong word of mouth behind it,Horizon: An American Saga - Chapter 1couldn’t find much traction.
The extensive franchise plans forHorizon: An American Sagamight have also turned away some viewers. The sequel was planned to come out only a few weeks later, but Warner Bros. reversed that decision after seeing how poorlyChapter 1did at the box office. Still, the movie’s title tells audiences that this is not a standalone story, and Costner very much treats the movie like the introduction to a larger narrative.
Horizon: An American Saga - Chapter 1’s Streaming Release Could Help The Sequels
It Already Did Well On PVOD
With so much uncertainty about the fate ofHorizon: An American Saga’s sequels, the streaming release forChapter 1could be a pivotal moment for Kevin Costner’s franchise and its future. The movie’s potentially massivesuccess as a streaming movie on Max could be enough to help convince Warner Bros. to let Costner finish making the third and fourth installmentsthat are currently in need of more financing. TheHorizon: An American Saga’s sequels could even be made directly for streaming ifChapter 1proves to be a big enough hit for Warner Bros.’s streaming service.
There is reason to believe this will happen too.Horizon: An American Saga - Chapter 1already dominated VOD chartsafter its release. That shows that there is interest in Costner’s films, just not as a big-screen movie franchise. Any significant impact thatHorizon: An American Saga - Chapter 1makes on Max as a streaming release is good news for Kevin Costner, especially when it comes to getting a new release date forChapter 2. If the opposite happens, the chances of these sequels happening continue to drop.
