Kevin Costner's anticipated Western film franchise, Horizon: An American Saga, has faced significant setbacks since his departure from the hit series Yellowstone. Although Horizon: An American Saga — Chapter 2 is complete and even premiered at film festivals, it has yet to receive a formal theatrical release. The first installment grossed only $38 million against a substantial production budget of $100 million, leading Warner Bros to remove the sequel from their release schedule. The franchise's struggles are compounded by a lack of audience engagement, raising doubts about its future viability. Meanwhile, Yellowstone has managed to maintain its popularity despite Costner's exit, with viewers still eager to see how the story unfolds. As time passes, the likelihood of Horizon's return to the big screen appears increasingly slim, with many fearing that the saga may never reach its audience. Costner's ambitious project, initially envisioned as a worthy successor to Yellowstone, now risks fading into unfinished ambitions.
