Kevin Costner finally has a replacement for his role as John Dutton III in Yellowstone, and the new Western show continues one of the actor’s longest career trends. Since Kevin Costner left Yellowstone midway through season 5, many fans have been wondering if he can find a replacement for Taylor Sheridan’s wildly successful Western series. Costner has tried to find his own replacement through Horizon: An American Saga, but that effort fell short.

Now, Costner has another upcoming Western project that not only serves as a Yellowstone replacement, but also as proof that he’s sticking with one of his oldest trends as a movie maker. Costner is producing The Gray House, a Western series for Prime Video. While he won’t be acting in The Gray House, Costner’s upcoming show is still worth learning about, and it reveals an important fact about the future of his career.

What Is The Gray House About?

Kevin Costner is set to co-produce (alongside Morgan Freeman) Prime Video’s upcoming Western TV show The Gray House, which is set to premiere on February 26, 2026. Early images of The Gray House reveal that the show is based on a real group of women who were involved in both the Underground Railroad and a spy ring that gave Confederate secrets to the Union and helped “turn the tide” of the Civil War (via Deadline).
