In 2021, Kevin Costner took interest in a different Yellowstone than the television series he’s worked on for the past six years.

Marc Pierce, executive producer and CEO of Montana-based Warm Springs Productions, went to Costner with a pitch to be the narrator and host of “Yellowstone One-Fifty,” a four-part series told from the historical perspective of the 1871 expedition led by geologist Ferdinand V. Hayden to explore the region.
