  • Luke Grimes will reprise his role as Kayce Dutton after initially believing the character’s story had concluded with Yellowstone’s finale.
  • The spin-off’s premise follows Kayce using his cowboy heritage and Navy SEAL training to enforce justice across Montana as a U.S. marshal.
  • Premiere timing remains uncertain, with reports pointing to either a late-2025 debut or a spring 2026 launch.
  • No other cast members have been confirmed so far, although familiar Yellowstone faces are rumored to return.
