Yellowstone, a sprawling neo-Western set in the arresting expanse of Montana, is famously a ratings juggernaut—season four’s finale on January 2 beat season three’s viewership numbers by 81%. But it also has a number of firsts under its cowboy belt buckle. It was the first scripted series for the newly formed Paramount Network, rebranded from Spike TV and launched in 2018. It’s the first writing venture into television for cocreator Taylor Sheridan, who’d already impressed critics with films Sicario, Hell or High Water, and Wind River. It marks Kevin Costner’s first regular returning appearance on a TV series, in the lead role as cattle ranch patriarch John Dutton. And now, the show’s family drama about century-old land grabs, greedy developers, cowboy life, and a Native American community fighting for its future—plus a steady clip of harshly doled-out street justice and comically rough brawls—has its first Screen Actors Guild Award nomination, for drama series ensemble.
