The Yellowstone prequel is in the works, and we’ll finally discover how the Dutton family got its start!

According to a February 5 press release from Paramount Network, “Y: 1883 follows the Dutton family as they embark on a journey west through the Great Plains toward the last bastion of untamed America. It is a stark retelling of Western expansion, and an intense study of one family fleeing poverty to seek a better future in America’s promised land—Montana.”

Taylor Sheridan, the show’s creator, said in a video posted on Twitter, “I was always fascinated when I came up with the story of ‘Yellowstone’ about how do we make it bigger and expand it. This new show explores different eras of that 130-year legacy.

Who is in the Y:1883 cast?

Sam Elliott as Shea Brennan

“Sam Elliott will be integral to the Yellowstone prequel in the role of Shea Brennan, a brick-tough cowboy who doesn’t take shit from anyone, especially when the stakes are high, as it goes during a wagon-train trek from Texas to Montana. Shea will be the guide for that group, which includes the Dutton family ancestors mentioned lower, but viewers can also expect to see the character suffering intense sadness due to an unknown incident in his past.”

Tim McGraw as James Dutton

“For 1883, Tim McGraw will take on some hefty familial baggage in portraying James Dutton, the great-grandfather of Kevin Costner’s John Dutton. Details are light at this point when it comes to James’ personality and, well, everything else, but McGraw himself has taken to sharing social media posts with set details that fans can glean info from. For instance, it looks like James might be something of a gunfighter.”

Faith Hill as Margaret Dutton

“Within the world of 1883, we know that Faith Hill will portray Margaret Dutton, wife of James and great-grandmother of John Dutton. Unfortunately, we don’t even have very many social media posts to theorize about when it comes to Margaret’s character or her motivations. One can only assume, however, that anyone whose lineage leads to Kelly Reilly’s Beth Dutton has fire and brimstone running through her veins.”

Isabel May as Elsa Dutton

“Isabel May will take on the role of Elsa Dutton, the eldest daughter within that traveling Dutton clan at the heart of 1883. It can be assumed that she’ll serve as John Dutton’s grandmother, though that could technically be disproven if other casting announcements reveal Elsa has a sister.”

LaMonica Garrett as Thomas

“Expect to see another leadership-geared performance from LaMonica Garrett in 1883 as Thomas, who is both a Pinkerton agent on the grand scale, and a right-hand man to Sam Elliott’s Shea Brennan on a small scale. It should be interesting to see how the racial politics play out for his role, given the time frame and the character’s multiple points of authority.”

Billy Bob Thornton as Jim Courtright

“Billy Bob Thornton won’t be around 1883 for the long haul, as he’ll be showing up in a guest-starring capacity for the role of Marshal Jim Courtright. That’s about all the info there is for the role, so it’s not entirely clear if Courtright is located in Texas or elsewhere, nor how long audiences can expect to see him. Though if the prequel series is meant to cross most of the country in order to get to their eventual family ranch in Montana, there isn’t much time for the characters to stick around and meet new people.”

Talk about a blockbuster cast! The Paramount+ Instagram page confirmed that the new show will premiere on December 19. Stay tuned for more updates!
