It appears Marshals is still not done building out its cast.
The Yellowstone spin-off, starring Luke Grimes, who is reprising his role as Kayce Dutton, will finally premiere Sunday, March 1 on CBS.
The Taylor Sheridan-created series features an assembly of both new and returning faces, and though the premiere is already less than a week away, it’s not done introducing new characters in Kayce’s life.
The series has now added Ellyn Jameson to the cast, an up-and-comer known for her stint in Barry, whose credits also include Merv, Law & Order, and the short film Are You Awake?
Little is still known about the recurring role, other than she is named Dolly Weaver, and is the daughter of a rancher.
Her addition however does come after apparent confirmation that Kelsey Asbille, who starred as Kayce’s wife Monica Long Dutton in Yellowstone, is not part of the cast of the spin-off, despite being alive and well in the mothership series’ finale.
It remains unclear what the plans for the character are in the spin-off, however per a logline, in the new series, Kayce has left the Yellowstone Ranch behind him and has joined an elite unit of U.S. Marshals.
He is tasked with bringing range justice to Montana, and balancing his new gig with duties to his family, which the logline only lists as his son Tate (Brecken Merrill) and his confidantes Mo (Mo Brings Plenty) and Thomas Rainwater (Gil Birmingham), who also appeared in the mothership show.
Marshals’ premiere episode is being written by Spencer Hudnut and directed by Greg Yaitanes, and is slated to drop midseason in CBS’ post-Tracker Sunday 9pm time period.
In addition to its stars from the original series and newcomer Ellyn, also joining the spin-off are Logan Marshall-Green as Pete Calvin, Arielle Kebbel, known for Rescue: HI-Surf, Ash Santos, known for Pulse, and Tatanka Means, known for Reservation Dogs, also as series regulars, plus Brett Cullen, who was most recently on Ransom Canyon, under a recurring role.
Executive producer and writer Spencer, speaking to Entertainment Weekly about how Luke’s character will develop, especially as he focuses on both his new gig and fatherhood, seemingly without his wife, shared in December: “He is a cowboy, but he is also a Navy Seal, so he has this incredible toolkit of skills to put to the test.
“He’s a guy who excels running into the fire. As we saw all through Yellowstone, he is really the essence of being a protector, so it felt very natural for him to end up in a position like this where he’s putting others first,” he added.
