Taylor Sheridan‘s upcoming Paramount+ series “Land Man” has added four new series regulars, Variety has learned exclusively.

Kayla Wallace (“When Calls The Heart”), frequent Sheridan collaborator James Jordan (“Yellowstone”) Mark Collie (“Nashville”) and Paulina Chávez (“The Expanding Universe of Ashley Garcia”) have all joined the series alongside previously announced lead Billy Bob Thornton and fellow series regulars Ali Larter, Michelle Randolph and Jacob Lofland.

“Land Man” is based on the podcast “Boomtown” and is set in West Texas, specifically the world of oil rigs. The series is officially described as “an upstairs/downstairs story of roughnecks and wildcat billionaires fueling a boom so big, it’s reshaping our climate, our economy and our geopolitics.”

Wallace will play Rebecca Savage, described as “an extremely capable and intimidating liability attorney sent to West Texas to clean up a mess.”

Wallace is repped by Alchemy Entertainment, Play Management, and Goodman Genow.

Jordan will play Dale Bradley, said to be “a petroleum engineer and a blue-collar bear of a man who manages and works with roughnecks in the oil fields. He’s also Tommy Norris’ (Thornton) roommate.”

Jordan is repped by Elevate Entertainment, Artists & Representatives, and Jamie Freed Management.

Collie will play Sheriff Joeberg, described as, aptly enough, “a West Texas sheriff.” Collie is repped by CAA.

Chávez will play Ariana, “a young mother whose family has suffered a misfortune.”

Chávez is repped by Industry Entertainment, CESD Talent Agency, and Felker Toczek.
