Jill Hennessy, Patrick St. Esprit, Ian Bohen and Denim Richards are set for recurring roles opposite Kevin Costner in Yellowstone, Paramount Network’s straight-to-series period drama set to premiere in 2018.

From Oscar-nominated writer/executive producer Taylor Sheridan (Hell Or High Water, Sicario) and the Weinstein Company, Yellowstone follows the Dutton family, led by John Dutton (Costner), who controls the largest contiguous ranch in the United States, under constant attack by those it borders — land developers, an Indian reservation, and America’s first National Park. It is an intense study of a violent world far from media scrutiny — where land grabs make developers billions, and politicians are bought and sold by the world’s largest oil and lumber corporations.
