Sam Elliott and Garret Dillahunt are headed to Harlan.

They have joined the cast of FX’s modern cowboy drama “Justified” in recurring roles in its upcoming sixth and final season.

Elliott will play Markham, a former Kentucky gangster who returns from exile in Colorado with a fortune earned growing legal marijuana in the state. He comes back to reclaim his former empire and his one-time love, Katherine Hale (Mary Steenburgen).

Dillahunt’s character, Walker, brings special ops and combat zone experience — along with buried demons and simmering rage — to his work as the head of security for a semi-legal businessman. If five seasons of the critically-acclaimed “Justified” are any indication, it stands to reason that Timothy Olyphant’s Raylan Givens will have some part in unearthing those demons and revealing that rage.

The sixth season of “Justified” premiers in January 2015. The show is produced by Sony Pictures Television and FX Productions.
