Martindale, 59, will play Mags Bennett, a towering figure in the Harlan County criminal world. She's the matriarch of the Bennett clan, which has had a Hatfield and McCoys-type relationship with Raylan Givens (Timothy Olyphant) and his family for years.

The Bennetts have been the biggest pot farmers in Eastern Kentucky for generations, and they were bootleggers before that. Mags is described as a defender of the old ways, and even at her age, she's more dangerous than ever. As you can see in this exclusive first look at Season 2, that will quickly put her in Raylan's line of fire.

Martindale's casting follows that of Lost's Jeremy Davies, who will play Mags' oldest son, Dickie, who was a high school rival of Raylan's. Dickie still walks with a limp because of an altercation with Raylan on the baseball field when they were both 17.

Martindale is slated to recur in the second season. Her recent small-screen credits include stints on Mercy, Dexter and The Riches.

Based on an Elmore Leonard short story, Justified follows trigger-happy U.S. Marshal Raylan Givens as he navigates old ghosts — his ex-wife (Natalie Zea) and childhood best friend-turned-nemesis (Walton Goggins) — when he is assigned to his hometown. The show averaged 3.6 million viewers in its first season. Season 2 is scheduled to premiere sometime in February.
