ABC’s freshman hit drama, Big Sky, is adding two new actors this season. According to Deadline, Ted Levine (Monk, On Becoming A God in Central Florida) and Kyle Schmid (The I-Land, Being Human) will join the show in upcoming episodes. The two will play a powerfully wealthy father and son in the David E. Kelley (Big Little Lies, The Undoing) series.

According to Deadline, Levine will join as a series regular portraying Horst Kleinsasser, an old-money rich man whose failing health has him eyeing an heir to the family business. Schmid will recur as John Wayne Kleinsasser, Horst’s youngest son. A traditionalist when it comes to their ranch empire, he is brazen in his attempts to oust his older brother from inheriting the reins of the family fortune.

The series is based on the novel, The Highway, by author C.J. Box (Dark Sky, Long Range), according to Deadline. Kylie Bunbury (Pitch, Under the Dome) and Katheryn Winnick (Vikings, Wu Assassins) star as two investigators, P.I. Cassie Dewell and former officer Jenny Hoyt, searching for a set of kidnapped sisters in the vast of Montana. As they dive deeper into the conspiracy, they learn this isn’t an isolated incident. They must fight time to catch the suspect before he claims another victim. The show also stars Brian Geraghty (Chicago P.D., The Alienist), Jesse James Keitel (Miller and Son, Fluidity), Natalie Alyn Lind (The Gifted, Gotham), Valerie Mahaffey (Jungle 2 Jungle, Dead to Me), Jade Pettyjohn (School of Rock, Little Fires Everywhere) and Dedee Pfeiffer (Cybill, Up Close and Personal).

According to Deadline, the series bolstered such great ratings this fall that ABC extended its episode order to a total of 16. The series is a 20th Television production along with A+E Studios. Kelley and Box are executive producers along with Ross Fineman (Goliath, Lights Out), Matthew Gross (Across the Universe, Body of Proof), Paul McGuigan (Lucky Number Slevin, Wicker Park), and Gwyneth Horder-Payton (The Walking Dead, Tyrant).

New episodes of Big Sky begin January 26 at 10 p.m. ET on ABC.
