Based on John Grisham’s best-selling novel but set 10 years later, the midseason drama finds Josh Lucas succeeding Tom Cruise as attorney Mitch McDeere. The series picks up with Mitch and wife Abby (Molly Parker) trying to start a new life in Washington D.C.
Helfer plays Alex Clark, the senior partner of Kinross & Clark, who brings Mitch in as a partner.
“[I’ll] be working with some amazing talent,” Helfer posted on Twitter late Saturday. “[I’m] very excited!”
The Firm‘s cast also includes Juliette Lewis as Tammy, Mitch’s feisty receptionist, and Helfer’s former BSG co-star Callum Keith Rennie as Ray McDeere, Mitch’s volatile older brother.
Production is currently underway in Toronto.
