NBC, Entertainment One, Sony Pictures Television Networks and Global Television confirmed the casting news Friday.
Parker is to play Abby McDeere in the network's small-screen adaptation of John Grisham's best-selling novel, which is being executive-produced by Grisham and Lukas Reiter.
"Ten years ago, Abby helped her husband Mitchell McDeere bring down a Memphis law firm that was a front for the Chicago mob. Her life was never the same," NBC said in a synopsis. "Abby's a true partner to Mitch -- a smart, resourceful woman who after a tumultuous decade is excited to start a new life in Washington, D.C., as a school teacher."
Parker, who is known for her work in TV's "Deadwood" and "Swingtown," joins a previously announced cast including Josh Lucas as Mitch; Juliette Lewis as Tammy, who is now Mitch's receptionist; and Callum Keith Rennie as Ray McDeere, Mitch's charming yet volatile older brother, NBC said.
