Juliette Lewis and Callum Keith Rennie are signed on to star in NBC’s new legal drama series “The Firm,” based on John Grisham’s best-selling novel and executive-produced by Grisham and Lukas Reiter.

Lewis and Rennie join Josh Lucas who was previously announced to star as attorney Mitchell McDeere (the role originated by Tom Cruise in the film). The pilot episode will commence production in Toronto this August.

Lewis, am Oscar, Golden Globe and Emmy Award nominated actress, will play Tammy, Mitch’s feisty, sexy receptionist, whose work life is made all the more tumultuous by her on-again, off-again relationship with Mitch’s brother, Ray. With a personality as arresting as her ever-changing hair color, Tammy is leery when Mitch accepts a deal to partner with a top law practice, as she’s not cut out for the conservative culture of a white shoe firm.

Based on the blockbuster feature film and the best-selling novel of 1991 by world-renowned author Grisham (“The Pelican Brief,” “The Client”), “The Firm” continues the story of attorney Mitchell McDeere (Lucas) who, as a young associate, brought down the prestigious Memphis law firm of Bendini, Lambert & Locke, which operated as a front for the Chicago mob. After a difficult decade, McDeere and his family now emerge from isolation to reclaim their lives and their future — only to find that past dangers are still lurking and new threats are everywhere.
