Award-winning actress Reese Witherspoon is executive-producing the project, which "follows the personal and professional life of Gemma, a ruthless divorce attorney in Dallas, which begins to unravel when her emotionally damaged, love-addicted sister resurfaces triggering self-destructive tendencies and exposing long-hidden family secrets."
Grey's Anatomy star Knight has been cast in the role of Mark, Gemma’s "work nemesis who is competing with her for the same position. On the outside he’s a jolly and likable guy, but really he’s a calculated backstabber you don’t see coming."
Bruna Papandrea is also an executive producer; writer Oppenheimer is a co-executive producer.
Knight made his Broadway debut in the 2001 revival of Noises Off.
