According to Variety, Leo will play a civil rights attorney, joining Clarke Peters, Wendell Pierce and Steve Zahn in the pilot, which will be directed by Agnieszka Holland.
Leo earned her first Oscar nomination, and won a Spirit Award, for her role in "Frozen River." No stranger to the small screen, Leo's TV credits include "The Young Riders," "Law & Order" and "Homicide: Life on the Street" (based on Simon's book).
