Jennifer Lawrence (Katniss Everdeen), Josh Hutcherson (Peeta Mellark), and Liam Hemsworth (Gale Hawthorne) are on board, along with Philip Seymour Hoffman, who makes his debut in The Hunger Games: Catching Fire as Plutarch Heavensbee. In Suzanne Collins' novel, Alma Coin is in charge of the district which fights against the Capitol regime, although she doesn't completely trust Katniss.
The Hunger Games: Catching Fire director Francis Lawrence is on board to direct both The Hunger Games: Mockingjay Part 1 and The Hunger Games: Mockingjay Part 2, from an adapted screenplay by Danny Strong. It isn't known when production will begin.
Julianne Moore will next be seen in Don Jon, Carrie, and The Seventh Son, all hitting theaters on October 18.
