In the bestselling novel by Suzanne Collins, Alma Coin is the leader of the rebellion against the wealthy Capitol and tyrannical President Snow. Though she's at the front of Panem's justifiable uprising against the ruling power, Coin is also ruthlessly manipulative, and her efforts to exploit Katniss Everdeen's symbolic status suggest that perhaps Coin's motive aren't exactly altruistic.
In Mockingjay, Jennifer Lawrence will return to play Katniss, along with Josh Hutcherson as Peeta Mellark, Liam Hemsworth as Gale Hawthorne, Donald Sutherland as President Snow, Philip Seymour Hoffman as Plutarch Heavensbee, and a whole bunch of others.
And, according to Deadline, Moore is the top choice to join the series as Alma Coin.
Though her negotiations with Lionsgate have yet to commence, things are expected to move pretty quickly on the casting. That's because everything on The Hunger Games is moving quickly at this point. The distributor long ago announced consecutive annual release dates for Catching Fire and both Mockingjay installments. Gary Ross, the first film's director and co-writer, exited the franchise over concerns about meeting the November 22, 2013 Catching Fire release date.
Constantine, I Am Legend, and Water for Elephants director Francis Lawrence takes over on the sequel, and he's set to carry on for the duration of the series. So even as he's in post-production on the first sequel, the director is in pre-production on the third and fourth so that they can be in theaters on November 21, 2014 and November 20, 2015.
Four-time Academy Award nominee Moore has quite a lot going on in the near future. This September, she plays a crucial supporting role in Joseph Gordon-Levitt's directorial debut Don Jon. In October, she plays crazed, fundamentalist mother to Chloe Grace Moretz in the Carrie remake and also goes up against Jeff Bridges in the fantasy adventure Seventh Son.
Coincidentally, both parts of The Hunger Games: Mockingjay are currently being written by Danny Strong, who also wrote the HBO movie Game Change. Moore won an Emmy and a Golden Globe for her portrayal of Sarah Palin in the telemovie.
