The Hunger Games franchise director Francis Lawrence addresses the controversial decision to divide the adaptation of the final novel Mockingjay into two movies. Suzanne Collins' 2010 novel served as the conclusion to the initial Hunger Games trilogy, following former games Victor Katniss Everdeen (Jennifer Lawrence) as war breaks out across Panem, where she grapples with being a figurehead of the resistance against the Capitol. The novel's movie adaptation was divided into two parts, released on November 21, 2014, and November 20, 2015, respectively.
