Jennifer Lawrence is ruling herself out of starring in a prequel to the Hunger Games franchise, insisting it is ?too soon? to expand the movie series. The Silver Linings Playbook actress starred as Katniss Everdeen in four films, based on three books by Suzanne Collins, and the franchise came to a close with the Hunger Games: Mockingjay ? Part 2 , which was released in November. Although the source material has now run out, Lionsgate vice chairman Michael Burns recently hinted studio bosses would be exploring new storylines, including a project based on Katniss? backstory.
