Actors Jennifer Lawrence, Josh Hutcherson and Willow Shields are the stars of the blockbuster film franchise “The Hunger Games. And for them, exploring a new exhibition about the world depicted in the movies was like taking a trip down memory lane. “The Hunger Games: The Exhibition” has hundreds of costumes, props, photos and interactive displays. It opened on Wednesday at the Discovery Times Square museum in New York City. The exhibition brings fans into the dystopian, post-apocalyptic nation of Panem depicted in the films. 24-year-old Lawrence plays the feisty teenage heroine Katniss Everdeen in the action-packed survival films. She said of the exhibition, “It was really emotional. I didn’t expect that. There’s a lot of stuff I’d like to keep.” The final film, “The Hunger Games: Mockingjay – Part 2,” is due to be released on Nov. 20th.
