Katniss Everdeen (Jennifer Lawrence) and Peeta Mellark (Josh Hutcherson)
''These are kids growing up in war who physically, emotionally can't love somebody,'' says Jennifer Lawrence about the uncomfortable triangle between District 12's battle-weary Katniss, Peeta, and her childhood friend Gale that began in The Hunger Games. ''Katniss thinks she can't have a crush on a boy because she's worried about survival every single day. And she can't be a normal 16-year-old meeting her friend out in the woods and practicing kissing because that's not the world that they live in.''
