"The Hunger Games" movie release countdown is officially on! If you don't know the premise of the story, it's basically twenty-four adolescents (called Tributes) who fight in a televised battle to the death until only one person is left! (Which is totally comparable to "Battle Royale.") By now, you should know that Jennifer Lawrence, Josh Hutcherson, and Liam Hemsworth have been cast as the lead characters Katniss Everdeen, Peeta Mellark, and Gale Hawthorne, respectively. Here's all the info you need on the "Hunger Games" kids.
