Love both movies Oh my god I watched The Hunger Games and Catching Fire before I saw Frozen and when I did see the part where Kristoff says "That is Mahogany" I'm like "OH MY GOD IT'S THE HUNGER GAMES." But I never realized the other similarities.
No, Katniss is the official Mockingjay, Rue inspired the revolution, but Prim started it. If Prim hadn't gotten picked Katniss wouldn't have volunteered then she wouldnt have met Rue who sparked the Mockingjay.
Hunger Games, behind the scenes- I love this film that little bit more than you because I know what a great bond all of the actors ( kids) had - famous and well known actors have told the cats of THG to treasure the experience
