4. It's a fight to the death, but it's also a love story.
Katniss is chosen to represent District 12 along with Peeta Mellark, played by Josh Hutcherson, who is a mere acquaintance but one she remembers as having a kind heart. (The son of the local bread maker, he gave scraps to Katniss and her sister when they needed them most). As they head into the unknown together, there's an undeniable chemistry, and after Peeta reveals he has feelings for Katniss in front of the cameras, the two play up that angle to the delight of Capitol's citizens.
But there's also the boy she left behind – her best friend and hunting buddy -- Gale Hawthorne, played by Liam Hemsworth. Gale promises to take care of her family no matter what happens when she goes into the arena. Despite the Tracker Jackers (genetically engineered wasps that can sting to death) and other obstacles in the arena, it's Gale she can't get out of her head.
5. It could be bigger than "Twilight."
The "Hunger Games" triology could be as big as "Twilight" and may even reach the level of "Harry Potter," experts say. There is already "Hunger Games" paraphernalia, from "Teem Peeta vs. Teem Gale" T-shirts to cookbooks, action figures, even an exercise workout and nail polish line. With over $100 million in ticket sales expected for the first weekend alone, only time will tell how the franchise will play out in pop culture.
