A flaming costume made Katniss stand out immediately, but Lawrence’s fame took a little more time to develop. First starring in a sitcom and several independent dramas, she found work but little attention until Winter’s Bone came along. At first thought too pretty to play a poor mountain girl, Lawrence finally won over the film’s producers with her natural talent. Her character, Ree, cared for her siblings while searching for their father, a sort of warm-up to playing Katniss.

A secret talent with a bow and arrow helped Katniss win the Hunger Games, and playing Ree won Lawrence an Oscar nomination. Yet she was still mostly unknown to the public until she was offered The Hunger Games role. Like Katniss again, people who thought Lawrence wrong for the part were convinced by her talent and determination. “I have this [protective feeling] over characters I want to play. ... If someone else gets the part, I’m afraid they won’t do it right.” That confidence would also be needed to face a new life in the spotlight.
