Her role as Primrose, the younger sister of Hunger Games star Katniss Everdeen, played by Jennifer Lawrence, has brought her a lot of attention and bodes well for her budding career.
The young wizards of the Harry Potter franchise are the most notable recent example; Willow and her co-stars in The Hunger Games are going to be another set of child actors and actresses growing with and into a series of sequels.
In the sequel Catching Fire, Katniss is at war with the Games authorities, and Prim is growing into the role of family caretaker, patching up the warriors and offering comfort to her older sister, who still burns with righteous anger as leader of the rebellion against the corrupt and vicious regime.
