Just as she did in the novels, Katniss Everdeen, played by Jennifer Lawrence, sported an ornate braid to manage her long, brown hair, and she had that so-called "Seam look" of olive-toned skin, dark straight hair, and humble clothing indicative of her life in one of Panem's less favored districts. One of the more obvious differences when it came to her appearance, though, was the fact that she wasn't quite as short or gaunt as the Girl on Fire.
There were other minor deviations, like the fact that her hunting jacket from the Seam was a little more fitted than fans might've expected from a hand-me-down from her late father, and her eyes sometimes seemed a little more green or blue than gray most of the time. The most egregious error in translation, however, was her age. Lawrence was in her early 20s when she took on the role of the 16-year-old protagonist, but many fans were willing to overlook the adaptive aging process there if it meant nabbing the eventual Oscar winner for the part.
In Katniss' eyes: Almost all of the boys and at least half of the girls are bigger than I am, even though many of the tributes have never been fed properly. You can see it in their bones, their skin, the hollow look in their eyes. I may be smaller naturally, but overall my family's resourcefulness has given me an edge in that area. I stand straight, and while I'm thin, I'm strong. The meat and plants from the woods combined with the exertion it took to get them have given me a healthier body than most of those I see around me. - The Hunger Games
Gamemakers' accuracy score: 6/10 - Even though it was easy to forget about the physical differences thanks to how convincing Lawrence may have been during her rise to rebellion, her screen version was still older, taller, and much more well-fed than Katniss' written rendering … and that last difference wouldn't matter as much if, you know, the story weren't called The Hunger Games.
