The Hunger Games (novel) [SEP] Film adaptation
The screenplay remains extremely faithful to the original novel, with Ross saying he "felt the only way to make the film really successful was to be totally subjective" in its presentation of events, echoing Collins' use of first person present in the novel. Twenty-year-old actress Jennifer Lawrence was chosen to play Katniss Everdeen. Though Lawrence was four years older than the character when filming began, Collins felt the role demanded "a certain maturity and power" and said she would rather the actress be older than younger. She added that Lawrence was the "only one who truly captured the character I wrote in the book" and that she had "every essential quality necessary to play Katniss." Lawrence, a fan of the books, took three days to accept the role, initially intimidated by the size of the production.
