Rozema employs "a collage or prismatic-like approach" in her adaptation of Fanny's character, incorporating elements of Jane Austen's character in order to update the "annoying" character for a contemporary audience. Rozema's modification of the character of Fanny Price, whom she considered an unpopular heroine, was to add colour and spirit by conflating her with the character of Austen herself, drawing upon her extensive juvenilia and letters. In the novel, Fanny is very shy and timid, and generally reluctant to give her own opinion. Her physical condition is frail, making her tire easily. In the film, in contrast, Fanny is extroverted, self-confident, and outspoken, while also being physically healthier.
