The Fanny Price in Rozema's 1999 Mansfield Park film adaptation is far different from the Fanny in Austen's novel. Rozema has recreated Fanny as a far more conventional romance heroine, spirited, assertive, and bold—a match for Mary Crawford. Rozema's is a fearless Fanny who advises her sister to "run wild" and who writes like her creator, Austen.
In order to create the bold Fanny, Rozema's deletes details of Austen's Fanny's timidity, such as her escapes to the old schoolroom to avoid the "the pains of tyranny, of ridicule, and neglect." We do not see either the scene where the frail Fanny is forced by Lady Bertram to cut roses in the heat so that she becomes fatigued and has a headache at the end of the day, causing Edmund to scold his mother and aunt. Rozema also deletes Mrs. Norris berating Fanny for being a "creep mouse" or Edmund telling Fanny that she must get used to be looked at admiringly.
Though Rozema's Fanny is much more overtly spirited and sexual, Fanny in the novel exhibits signs of both spirit and sexuality as she attends her first Bertram ball. Her beauty is praised by Sir Thomas, and Edmund says,
“You must dance with me, Fanny; you must keep two dances for me; any two that you like, except the first.”
She had nothing more to wish for. She had hardly ever been in a state so nearly approaching high spirits in her life.
Fanny also shows a great deal of spirit when she refuses to accept Henry Crawford's marriage proposal, despite intense pressure from Henry himself, her uncle, and Edmund. She won't even capitulate when she is banished to Portsmouth.
Though Austen's Fanny shows signs of sexuality, especially around Edmund, and spirit during the ball, as well as spirited strength of character in refusing Henry, the Rozema Fanny is a significant deviation from the original—truly a different character.
