Which Austen novel was adapted into a 2005 film starring Keira Knightley?

The Austen novel adapted into the 2005 film starring Keira Knightley is 'Pride and Prejudice.' Directed by Joe Wright, the film adapts Jane Austen's 1813 novel about Elizabeth Bennet, a witty young woman whose first impressions of the proud Mr. Darcy gradually change.

Knightley plays Elizabeth, while Matthew Macfadyen plays Darcy. The cast also includes Rosamund Pike as Jane Bennet, Donald Sutherland as Mr. Bennet, Brenda Blethyn as Mrs. Bennet, and Judi Dench as Lady Catherine de Bourgh. Screenwriter Deborah Moggach retained much of Austen's dialogue while compressing the novel's large cast and detailed social plot for a 127-minute feature.

The film is sometimes confused with adaptations of 'Sense and Sensibility,' another Austen novel that became a major film in 1995. The 2005 production is particularly known for its location shooting, romantic visual style, and focus on the developing relationship between Elizabeth and Darcy. It received four Academy Award nominations, including Best Actress for Knightley.
