Amy Dunne

Amy Dunne (née Amy Wexford Elliott) is a fictional character created by Gillian Flynn in her 2012 novel Gone Girl. She is portrayed by English actress Rosamund Pike in the 2014 film adaptation of the same name. Described as "cold", "savvy" and "snobbish", Amy is a writer and diarist involved in a struggling marriage with her husband Nick Dunne. After learning that Nick has cheated on her with one of his students, Amy stages her own elaborate disappearance to have Nick arrested and executed for her murder.

Pike was cast as Amy after director David Fincher had seen her in multiple films but couldn't get a sense of who she was, a quality he felt was important to the character. While the character has received mixed reactions, Pike's performance received critical acclaim, which earned her multiple awards, including an Academy Award nomination for Best Actress in 2015.
