Amy Elliott Dunne is a fictional character created by Gillian Flynn in her 2012 novel Gone Girl. She is portrayed by British 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 professor husband Nick. After learning Nick cheated with another woman, Amy orchestrates her disappearance to get Nick arrested.
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.
