Directed by: David Fincher
Starring: Ben Affleck, Rosamund Pike, Neil Patrick Harris, Missi Pyle

Detective Rhonda Boney: Actually, I have never found that to be true.
Trivia: Hollywood actress Reese Witherspoon was a fan of the novel and purchased the rights, intending to play the role of Amy herself. However, once David Fincher was attached as director, she opted to serve only as a producer, realizing she wasn't right for the role.
