Affleck and Pike play Nick and Amy Dunne respectively who personify the quintessential romantic match and modern married couple. But on the day of their fifth year wedding anniversary, Amy curiously disappears. Her vanishing becomes a kind of hall of mirrors in which tantalizing and savage secrets lead to even more tantalizing and savage secrets. The events that unfold are thick with shocks and complications, but the questions that remain are what cut, with razor-sharp precision, to the bone: Who is Nick? Who is Amy? Who are any of us in marriages -- and a society -- built on a precarious base of projected images and disguises?
Taking the alternately guarded and exposed role is Ben Affleck. Says Fincher of casting him: “Putting a cast together is like putting a basketball team together and Nick was the point guard. He has to feed the narrative. It’s a ‘he said, she said’ in the book; but it’s ‘he experiences, she experiences’ in the movie. It’s more subjective. You’re not gifted with all these inner monologues in the movie. So you need an actor who is very deft to play this role. It’s 3-D chess, not Chinese checkers."
